Frequently Asked Questions (FAQ)

Q1. How do I change the colormap?

To see all the available colormaps, such as "rainbow" or "AMIP", type the following into a cell in a Jupyter notebook within the JupyterLab interface.

vcs.listelements("colormap")

To change the colormap on your active canvas (the active image) type the following into a cell, then click on the "plot" button to replot the image/canvas.

canvas.setcolormap("rainbow")

Any command you've used when running a CDAT tool (like VCS) in a command line window can be used in Jupyter VCDAT. Just enter that command (like canvas.setcolormap("rainbow"))into a cell in a Jupyter Notebook within the VCDAT interface and press shift-enter to run that command.

Q2. Can I link to data that is not in the directory structure from which I launched JupyterLab?

If you want to access data outside of your top directory, you can create a symbolic link to the data. Details are described in the middle of the Using Your Own Data section of the Access Data wiki page.

You can’t perform that action at this time.
