The plotgrid function creates an iso-line, iso-colour or false-colour plot for a given meshgrid and the according data. The function also extrapolates data outside the mesh.
See also: egrid, plotisolines, plotisocolours, plotfalsecolours
Usage:
plotgrid(x,y,Y,mode,clabel,climits)
Where:
| Parameter | Description |
x and y | Are the coordinate matrices of the mesh grid, see egrid. |
Y | Is the to be plotted quantity distribution in matrix form. |
mode | Specifies the plot mode: ‘isocolor’ for iso-colour plot ‘falsecolor’ for false-colour plot ‘lines’ for iso-line plot (default) |
clabel | Defines the colourbar label in colour mode, string or char. |
| climits (optiona) | Specifies the colourbar limits in vector format in colour mode: [c1 c2] |
Examples
Plot illuminance measurement data for a grid determined by the egrid function:
[x,y] = egrid(2,3);
E = [65.0451 65.4281 66.6292 67.1130 66.7063
