    Respected sir @24.40 there was negative y intersept isn't it? as the green line was passing below origin. By the way great video. Subscribed!!!

    How do you plot error bars on a log plot?!

      @@LouisWongPhysics Cheers this helped a lot. I'm still not certain about the length of my error bars because I do not know the absolute uncertainty of the instrument I used (A high voltage power supply that was displaying a count of nuclear decays). I am going to just go with the absolute uncertainty being 1 - which doesn't sit well with me, but I have been researching long enough and need to get on with other work. The instrument displays a count of nuclear decays, which is only ever going to be an integer.

      ​@@CHEESYhairyGASH In this case I would probably just repeat the trials and consider the data scattering for the uncertainty. Agree with you. Your display is an accurate integer.
