3D surface plots in GAUSS 19 : any suggestions for plotSetZRange?

Question

I want to compare two similar surface plots and therefore need to have a similar minimum and maximum for the Z-axis. plotSetZRange is not available! Other suggestions?

You can directly set the zAxis.axisRange member of the plotControl structure. Here is a simple example.

 x = seqa(1,1,5);
y = seqa(1,1,6);
 
z = { 3 3 2 4 5 4,
      3 3 2 3 4 5,
      4 3 2 2 4 4,
      4 4 3 3 5 6,
      5 6 4 4 6 7 };
 
Sigma = 1;
GridFactor = 3;
 
{ xx,yy,zz } = spline(x,y,z,Sigma,GridFactor);
 
struct plotControl myplot;
myplot = plotGetDefaults("surface");
 
// Set the Z-axis range to be from -2 to +15
myPlot.zAxis.axisRange = -2|15;
 
plotsurface(myPlot, xx',yy,zz');

	x = seqa(1,1,5);
	y = seqa(1,1,6);

	z = { 3 3 2 4 5 4,
	3 3 2 3 4 5,
	4 3 2 2 4 4,
	4 4 3 3 5 6,
	5 6 4 4 6 7 };

	Sigma = 1;
	GridFactor = 3;

	{ xx,yy,zz } = spline(x,y,z,Sigma,GridFactor);

	struct plotControl myplot;
	myplot = plotGetDefaults("surface");

	// Set the Z-axis range to be from -2 to +15
	myPlot.zAxis.axisRange = -2\|15;

	plotsurface(myPlot, xx',yy,zz');
