Up to this point, we have limited our plots to two-dimensions and used the color scale to let the reader infer the intensity. Now that we have our data ready, lets start with 2 Dimensions first. Connect and share knowledge within a single location that is structured and easy to search. Pass a DataFrame to plot with indices as row/column labels: Use annot to represent the cell values with text: Control the annotations with a formatting string: Use a separate dataframe for the annotations: Set the colormap norm (data values corresponding to minimum and maximum points): Use methods on the matplotlib.axes.Axes object to tweak the plot: Copyright 2012-2022, Michael Waskom.
