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?

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 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/1/51ba2fd14a58a722796b2c885d4844073ca62c37.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/c/acd1d14b94e305f6bdbf00819829747957d06fae.png) ---

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.
