Select a data range on line chart to zoom

I am using the lastest tee chart with Delphi 2006 VCL. I have a dbChart with numbers on the y-axis and dates on the x-axis. I have a ChartPage Navigator that allows 10 points per page. I want to use the mouse to select some points on the chart and zoom into that date range. Can you help me?

Hi McMClark,

Haven't you tried TeeChart default zooming feature? Maybe setting the zoom direction to horizontal will be better for what you are trying to get. You'll find examples about that at in the features demo. All Features\Welcome!\Miscellaneous\Zoom and Scroll You'll find the new features demo at TeeChart's program group.

Another option would be that you used axes SetMinMax method to set their minimum and maximum values.
