- LIMITATIONS
Eastwood has the following limitations:
- Maps are not implemented;
- radar charts are not implemented;
- Venn diagrams are not implemented;
- the Google-o-meter chart is not implemented;
- QR codes are not implemented;
- the 'chbh' attribute is ignored, and bar widths are automatically
calculated to fit the available space (this is actually easier than
trying to figure out the right values for the 'chbh' attribute, which
looks like a bit of a kludge to me);
- stripe fills are not yet supported;
- area fills are not yet supported;
- chart markers are not fully supported yet.
If there are other items that you think should be listed here, please post a bug report.
