MATLAB: Empty Figures because of empty variables

figureMATLABvariables

Hello, I made a code to create time series et climatological graphics but my figure remain empty, I've noticed that I have some of my matrix how are filled with "NaN" but i don't really know where the problem come from, or at least how to fix it… Here is the code : (titles are in french sorry for that)

PIX_MENS, CLIMATO_PIX and DISP_PIX are empty as well as MAT_PIX where only the third variable of the table is empty. They are all needed to plot to graph but I have no clue about how to fix the problem…
If anyone can help me…
Have a good day,

It's all right I've found the solution, I just needed to do a table2array on MAT_YEAR so I could use the operator "==".
Thanks for your help and if you have any idea to simplify the code I would be glad to ear it!
Have a good day!
