Fill
Background Color: change the color of the report background, without affecting the chart background. This function is available for both tree maps and hierarchical tree maps.
Settings
Scale to Fit: when the trellised chart is larger than the canvas, you can scale it down to fit the canvas.
Optimize Visual: the visual optimization engine in Pyramid is a heuristic that automatically redacts certain parts of a graphical visualization based on the amount of space provided.
