Amazing video, this video is a proof that you were born to be a data techniques teacher and also, the information flow in the presentation and screenshots (especially the one putting the Dimension filters in between the FIXED and INCLUDE/EXCLUDE) make the trainee memorize what is the difference between the different types in terms of filter effect and answer any LOD-related question in interviews. Thank you so much
your way of teaching is simple yet deep, love it.. please do post more videos. I am preparing for my Tableau exam and your videos have been a great source for me to master. Thank you.
Respect Donabell 👏 Just finished the first part and can't wait to finish this series. I will save them in my favorites for reference. Way simplified compared to Britney's original video. Again, I know how much time you put to make hard easy and hope that you can get more lucrative rewards than ‘likes and thank you’, So THANK YOU!
Thank you Abderrahim :) Always appreciate your thoughtful and kind feedback. Glad to hear you found it helpful :) Thank you, thank you, for your support and encouragement. Your comments, along with many other supportive positive ones, really motivate me. Take care!
Hi, I have been working in analytics for quite some time. I have worked both as a business analyst and as a BI developer. Also, I had the opportunity to work with the most know BI tools in the market. I have to say this is gold for two reasons: 1) with these analysis a business analysis a analyst can keep a sales or marketing team busy for a very long time. 😁 2) the way you present I am pretty convinced Tableau is (after Excel - 😅) the best tool for those working in the business side. Thank you for sharing
Happy to see a video after gap, and the wait was worth it! Very nice explanation of LOD with practical examples, liked it! Awaiting next ones eagerly! Thank you Donabel! 😊👍
Vijay! Thank you, yes there was a little bit of a break 😅 I am trying to plan out the next videos now. Will be calculations heavy for the next little while. Thank you, as always, for your support! 😊
Thank you so much for your kind comment Charles! So happy to hear you found this follow up video a complementary one to the introductory LOD :) Very much appreciate your time (watching and leaving a thoughtful comment :))
wow I really love your videos. Your explanations are so easy to understand. In the past i did those exercises but i didn't understand some things but now i get it. Thank you so much for share.
Hi Donabel. I have a small question. at 26.21 when you toggle the segment the Grand Total and SUbtotal by region are not supposed to change but the Sales , % of Region total , % of Grand Total can change because the % of Region total , % of Grand Total depend on sum(sales) which is in turn affected by the "segment" dimension filter.
Aww. Thank you Fazlay, I hope this video was helpful for you. And your note is more than enough - thank you for taking the time to leave a comment. I appreciate it very much.
@@sqlbelle My Pleasure Ma'am, u r so much sincere. It's hard to learn a intuitive software like Tableau only from online resources. I am just a High School Graduate in Bangladesh, recently I got a lot of curiosity to Data Analysis that's why I started to learn Tableau. Thank u so much for your tremendous videos on Tableau. Your contents are just 10/10... Hopefully I will watch all of your videos and thus have a good ability on Tableau. Thanks again...!!! Best Regards.....!
Great tutorial, but to me, viz software should be abstracted away as much as possible from the data wrangling aspect of things. That is more efficiently achieved with SQL, pandas, etc..
Amazing Donabel! Your lectures are really helpful to get crystal clear understanding of Tableau Concepts. Your simple amd effective approach of explaining concepts are really cool. Will be waiting for new upcoming videos on SQL & Power BI. Love from Indian BI Developers & Happy New Year
Best tutorial available on the web regarding LOD. I have subscribed to your channel for future guidance. But a little upgradation may help visualization of videos. Your channel logo overlaps several times which is an obstacle to visualization.
Thank you Ma'am, your explaination are excellent. I understood everything explained in the video except @ 30:00 in the acquisition trend chart, I got the same chart, but when I changed week (First order date fixed) to day(First order date fixed) to check the counts manually on Excel sheet, I see difference in the way in which countd(customer_id) and count(customer_Id) is calculated. countd(customer_id) calculation is intuitive and it counts distinct customer_id on that particular date only. whereas, in count(customer_id) calculation it counts all rows of that customer_id including the particular date as well as other dates. Please explain why count(customer_id) counting rows of customer_Id for other dates also?
In customer acquisition trend use case, countd(customer_id) at a given min(order date) can also include those customer_ids that placed its 2nd or 3rd order on that day. Example: On 1st March 2017 five customers placed order for the very first time, including HR-14770. Tableau showing countd(customer id)=5 On 2nd March 2017 two customers placed order for the very first time. countd(customer_id)= 2. Now I added a row for one more order of HR-14770 on 2nd March 2017. This count should not be included for 2nd March 2017 because this is not HR-14770's very first order and HR-14770 is not a new customer on 2nd March 2017. But after addition of this row, countd(customer_id) for 2nd March 2017 changed from 2 to 3.
One comment at minute 7:50: Why do we have the same numbers for every year at the most frequent level (17, 13)? I interpret this report as follows: one customer bought 17 orders every year. If I add customers to the tooltip, I see the one who bought 17 orders every year, which seems incorrect. Do you think the calculated field should be modified like this: {FIXED [Customer ID], [Year Order Date]: COUNTD([OrderID])}?
"we have the same numbers for every year at the most frequent level (17, 13)" 13 7 17 1 consider 13 first: For this row grand total is 7, it means there are 7 distinct customers each ordered through 13 distinct order IDs. and for every year countd(customerID) is 7, means all these 7 customers ordered in 2017, 2018, 2019 and 2020. Similarly for 17 1.
Thank you so much. I have been learning it on my own to build these 15 examples, and when i had questions, I didn't know where to ask, and I was so frustrated, i wish I had seen these videos before. But i will go over the series videos as going over LOD again.
@@sqlbelle Noo !! Thank you !!!!! :-) , can you do a video about how to mix an aggregate argument e.g. sum(Sales), avg(Profit), Profit Ratio with non-aggregate arguments e.g. Discount ? please :-)
Hey, great work. I have one doubt. When you talk about the acquisition of customers, why did you consider those customers which we already had on that day, why did we not exclude them? I mean old customers should be deducted first and then the running total should be calculated such that we can know how much have we gained each day cumulatively to get the trend. If there is a problem in my understanding or there is no need for it then plss correct me. okay okay, you have also done the same by using the fixed level of details where you have only selected the customer's first purchase only hence only new customers are getting captured. great got it now thanks!
