Prevent excessive zoom + zoom & multiple axix

[marc_x]

Hi,
Is there a way to prevent the user to zoom beyond a certain point. for example when the interval of the bottom axix has reached a certain value.

Is there a way to allow zooming 1 Y axes when multiple Y axes are present, my tests show so far the zooming when multiple Y axes are present only works ok on the X axis. If not what would be my options.

Thanks

Please add to component OnBeforeZoom event

2nd question still pending

Zooming is not supported on custom axes. Please read this FAQ item on how to zoom custom axes.

Thanks in advance.

Hi marc_x,

Please try using Chart.Zoom instead of IZoom, for example:

Code: Select all

  Chart1.Zoom.X0
