# ztics¶

## Purpose¶

Sets and fixes scaling, axes numbering and tick marks for the Z axis.

Note

This function is for the deprecated PQG graphics.

pgraph

## Format¶

ztics(min, max, step, minordiv)
Parameters
• min (scalar) – the minimum value.

• max (scalar) – the maximum value.

• step (scalar) – the value between major tick marks.

• minordiv (scalar) – the number of minor subdivisions. If this function is used with contour(), contour labels will be placed every minordiv levels. If 0, there will be no labels.

## Remarks¶

This routine fixes the scaling for all subsequent graphs until graphset() is called.

This gives you direct control over the axes endpoints and tick marks. If ztics() is called after a call to scale3d(), it will override scale3d().
