I have an array storing pressure coefficient values for each triangular face from a 3D geometry, and I am trying to obtain the RGB index values from a jet colormap based on the min and max from this array. I have done this on Matlab like this where cvar is the array storing the values. How can I achieve this

Pyplot imshow incorrectly output black to white
I want to plot some letters and separate them by 4 equal zones according to the letter’s width and height. It just so happens that everything looks good until a zone has blank pixels, such as zone_0.jpg, zone_7 and zone_12 as seen in the images below. How can I make it so that the image box that have 255 for
How to use colormap in subplots?
For a project, I’m trying to plot on the same figure (using subplots) to “graph”. The data have been collected using a database (but for my problem here, I tried to selected only reasonable number of value). On the left of the figure, I plot the temperature in JFK during 10 consecutive days whereas on the right, I plot a
Seaborn scatter plot from pandas dataframe colours based on third column
I have a pandas dataframe, with columns ‘groupname’, ‘result’, and ‘temperature’. I’ve plotted a Seaborn swarmplot, where x=’groupname’ and y=’result’, which shows the results data separated into the groups. What I also want to do is to colour the markers according to their temperature, using a colormap, so that for example the coldest are blue and hottest red. Plotting the
