Custom format or content of labels shown besides the TrackBallInfo

[Pavel Filip]

Hello,

I am struggling big time with TrackBallInfo.

I want to achieve, what seems to be a very simple thing:

I have a numerical Y-axis, which I configured this way:

<chart:SfChart.SecondaryAxis>

    <chart:NumericalAxis EdgeLabelsVisibilityMode="Default"

                                       EdgeLabelsDrawingMode="Hide"

                                       Minimum="{Binding Path=MinimumY}"

                                       Maximum="{Binding Path=MaximumY}"

                                       LabelFormat="0.00" 

                                       FontSize="12"

                                       ShowTrackBallInfo="True"/>

</chart:SfChart.SecondaryAxis>

Now, I want the TrackBallInfo not to contain the Y-Value in the format that is shown on the Y-axis, but I would like to format it in the way, that I decide, or rather configure in my config file.

So to say, I want to be able to change it to scientific format, or 7-digit precision, or some text (e.g.: GOOD, BAD, SUPER, DANGER, ... whatever, you got the point, right?).

How can I achieve this?

I mean, If I set the format in LabelFormat for the axis, it is fine in the TrackBallInfos, but wrong on the Y-Axis labels, where I only need to show 2 decimal points.

Thanks for your help!
