    I'm currently working with implementing new chartview into our reportingsystem . Chartview with it's multiple different options looks quite good, but I ran into problem with trackball and formating information on it. Basically I would like to get multiline box which is located over the lines/boxes and also numeric values with certain format instead of how it looks atm (screenshot edits: removed ends of legend information+ start of y-axis labels due information they had). I'm populating the chartview dynamically from datatable with n-series.

    Can this be achieved atm? Did I miss some setting?

    (using Q3 2012,, winforms application)

    Hello Antti,

    Thank you for writing.

    You can use the TextNeeded event of the TrackballController to customize the text. Here is an example:
    ChartTrackballController trackball = new ChartTrackballController();
    trackball.TextNeeded += trackball_TextNeeded;
    private void trackball_TextNeeded(object sender, TextNeededEventArgs e)
      e.Text = "My text";

    I hope this will be useful. Should you have further questions, I would be glad to help.