Hi sqlbelle, I tried the other way before checking the video Just by understanding the question , the calculation for checking profitable and non profitable days as follows : Profitable : COUNT({fixed [Order Date] : IF SUM([Profit]) > 0 THEN SUM([Profit]) END}) Not Profitable : COUNT({fixed [Order Date] : IF SUM([Profit])
Thanks for trying this out. You are absolutely correctly, there are multiple ways to achieve something similar in Tableau. But each could have their own nuances.
Thank you You! Please do check out my first LOD video (the link is in the description). It goes into detail as to what LODs are, and why and when we would use them. Hope you will find that video helpful!
I have one query , when you drag and drop [Order date] , tableau ask for continuous and discrete column value, but not in my case when i work on my machine, Do i need to enable any setting??? Please suggest....
Hey hi I wanted to make a cohort for employee retention how do I do that I used the same logic what you have used here i am getting diagonal matrix but not getting upper matrix. Can you please help me
how are you writing FIXED and other TEXT with your mouse for annotation? i use presentity as well, but not sure how you write with it. do you use any digital tablet and a pen to write it ? (time at 16:03 where you write FIXED)
Thanks. The result is slightly different, and may affect other use cases. MIN([Order Date]) returns an exact date field. May not be obvious when you drag this because Tableau rolls up to YEAR right away. MIN(YEAR([Order Date])) returns an integer. In the specific use case in the video - may not matter since we are just displaying. For other calculations, it will.
This video is fantastic and I like the way you simplify the complex points however at 26:23 the numbers are changed in % of region total and % of Grand total despite you using fixed expression and as per my understanding Fixed overrides any dimension that encounter , can you please correct me if I am wrong or explain why its changed,, Thank you for your amazing effort
The number of % is changed, The reason behind the formula contains the sum of sales, which is why the sum(sales) change affects on %, although ma'am spoke wrong there.
Is there something new introduced by Tableau like LOD editor (where you don't need to remember the syntax for LOD)? I saw it somewhere mentioned but cannot find any video presenting it.
You may be referring to the Quick LOD? It is a new feature, but has limited use at this point. Here is a reference: help.tableau.com/current/pro/desktop/en-us/calculations_calculatedfields_lod.htm#use-a-quick-lod-expression
In use case 4 min 26:40 when the filters are added the % of region and % of total DO change. It sounds like you are saying that the percentages should NOT change. Any clarity on this would be appreciated.
As per my understanding, % of total country sale should be calculated as "sum of each country sale / Grand total sale" and % of total region sale = "sum of each region sale / Grand total sale" But here she has taken "sum of sale " which is at state level
As usual good explanation. I have one point here regarding Case 3 i.e. profitable vs unprofitable. Instead of creating 2 calculated fields - one for LOD and other for conditional grouping based on LOD, we can directly create single field where LOD and condition for profit can be used. IF { FIXED [Order Date]: SUM([Profit]) > 0 } THEN 'Profitable' ELSE 'Not Profitable' END I have checked the result and got the same viz as u created. Are there any problems or drawbacks with my approach? pls highlight.
Thanks Shashank. Some of the questions around nested calculations are around clarity, reusability and manageability. If you ever need to use the total profit per order date again in another view, it's better to put it in a different calculation. Otherwise you will have to embed this expression every time you need it. It will make it harder to update as well, in case it needs to change. For clarity and for teaching, and especially for folks who are new to LODs, it is easier to explain and understand if we break up the logic into simpler expressions first, rather than using a nested expression right away. For clarity when you are working with other members in your team, having separate expressions may be easier to understand as well. As with anything, everything is relative. There is no one right answer, and you have to go with what works with you and your team.
@@sqlbelle Perfect! Makes sense. Also do you have any course where tableau is taught by you from the start to advance level? If not, what course do you recommend where uses cases are also taught well.
hey this is good example of Lod - Fixed , but one question i had at question 4 , mins 26 in the video , you mentioned that after adding all the calculations in the map , only the sales value should change with Segment , but , percentage of region total and percentage of grand total also changes , could you clarify please
I am facing the same issue as well. Her contents are really good, but the only downside is , when you have doubts you cannot get it cleared. That's where probably structured courses / MOOC's might come in more handy. Nevertheless her courses are still a value add
Hello. Because the number is not additive. For example, if you bought 5x in 2018, and in 2019, and in 2020 as well as 2021 ... you wont be counted as 4x in the grand total because you are still just one, unique, distinct customer.
Thank you for your feedback Avinash, I appreciate it. I just realized I had the filter I had in the video was for segment but it should have been region as per 22:07. I will make a note in the description.
@@sqlbelle Most welcome. I love the style of your teaching and I am learning from your video while giving interview. Today is my interview. Thanks a lot for giving so much valuable knowledge ☺️
Thank you Hemalatha. I have another video that tackles it, and I also discuss some pros and cons of building it in single sheet vs separate sheet. I am curious to the reasons for needing it in a single sheet? th-cam.com/video/e8yQGdKG6dI/w-d-xo.html
Hi Donabell, how did you organize your use cases into Folder in the data tab, and how Tableau decide where a calculated field will be displayed (attached to a table of at the end below the Measure Names). I'm new to tableau and have trouble navigating these things. Thanks for your great lessons
Hello Xuân! You can click on the dropdown in your side bar (beside search and data grid) and select "Group by Folder". Once you have that you can create a folder on the side bar (right click on an empty space, or right click on a field > Folders). Hope this helps!
Absolutely amazing Donabel! Thank you for sharing. You're 10X better at explaining than most paid video courses on LOD's.
Thank you Franco :) Glad to hear you found it helpful!

