Good day
what map projections oher than Mercator are possible with the map versions of TeeChart?

Bruce

Hi Bruce,

TeeChart uses ESRI's shp files to create the maps as explained here: http://www.teechart.net/support/viewtop ... 725#p55070
But you are free to load any map you may find in the net. The map series is actually a list of polygons so there is no limitation on the shapes/countries proportions.

Hi Yeray
yes, I know that one can read in shapefiles but this does not control the projections e.g. Mercator, Mollweide, earth from space, etc. I know that Mercator is the default but would like to know whether it is possible to produce maps with one of the other projections. I could not find a way to do so in any of the map options but thought I had best check here on the forums.

Hi Bruce,

The only difference between projections (concerning TeeChart) is the list of points defining each polygon/country.
If you find a shapefile with a different projection than Mercator, I don't see why it shouldn't work or look as you'd expect.

Hi Yeray
Shapefiles do not contain projection information, only the coordinates for a series of points, based on a particular reference datum. All projection information in GIS is handled by the data frame, not the shapefile. As a result, it seems that one can not achieve what I want with the map series in TeeChart. It is unfortunate but not unexpected as TeeChart is essentially a graphing package, not a GIS system.

Thanks for your comments and help.

Hi Bruce,

Thanks for your comments and understanding.
I've added it to the wish list to be studied as a possible new feature in next releases (TV52016032).
