Multiple axis with zooming

[Vikas Aggarwal]

For Charts with multiple axis if we apply zooming it works only with first left axis and the labels on x axis are displayed only only for first left axis.

Hi Vikas,

Yes, custom axes don't zoom. However you can implement this by doing something like what's told on this FAQ item.

Hi,
The Response in FAQ is for Delphi. Can we get c# code. We have Custom" axes labels (Y-axes) that are not getting updated after zoom.

Thanks
Vikas

Hi Vikas,

I've added two line series, line2 having a vertical custom axis (axis1) associated with custom labels. Zoom works fine for the custom axis using this code:

Code: Select all

    private void Form1_Load(object sender, EventArgs e)
    {
      line1.FillSampleValues();
      line2.FillSampleValues();

      axis1.Labels.Items.Clear();

      for (int i = 0; i < line2.Count; i++)
      {
        axis1.Labels.Items.Add(line2.YValues[i]);
      }
    }

    private void tChart1_Zoomed(object sender, EventArgs e)
    {
      axis1.SetMinMax(axis1.CalcPosPoint(tChart1.Zoom.y1), axis1.CalcPosPoint(tChart1.Zoom.y0));
    }

    private void tChart1_UndoneZoom(object sender, EventArgs e)
    {
      axis1.Automatic = true;
    }
