SET_XY Procedure
Standard Library procedure that sets the default data axis range for either the x- or y-axis. It should only be used for emulating Version 1 of PV‑WAVE.
Usage
SET_XY, xmin, xmax[, ymin, ymax]
Input Parameters
xmin—The minimum default value for the x-axis.
xmax—The maximum default value for the x-axis.
ymin—(optional) The minimum default value for the y-axis.
ymax—(optional) The maximum default value for the y-axis.
Keywords
None.
Discussion
SET_XY is used for setting the range of data values that will be drawn in the rectangular display window. (Normally the axis range is determined automatically by scanning the data.)
You should only use SET_XY if you are trying to emulate Version 1 of PV‑WAVE. With more recent versions of PV‑WAVE, you should use the system variables !X.Range and !Y.Range, or their corresponding keywords.
note | SET_XY sets the Range, Crange, and S (scaling) fields of the system variables !X and !Y. This may cause subsequent plots of otherwise familiar data to appear skewed. |
Example
PLOT, [12, 26, 35, 44], [50, 43, 89, 70]
WAIT, 1
PLOT, [12, 26, 35, 44], [50, 43, 89, 70], $
XRange=[10, 50], YRange=[40, 100]
WAIT, 1
SET_XY, 10, 50, 40, 100
PLOT, [12, 26, 35, 44], [50, 43, 89, 70]
