There seems to be a bug with the XY Chart where the number format set on one axis is applied to the other axis or for another configuration object on the same axis. I experienced this bug on Ignition 8.0.12, then tried on 8.0.15 and saw the same thing.
Consider this screenshot:
Note how the left side, right side, and bottom are all currency formatted. This is what is displayed even though I only set a single axis to have a currency format. The other two number formats seem to be ignored or overridden.
I did this using the default XY Chart component so as to be easy to reproduce. I only made two changes to its properties, and both can be seen in the property editor on the right side of the screenshot:
- I changed the
yAxes[1].value.formatproperty to have a value of$#,###. This changed both the Process Temp and Output Temp formatting to have a $ in it. That change of formatting should only have applied to the Output Temp. The format for Process Temp (#,###.##) seems to be ignored. - I changed the
xAxes[0].renderproperty fromdatetovalue. Obviously it is odd to change a date value to be rendered as a numeric value, but notice that if you do this then the currency formatting is applied to the X axis too.
So not only is a format in one of the Y axis configurations affecting other Y axis configurations, but it’s also affecting X axis configuration too.
Is there any way to fix or work around this issue? I want to have X and Y axes that are both numeric but not have one format override the other.
