The command FUN2 allows to plot 2D functions and fill an histogram. The variables names are X and Y .
It is possible to represent a 2D histogram in several ways :
1. As a scatter plot.
2. With proportional boxes.
3. With a color table.
4. As a surface plot.
5. As a surface with color levels.
6. As a surface with a contour plot on top.
7. As a surface with Gouraud shading.
8. As a lego plot.
9. As a lego plot with colours or shading.
10. As a line contour plot.
11. As a table.
12. As an arrows plot.
