I’m glad that helped!
Most, if not all, of the chart components in Ignition are based off of the JFreeChart library. I remembered .getChart() from some other forum post here to get the actual JFreeChart object, and from there it’s just surfing through the documentation to find out how to get the axes and their respective values.
You can see what classes you are working with using .getClass()
The class names don’t exactly match JFreeChart, likely because Ignition uses wrapper objects to allow bindings, etc. I may not even be looking at the correct classes (I’m not really a java guy, so I have to wing it), but it’s usually close enough to figure it out. I assumed these were the corresponding classes:
object returned from getChart()
object returned from getChart().getPlot()
object returned from getChart().getPlot().getDomainAxis().
