Hi @mlmarius, the "Design" page was more of a roadmap for us than a tutorial. Sadly, we let it get out of date. We're working on updating the documentation (#201). We haven't implemented makecpt yet because there are still some issues with how we're communicating with the C API. Right now, there is no way to call GMT modules directly. We'll update this issue when we have makecpt implemented, so you'll get a notification. |

Initial commit for wrapping the makecpt function raised at #214, tentatively implemented here under the mathops.py file which will hold functions for "Mathematical operations on tables or grids", but with documentation placed under 'Plotting'. Original GMT `makecpt` documentation can be found at https://docs.generic-mapping-tools.org/latest/makecpt.html. Tests are stored under test_makecpt.py, and there are now some basic tests ensuring that we can change the color when plotting points and grids. Current implementation uses 'cmap' and 'series' as aliases for 'C' and 'T' respectively.

* Wrap makecpt Initial commit for wrapping the makecpt function raised at #214, tentatively implemented here under the mathops.py file which will hold functions for "Mathematical operations on tables or grids", but with documentation placed under 'Plotting'. Original GMT `makecpt` documentation can be found at https://docs.generic-mapping-tools.org/latest/makecpt.html. Tests are stored under test_makecpt.py, and there are now some basic tests ensuring that we can change the color when plotting points and grids. Current implementation uses 'cmap' and 'series' as aliases for 'C' and 'T' respectively. * Enable makecpt to save to a cpt file via output (H) parameter Allow makecpt to save the generated color palette table to a file via the output (H) argument. The 'H' setting in GMT upstream (see https://docs.generic-mapping-tools.org/latest/makecpt.html#h) is actually a flag to force the creation of an output (to stdout) in modern mode. Here we use it to set the filename too. See also GenericMappingTools/gmt#827 and GenericMappingTools/gmt#823 * Add truncate (G) alias for makecpt With rainbow cmap checks to test various zlow/zhigh combinations. * Add reverse (I) alias for makecpt Used 'earth' cmap to test various reversed colormap examples. * Alias continuous (Z) for makecpt Included one test to create a continuous cpt from blue to white. Also updated link to the full list of GMT's color palette tables due to documentation reorganization during GenericMappingTools/gmt#1594.

cpt = gmt.makecpt(C='jet', T=[mag.min(), mag.max()])
AttributeError: module 'gmt' has no attribute 'makecpt'
Python 3.6, GMT 6
Apparently the examples shown here: https://www.gmtpython.xyz/latest/design.html#the-gmt-python-api are not working. How do i generate a colorbar and a legend for my plot ? Is there a way to work directly with the gmt modules ?
