  Hi all,
  
  knows somebody how to :
  1) zoom-in, zoom-out chart by mous click ?
  2) scrool min and max values in X axes ?
  
  For scrolling I have used :
  
                  myChart.PlotArea.XAxis.AutoScale = false;
                  myChart.PlotArea.XAxis.IsZeroBased = false;
                  myChart.PlotArea.XAxis.AddRange(0, 20, 1);
  
                  myChart.HorizontalScroll.Enabled = true;
                  myChart.HorizontalScroll.Visible = true;
                  myChart.HorizontalScroll.Minimum = 0;
                  myChart.HorizontalScroll.Maximum = 2000;
                  myChart.HorizontalScroll.SmallChange = 1;
                  myChart.HorizontalScroll.LargeChange = 100;
  
  but i see only fisrt 20 values...is not possible scrool to another.
  
  Thanks for your help

  Hi Ales,
  
  I am afraid zooming and scrolling is not directly supported in RadChart for Windows Forms. You can check Nikolay's suggestion to place the chart in a panel and use automatic scrolling.
  
  Best regards,

  Q3’11 of RadControls for WinForms is available for download (see what's new). Get it today.

  Could you set the charts visible attribute to false, then draw the chart as a bitmap into a container setting it to stretch then grow and shrink the container to pseudo zoom? Crazy idea but...
