Automatically format axis labels when numbers get too large

[Karim]

Is there a way to automatically convert the axis labels into exponential form when the numbers get too large? On my Y axis, I have values ranging from 0 all the way up to 90000000000. It would be nice if, after the length of the value got to be bigger than say 5, that it would covert the label to 9e10 or something similar. Otherwise, it starts messing with the formatting of the rest of the chart.

I tried the following:

chart1.PlotArea.YAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.Scientific;

but that still carries with it a lot of decimal points (e.g. 9.000000E-10), which ends up making the label take just as much space as it did otherwise. Is there a way to specify what decimal place it should round to?

Hello Karim,

You can set the CustomFormat property to any valid Standard Numeric Format String or Custom Numeric Format String. For example:
chart1.PlotArea.YAxis.Appearance.CustomFormat = "0.###E+0"

Hope this helps.

Had read about custom formats earlier, but had forgotten. Thanks!
