scale

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.

Library

pgraph

Format

scale(x, y)
Parameters:

  • x (matrix) – the x-axis data.

  • y (matrix) – the y-axis data.

Remarks

x and y 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 and ytics whenever it is called.

If either 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 or ytics. If xtics or ytics have been called after scale, they will override scale.
