Change colour scheme for individual features with PyGPlates

Q&A
1

Hi all,

I know “we can only change the colour scheme for all features, not individual features”
I wonder if someone has tried to symbolize a shapefile by any fields of attribute table with Python ?

Many thanks

Hi Fabrice,

If you’re talking about GPlates (rather than pyGPlates), then you might want to check out the Paleogeography tutorial.

Tutorial 2.6 from here: https://sites.google.com/site/gplatestutorials/

In there I provide an example of how a categorical colour palette can be used to map to a field in a Shapefile visualised in GPlates. Hope it helps!

Hi Fabrice,

Currently you can colour features by looking up a shapefile attribute in a CPT colour palette.

In the GPlates tutorials, there’s an example in exercise 1b of Tutorial 2.6: Introduction to Paleogeography.

Internally it uses a Python colouring script to extract the property from the feature and lookup the colour palette. You can see the script and discussion about that by Christian Heine here.

Regards,
John
