How to disable zooming by dlb click?

There are two ways to zoom on a Tchart: (1) Click and drag a zoom box, and (2) double click and size the zoom box. I want to disable the 2nd method, but keep the 1st method intact. How do I do this?

On this graph, I would like to be able to click anywhere on the screen and then get the real world XY ground (terrain) coordinates of where the m...

This is a reply from a similar post on the About Delphi forum: From: spgilmor1 11:30 am To: drmhstevens 2 of 2 11833.2 in reply to 11833.1 It sounds like you're confusing overriding with events. The error message you're getting is because you're marking DoGetImage() with the override keyword. This t...

I am trying to extend the TCustomImagePointSeries class so that I can assign a different bmp stored in an ImageList (actually 1 out of a list of 9) to individual points in the series. I've been following the TErrorEllipse example you sent, but I am stuck at how to over_ride the OnGetImage property? ...

Hi, I seemed to have resolved the problem by systematically turning various "visible" properties and finally got the pointer to show.

Thanks for the help,

In one the pointer line is clearly visible, in the other it doesn't appear no matter what I do to set it's properties via the Delphi Object propertes Inspector or by using the TeeChart embedded editor?

The blue wire outlines in the first bmp are more or less perfect squares (overlapping) where the aspect ratio between x and y are equal on the screen. I achieved this by resizing the Chart1 window by hand and eyeball untill the aspect ratio looked approximately correct. In the second bmp, the diagra...

Narcis, I turned off the bottom and right anchors so now it is only anchored at the top & Left. I also set BackImageMode to pbmCenter and AutoSize to false, but I still get the same problem, which is that the diagram stretches unevenly (distorted) to fit the resized Chart window area. The chart also...

Export to DXF

I did some Googling and found some Delphi code that I think could be easily incorporated into TeeChart to provid a basic export to DXF. Steema would need to devote some resource for only a short while I think. This would be a huge feature for folks developing software in the GIS/GeoSpatial industry ...