Now I added a row for one more order of HR-14770 on 2nd March 2017.
This count should not be included for 2nd March 2017 because this is not HR-14770's very first order and HR-14770 is not a new customer on 2nd March 2017.

"we have the same numbers for every year at the most frequent level (17, 13)"
13 7
17 1
consider 13 first: For this row grand total is 7, it means there are 7 distinct customers each ordered through 13 distinct order IDs.

Thanks Fajar. You can embed logic statements in the FIXED LODs, so you can technically address these cases.
Hi sqlbelle,
I tried the other way before checking the video Just by understanding the question
, the calculation for checking profitable and non profitable days as follows :
Profitable : COUNT({fixed [Order Date] : IF SUM([Profit]) > 0 THEN SUM([Profit]) END})

8:10, why does each column and row add up not the equal to the grand total? I don't understand the quick explanation in the video. Thanks.
Hello. Because the number is not additive. For example, if you bought 5x in 2018, and in 2019, and in 2020 as well as 2021 ... you wont be counted as 4x in the grand total because you are still just one, unique, distinct customer.
@@sqlbelle Hi Belle, than you, I got it!
Adorable.
You said value should not change at 26:21 but % of grand total and % of subtotal are changing
Thank you for your feedback Avinash, I appreciate it. I just realized I had the filter I had in the video was for segment but it should have been region as per 22:07. I will make a note in the description.
@@sqlbelle Most welcome. I love the style of your teaching and I am learning from your video while giving interview. Today is my interview. Thanks a lot for giving so much valuable knowledge ☺️

How to show kpis and sparklines in a single sheet , make a vedio on it mam.
Thank you Hemalatha. I have another video that tackles it, and I also discuss some pros and cons of building it in single sheet vs separate sheet. I am curious to the reasons for needing it in a single sheet?

Hi Donabell, how did you organize your use cases into Folder in the data tab, and how Tableau decide where a calculated field will be displayed (attached to a table of at the end below the Measure Names). I'm new to tableau and have trouble navigating these things. Thanks for your great lessons
Hello Xuân! You can click on the dropdown in your side bar (beside search and data grid) and select "Group by Folder". Once you have that you can create a folder on the side bar (right click on an empty space, or right click on a field > Folders). Hope this helps!
