Hi all (again), I made some searches in the forum and found another similar question that gave me an idea, so i wrote two small routines that now give me the values that i need (see below in blue). What I am wrestling with now is how or which mouse click action to associate with this calculation. I ...

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?

I have written a mapping application uses a Tchart where I have plotted several series of data that represent ground points and Aerial camera XY stations. 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,

Hi, I am using a ChartTool1 : TAnotation Tool in two different forms. 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? Should I try setting it visi...

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...

Thanks a bunch. Ok now I see it.

I have the Pro version of TeeChart and looking for a TannotationTool icon in the component bar but don't see it? should it be there? If not How doe I manual insert this oject?

Sorry forgot to provide the link: DXF Read/Write/Display // // ©John Biddiscombe // // Rutherford Appleton Laboratory, UK // // j.biddiscombe@rl.ac.uk // // DXF code release 3.0 - July 1997 //

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 ...

Is there a simple example posted of how to explort the contents of a chart to PDF format. I want to plot a simple scale diagranm of XY points and some aerial footprint vectors.

I am plotting point positions and vector line to a Chart 7 but my diagram is distorted or stretched to the extents of the window size for the chart. I want to view the diagram at a correct proportional scale where X is scaled correctly relative to Y? What properties need to be turned ON or OFF? Than...
