DensityPlot(symbol+label;​9;​5;​1;​0.5)

DensityPlot(default;​25;​16)

Description

Two functions are available to set up density plots: DensityPlot() and DensityPlotOptions() . The appearance of the density can be controlled by the FillColorScale() functions, the labels by using the five style functions LabelTexts() , LabelStyle() , LabelBackground() , LabelBackgroundOptions() and LabelOptions() . By using the function BorderStyle() the appearance of the border around the density plot can be controlled.
