  Hello, I’m creating a log-log chart and would like both the x and y axis to have labels displayed as 10 to some power. See the right image below which shows a sample log plot. As can be seen, it can go negative and positive. How do I replicate axis labels like that?

  This solution seems to work ok: https://canvasjs.com/forums/topic/logarithmic-function/

  If there’s a better way to do it nowadays, I’d be glad to see.

  Thanks!

  @joshuasosa,

  You can show axis labels in exponential form with the help of unicode characters as mentioned in this thread. Please take a look at this JSFiddle for an example.

  I was having trouble with subscriptValue producing 10^0 for 0.1 in some cases when it should be 10^-1.

  subscriptValue using Math.log10(value) fixes the issue for me, instead of Math.ceil(Math.log(value)/Math.log(10))
