[Qgis-developer] custom charts?

[Raymond Nijssen]

Here is an example of a map with code generated svg images as symbols.
The quick and dirty script does:

- aggregate all features from input point layer with same geometry
- calculate min/max times and values for whole set
- create svg files for every feature with filename based on id
- create a layer in qgis

Manually i added the data defined filename based on the id:

'/tmp/img_measure_' || "imgid" || '.svg'

Et voila!

Thank you all for your suggestions!
