Click event for Label ?

Hi, is it possible to catch events for clicking on the labels for
a series (the value/name on the y-axis)?

Hi Jakob,

I've post one example which show you how to do this in VB.Net (WebApplication) to the steema.public.attachments newsgroup.
Hope that help you.

Hi. I have looked at this sample, but it handles marks instead of labels.

I am trying to solve this by implementing the onClickBackground event, but the problem is that when I get there, the Labels collection of my axis is empty?

Code: Select all

private void onClickBackground(object sender,  ImageClickEventArgs e)
{
foreach( AxisLabelItem li in tChart1.Axes.Left.Labels.Items)
{
  if( li.ShapeBounds.Contains(e.X, e.Y) )
  {
     .....

What am I doing wrong?

Hi Jacob,

What am I doing wrong?

Well, AxisLabelItem is used for Custom Labels, no default labels, as can be seen in the Feature Demo under:
All Features -> Welcome! -> Axes -> Labels -> Custom Labels.

To use your technique you would have to populate your Left Axis with Custom Labels.

I will add a ClickAxisLabel event to the wishlist of the TeeChart for .NET component.

Hi Christopher,

I have tried this, I added custom labels to my left axis, and in the onClickBackground event, I can find the labels.

However: The ShapeBounds property of the label items are always 0, so how can I find out which one that was clicked?

You can get this to work by setting the AxisLabelItem to Transparent = false, e.g.

Code: Select all

tChart1.Axes.Left.Labels.Items.Add(50, "HELLO");
Steema.TeeChart.AxisLabelItem tLabel1 = tChart1.Axes.Left.Labels.Items[0];
tLabel1.Transparent = false;
tLabel1.Pen.Visible = false;
tLabel1.Brush.Visible = false;
