[Qgis-user] Announcing ChartMaker plugin

As far as I can tell, the Statist plugin is giving you statistics for
an attribute, like maximum, mean value, ... and it also displays a
nice histogram with the frequency distribution.
With the ChartMaker plugin my intention is different: being able to
simply plot two attribute fields (or more, using more data series), to
show a graphical representation of the data. So the ChartMaker plugin
applies to pairs of fields and plots them, without giving the user any
stats (for that the Statist plugin is doing quite well!)

Yeah, you're right. I'll look into it later. Thanks for testing it out ;)
