matplot: pcolor

2D pseudo color plot (function pcolor)

Code:

// load the peaks sample data
peaks = matplot.peaks();

// make a figure of size 700 x 500 pixels
fig = new matplot.Figure("plot",700,500);

// add axis to the figure
ax = fig.axes();

// pseudo color plot
ax.pcolor(peaks.x,peaks.y,peaks.z);

// add color-bar
ax.colorbar();

// draw everything
fig.draw();
