    So glad I found this tool. I've been dabbling around with creating something like it, not knowing it exists, but it's so tangential to what I am doing that my enthusiasm has been nearly zero. My use case is solving aircraft performance graphs, where we don't even care about the underlying data, only the slopes. This should be enormously helpful.

    This works GREAT. It picked up the points automatically off of a picture of a graph and put them into a table no problems at all. Only suggestion is to make the highlighter / area limit a little clearer in the UI. You can create a nice suite of engineering productivity software and license it to large firms!

  • @markszlazak
    @markszlazak 4 ปีที่แล้ว

    Thank you. Sorry if i missed this but say I have multiple curves on a graph that use the same X and Y axis (e.g. each curve is voltage(Y) versus time(x) for one other parameter value, there are a several parameter values and therefore several curves on the graph. If you are familiar with IC datasheets then you know what I mean.). For one value of Y (voltage), I would like to get the value of X (time) for each of these curves. Basically, the intersection of a horizontal line starting at some Y that intersects each curve. Is there some like your "mask" but for a line that does this. Doing this by hand where you place try to place intersection points on each curve is a bit tedious and probably less accurate. Thanks.

  • @joanafernandes5709
    @joanafernandes5709 3 ปีที่แล้ว

    Hi! I would like to insert an additional reference point to a date+time X-axis, as I only have one point for which I know the exact time and date. For the other reference points, I only have the date information. I have read the manual which states that "to highlight a different point than what is already selected, you just need to click on the other point after the four points have been placed on the screen.".
    As english is not my 1st language, I am unsure if this sentence means that I should be able to select 5 reference points or if this is an indication that I should be able to tweak the already selected points. If the first hypothesis is true, I have been unable to select the 5th reference point.
    I also thought about using the point I have the time+date information, as a reference for the X-axis, but I fear that giving time information for only one of the 2 reference points, would make the software attribute a timestamp to the point for which information is absent.
    I would really appreciate some help, it would really make a difference in the development/accuracy of my master thesis!
    Please reach out :)
    Thanks!

    What about for multiple y axes having one X axis in a figure??
    How can we can we get SAME X axis value for different Y axes? For example: TG-DTA-DTG graph, where there are 3 Y axes against X (Temp).. And we have to plot them against a Constant X axis values..

  • @josefmolines5975
    @josefmolines5975 8 ปีที่แล้ว +1

    I love this software. I'm having problems with the calibration for tilted images. Shouldn't be better to give (x,y) for the 4 points during calibration?

    • @ankitrohatgi
      @ankitrohatgi  8 ปีที่แล้ว +1

      The current XY calibration does a simple affine transformation, so it can account for scaling, pure rotation in XY plane and shear (X-Y not at 90deg). For this, only the x1,x2 and y1,y2 at the points are needed to satisfy the transformation equations. If your image has perspective distortion, only then (x,y) at all 4 points are needed. It is on my to-do list to add support for perspective distortions eventually.

    this is a great webtool, much better than a lot of offline equivalents I've been using over the yeard. The opensource nature of the product is very important and I've dontated accordingly.
    Concerning the workflow dispalyed in this tutorial: I really wish, I could introduce corrections in the axes calubration and re-run the digitizing procedure without starting the entire thhing from scratch. Example, if I have missed the "log scale" checkbox or made a typo in a single value, I have to initiate the axes calibration procedure all the way from beginning, defining X1,2 and y1,2 again. Can we please have a button to bring up that X-Y calibration windown again, so I can just correct a value and press "Apply"?
    Thanks again for the wonderful software.

      I was selfishly hoping for something less time consuming. So here is my suggestion for an additional feature: provide a mechanism that recognizes vertical and horizontal lines that are parallel to the axes and ignores them.
