Colors for discrete ranges in heatmaps

Hi @jayeetamukherjee, Your case needs the min&max of the subset of negative, respectively positive values: import plotly.graph_objects as go import numpy as np def three_colorscale(z, colors): if len(colors) !=3: raise ValueError("") neg=z[np.where(z<0)] pos=z[np.where(z>0)] a, c = neg.min(), neg.max() d, b = pos.min(), pos.max() bvals= [a, c/2, d/2, b] nvals = [(v-bvals[0])/(bvals[-1]-bvals[0]) for v in bvals] dcolorscale = [] for k in range…
