I am trying to create a Contour Plot containing the values: Date/Waterdepth/Temperature. The table looks like that in Excel, were blue=depth, orange=dates and green=temperature:
Here is my code and the error I receive:
data = readtable('temperatur.xls','Range','A1:H21'); x = data(2:end,1); y = data(1,2:end); z = data(2:end,2:end); contourf(x, y, z);
It appears to me that Matlab has an issue with the date-time format. I have tried to use numerous different date formats but could not get it to work. The XLS file is attached to this question. Any help is very much appreciated!
