[ANN] ltk-plotchart

[Peter Lane]

Hi list,

I have written a wrapper around the tklib/plotchart library to work with
LTk. This includes over 20 different chart types (xy-plots, gantt
charts, 3d-bar charts etc...). Many examples ported over from TCL appear
to be working well.

For information and to download, see:

Let me know if you come across any problems. So far I've only tested it
on the included examples.
