Question: Moisture Uptake Code about pysplit HOT 2 CLOSED

It would be awesome if graduated color lines could be done in matplotlib- edit: apparently this is possible, but with a LineCollection of line segments, each with its own color- I approximate with scatter plots. I just posted a basic scatter plotting/more advanced MapDesign example, which shows two different methods of scatter plotting- one using basemap.scatter() and the other using pysplit.traj_scatter(), which is the new and improved version of pysplit.map_data_scatter() that you read about. This doesn't directly answer your question yet of how to plot moisture uptakes (Trajectory.uptake) , which can be slightly more complicated than just plotting the basic along-trajectory data in Trajectory.data, but it'll get you going on the right track. I'm still working on the more advanced scatter plotting examples.

As a general commentary/feedback, in your example code you are making a series of floats that you then use to pick 65 colors from the Blues colormap. The colors of your trajectories represent their order in trajgroup, not meteorological or uptake information. Basic path plotting/color coding is available as an example, as is integration error calculation (and if necessary, there is information on reverse trajectory generation and loading), and rainstatus merely indicates which existing trajectories produce rain within a certain range of time 0. Also, that's a very creative but unintended way to create a Basemap using PySPLIT. In fact, you're not actually using PySPLIT except as a sort of middleman- you're calling matplotlib Basemap through the mapdesigner module, which imports Basemap. I suggest having a look at the examples to see how MapDesign is ideally used.

Hope this helps!

Mellissa,

This helps a great deal. Thank you so much again for your feedback. I have been going through some literature review, and can see how much more complex the moisture uptake calculation can be versus basic along trajectory data. I will take a crack at working with the along traj data for now and probably have more questions for you after that... :-)

Thanks again. I really appreciate your time. Looking forward to your more advanced scatter plotting examples.

Best,
Maria
