Describe the feature:
Ideally, the heatmap should include an option for a "full grid" view, which also draws the grid on blank returns. Right now it only draws a box around valid values.
Additionally, an option to show "-" or 0 when there are no returns for a category would be very useful.
Describe a specific use case for the feature:
Many users have claimed it makes it hard to visualize which value belongs to which category without a grid, specially if values are concentrated on the upper right hand side of the chart (assuming a left Y axis and a bottom X axis)
