Re: Scaling of surface plots

[Keith, T. <ke...@um...>]

Consider something like this ...

*****

Let minX and maxX be the minimum and maximum value, respectively, of =
your data along the x-Axis

Let minY and maxY be the minimum and maximum value, respectively, of =
your data along the y-Axis

Let minZ and maxZ be the minimum and maximum value, respectively, of =
your data along the z-Axis

*****

double rangeX =3D fabs(maxX - minX);

double rangeY =3D fabs(maxY - minY);

double rangeZ =3D fabs(maxZ - minZ);

double maxRange =3D rangeX;

if (rangeY > maxRange) maxRange =3D rangeY;

if (rangeZ > maxRange) maxRange =3D rangeZ;

double scaleX =3D maxRange / rangeX;

double scaleY =3D maxRange / rangeY;

double scaleZ =3D maxRange / rangeZ;

double maxScale =3D scaleX;

if (scaleY > maxScale) maxScale =3D scaleY;

if (scaleZ > maxScale) maxScale =3D scaleZ;

setScale(scaleX, scaleY, scaleZ);
