A TScatter is able to draw four variables scatter plot on a single plot.
The two first variables are the x and y position of the markers, the third is mapped on the current color map and the fourth on the marker size.
The following example demonstrates how it works:
TScatter can be drawn with the following options:
Option | Description |
---|---|
"A" | Produce a new plot with Axis around the graph |
