Feb 18, 2021 · 1 You are passing a rasterio.dataset object, i.e. src to the show_hist function which is fine. But then you hit a MemoryError. This tells you that the array you are trying to load in memory (this is done under the hood by the show_hist function, see arr = source.read (masked=masked) in your traceback) is just too big in size to be allocated.

Rasterio also provides a show_hist () function for generating histograms of single or multiband rasters: >>> from rasterio.plot import show_hist >>> show_hist( ... src, bins=50, lw=0.0, stacked=False, alpha=0.3, ... histtype='stepfilled', title="Histogram") The show_hist () function also takes an ax argument to allow subplot configurations

There is a parameter for the 'title' but nothing for x_label and y_label. How to change it? For example, to "Valeur numérique" and "Fréquence". histogram customization rasterio Share
