Axis ticks and labels

[Dev01]

Is it possible to have an Axis to display only tick marks an no labels?
It looks like when I set labels visible to false the ticks go away.
I am using WPF TeeChart 4.1.2014.5092

Thanks in advance.

Hello Dev01,

Yes, you can set label text to a blank space in the GetAxisLabel event, for example:

Code: Select all

    void tChart1_GetAxisLabel(object sender, GetAxisLabelEventArgs e)
    {
      if (sender.Equals(tChart1.Axes.Left))
      {
        e.LabelText = " "; 
      }
    }

Thanks Narcis. I know this works, but isn't there a clean way of doing it - like enabling only ticks without enabling the labels. Because technically we are using up memory for those invisible "white space" labels and I am not sure how will it get disposed.

Thanks,
Dev01

Ok, I added your request to bugzilla (ID1052). Feel free to sign up and add yourself to the CC List to receive updates on the issue.

The next TeeChart update, which will be published very soon, will cache those texts so only one object will be created for such labels. This will mean very little memory impact. Also bear in mind that the .NET Framework is a garbage collected environment and this job is done automatically when disposing an object although objects are immediately freed, it's garbage collector who does that task. Therefore you may see memory consumption oscillations in your application. At this thread you'll find a more in deep discussion on garbage collector and TeeChart.

My colleague Christopher Ireland just reminded me that this is is already possible using the TickOnLabelsOnly property, e.g.:

Code: Select all

      Steema.TeeChart.Styles.Line series = new Steema.TeeChart.Styles.Line();

      tChart1.Aspect.View3D = false;
      tChart1.Series.Add(series);
      series.FillSampleValues();

      tChart1.Axes.Bottom.Labels.Visible = false;
      tChart1.Axes.Bottom.Ticks.Visible = true;
      tChart1.Axes.Bottom.TickOnLabelsOnly = false;

Many apologies for having missed this property and the inconvenience it may have caused.
