The images below (except the isosurface) are generated using the following model:

fsin(x[2], a[1]){
d=x[1]^2+x[2]^2;
fsin = sin(d)*exp(-sqrt(d));
}

The table below shows the available image types and corresponding assignement of coordinates X Assign and function F Assign. Click on an image below to get its larger size version.

	Plot y=f(x,c) x[1] → X axis x[2] → 0 f → Y axis		Group plot y=f(x,ci) x[1] → X axis x[2] → Group value f → Y axis
	Contour line f(x,y)=c x[1] → X axis x[2] → Y axis f → 0		Contour map f(x,y)=ci x[1] → X axis x[2] → Y axis f → Group value
	Surface z=f(x,y) x[1] → X axis x[2] → Y axis f → Z axis		Isosurface f(x,y,z)=c x[1] → X axis x[2] → Y axis x[3] → Z axis f → 0 (see model below)

The isosurface above is generated using the model:

torus(x[3], a[1]){
array center[3];
center = [0, 0, 0];
torus = hfTorusY(x,center,7,3);
}

The above image types can be time-dependent with using mapping of an additional coordinate to a Time variable.
For example, for the model:

fsin(x[3], a[1]){
d=x[1]^2+x[2]^2;
fsin = sin(d+x[3])*exp(-sqrt(d));
}

• Define a time-dependent plot y=f(x,t):
  x[1] → X axis
  x[2] → 0
  x[3] → T1 time variable
  f → Y axis
• Define the Time Curve for x[3]
