./plotter zline.pro
zline |
This procedure toggles a flag to draw a horizontal line on the plot at the zero level. Use the /on or /off keywords to ensure that the zero line plot is on or off (otherwise it simply toggles the state).
If both /on and /off are used at the same time, an error message is printed and the state of the zero line is not changed.
Keywords | |
on |
Turn the zero line on. |
off |
Turn the zero line off. |
