| Syntax C/C++ | #include <Mgraph.h>
void M_findDensityMapBounds( extended xmin, extended xmax, extended ymin, extended ymax, extended zmin, extended zmax, COLORREF mincolor, COLORREF maxcolor ); |
| Pascal/Delphi | uses Mgraph;
procedure M_findDensityMapBounds( xmin, xmax, ymin, ymax, zmin, zmax: Extended; mincolor, maxcolor: COLORREF ); |
|
| Description | Similarly to the function V_findAxes for X-Y vector plots, this function calculates a color scale from the parameters mincolor, maxcolor, zmin and zmax, and prepares an X-Y coordinate system for color-density plots of matrices. If necessary, the x and y ranges are slightly enlarged so as to ensure that the grid-lines correspond to exact (rather than only rounded) values. If zero falls into either or both ranges, it will fall onto a grid line.
The user will rarely call this function himself. It is internally called by all functions of the MF_xyzAutoDensityMap and MF_zAutoDensityMap families. |
