scale3d#

Purpose#

Fixes the scaling for subsequent graphs. The axes endpoints and increments are computed as a best guess based on the data passed to it.

Note

This function is for use with the deprecated PQG graphics.

Format#

scale3d(x, y, z)#
Parameters:

  • x (matrix) – the x-axis data.

  • y (matrix) – the y-axis data.

  • z (matrix) – the z-axis data.

Library#

pgraph

Remarks#

x, y and z must each have at least 2 elements. Only the minimum and maximum values are necessary.

This routine fixes the scaling for all subsequent graphs until graphset() is called. This also clears xtics, ytics and ztics whenever it is called.

If any of the arguments is a scalar missing, the main graphics function will set the scaling for that axis using the actual data.

If an argument has 2 elements, the first will be used for the minimum and the last will be used for the maximum.

If an argument has 2 elements, and contains a missing value, that end of the axis will be scaled from the data by the main graphics function.

If you want direct control over the axes endpoints and tick marks, use xtics, ytics, or ztics. If one of these functions have been called, they will override scale3d.
