| Argument | Type | Range | Default | Note |
|---|---|---|---|---|
| appearanceConst | int | 0..127 | default | |
| numOfGridPointsHorizontal | int | 2..100000 | (autom.) | |
| numOfGridPointsVertical | int | 2..100000 | (autom.) | |
| arrangeColumnByColumn | int | 0..1 | off | |

Examples
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.
