VectorPlot2D

New in version 4.0

VectorPlot2D ( appearanceConst )

Argument Type Range Default Note
appearanceConst int 0..127 default
Description

The VectorPlot2D() function serves to draw two-dimensional vector plots. The 1st data series in the ChartData() function defines the x-values, the 2nd data series the y-values, the 3rd data series the vector lengths and the 4th data series the vector directions of the first series, the 5th, 6th, 7th and 8th data series in ChartData() the x-values, y-values, lengths and directions of the 2nd series, and so on. As for one-dimensional vector charts, symbols (appearance = symbol), shadow (appearance = shadow) and labels (appearance = label) can be added to the vectors by using the argument appearance. The options can be combined by using a plus sign "+". Rotating (appearance = horizontal) is not supported for two-dimensional plots as this is simply possible by switching the data series in ChartData() .
