Respected sir,

i have been using charting in my VB.NET windows application using DataVisualization..
i want to zoom this chart using specific keys on keyboard...
i am using following code..but i want vertical zooming too..and following code does not show the proper result..

VB

.ChartAreas(0).AxisX.ScaleView.Zoomable = True
.ChartAreas(0).AxisY.ScaleView.Zoomable = True

.ChartAreas(0).CursorX.AutoScroll = True
.ChartAreas(0).CursorY.AutoScroll = True

What does the code do? You say it does not show the proper result but what is it doing?

above code is only does horizontal zooming not vertical zooming..

Don't see a reason why this question should be popular. Sorry but a good zoom is that old than graphics is available....and don't tell me it has to be re-envented with .net

This is what worked for me:

Chart1.ChartAreas(0).CursorX.IsUserSelectionEnabled = True Chart1.ChartAreas(0).CursorY.IsUserSelectionEnabled = True
Chart1.ChartAreas(0).AxisX.ScaleView.Zoomable = True
Chart1.ChartAreas(0).AxisY.ScaleView.Zoomable = True
Chart1.ChartAreas(0).CursorX.AutoScroll = True
Chart1.ChartAreas(0).CursorY.AutoScroll = True

The code apparently allowed to use a mouse to select a specific region of the graph and it zoomed into it on both axes.
