The pictorial stacked chart is an improved variation of a column or bar chart. Use an image related to the topic, natively plotly does not implement a similar graph but here I propose an example of how to do it with SVG files from Free Icons | Font Awesome

if (np.any(matrix[x,:,:])):
for y in range(matrix.shape[1]):
if (np.any(matrix[x][y])):
if x>=matrix.shape[0]*start and x < matrix.shape[0]*end:
matrix[x][y] = [color_rgb[0],color_rgb[1],color_rgb[2],list(matrix[x][y])[-1]]
return matrix
