PowerChart Scaling for Y Axis in Log10 format

Ignition
1

Hello everyone,

I came across this situation where I want to show Y axis to be scaled for the range max = e3 and min = e-9 and with the axes props I was able to add the limits but when I add tags to the chart the scale is not working as per the min & max.

Has anyone able to configure something similar in the PowerChart component?

Try 1e-9 and 1e+3

And note that Property Explorer gives you a clue:

  • Green property values indicate that the data has been interpreted as being a string type (because they start with a letter).
  • Numeric will show up as orange.

Update: I tried with these limits but still for the minimum value scale is updating as expected

you used a capital E. Try a lowercase e.

For anyone looking at this in the future, I don't believe the PowerChart supports a Logarithmic scaled axes. The pictures above are rendering the min/max correctly but doing so on a Linear scale which is what the PowerChart uses.

You can use a Logarithmic scaled axes using the XYChart component which has a setting to achieve this.
