Bubble series with independent radius for vert and horiz

[SteveP]

Could independent radius be added for the Bubble series (VCL) vertical and horizontal axis. I specifically need a rectangle with X,Y center point having different vertical height and horizontal width in terms of data value. The Bar3D series almost does this but does not have a center value.

Hi Steve,

I've already added this to our wish-list to be considered for future releases, however you have some alternatives to this as would be:

1.- Using Shape series.
2.- Using Map series.
3.- Drawing directly on the canvas.

1) Shape : A separate Shape series has to be used for each individual data point ? When using thousands of points, that's a lot of series. Also, no Snap cursortool ?

2) Map : more trouble to add points to than other series. Cursortool with Snap - true did not work for me.

3) Draw onto canvas : I'm currently preparing a bitmap from the dat and using that as the backwall bitmap. Then adding fake series used for cursors, etc. I'm trying to get away from all that with my requested Bubble modification.

Thanks for the consideration. Hope to see it...

True.

Please have a look at the TeeMaps demo available at C:\Program Files\Steema Software\TeeChart 704 for Delphi 7\Examples (default english installation path). It is currently using map series and a cursor tool. CursorTool snap property doesn't work for map series but works for "cities" point series. You may use a "dummy" point series, with values at the poligon center, to get this behaviour.
