| 3 | Configure plotter for plottools. |
|---|
| 4 | |
|---|
| 5 | This must be imported first in __init__.py for plottools. |
|---|
| 6 | |
|---|
| 7 | If your application uses matplotlib outside plottools, then |
|---|
| 8 | please do the following at the start of your application: |
|---|
| 9 | |
|---|
| 10 | # Select matplotlib version and backend |
|---|
| 11 | import sas.sasgui.plottools.config |
|---|
| 12 | |
|---|
| 13 | Note that plottools requires particular versions of matplotlib |
|---|
| 14 | and a particular backend. As of this writing it is the WXAgg |
|---|
| 15 | backend for matplotlib>=0.98. |
|---|
| 16 | |
|---|
| 17 | The plottools package uses pkg_resources if available to select |
|---|
| 18 | the correct version of matplotlib. If you need multiple matplotlib |
|---|
| 19 | versions in your path, be sure to use "easy_install -m" for all |
|---|
| 20 | of them. If a version is installed without "-m" that does not |
|---|
| 21 | meet the requirements, then pkg_resources.require() will fail, |
|---|
| 22 | even if you have installed a suitable version with "-m". In this |
|---|
| 23 | case you will need to fix up your site-packages directory, |
|---|
| 24 | probably by removing site-packages/matplotlib and the associated |
|---|
| 25 | egg file for that version, and reinstalling with "-m". You may |
|---|
| 26 | also need to edit site-packages/easy-install.pth. |
