Output Use Heatmap Function of Plotly to Create Heatmap in Python. We can also use the Heatmap function of plotly.graph_objects to create a heatmap of the given data. We must pass the x, y, and z-axis values inside the Heatmap function.. The z-axis values belong to the color of the heatmap. If we only pass the z-axis values, the other two axis values will be taken from the matrix indices.
