| DefinePlot |
|
| pID | - | The plot iD being defined |
| wID | - | The window iD with which pID is associated. |
| gX | - | An optional input that specifies the the number of grids across the X axis of the plot. This is defaulted to -1 which is sets the number of grids to the number of pixels across the plot. The value is used when auto plotting from a defined grid of variables. |
| gY | - | An optional input that specifies the the number of grids across the Y axis of the plot. This is defaulted to -1 which is sets the number of grids to the number of pixels across the plot. The value is used when auto plotting from a defined grid of variables. |
| TmAxis | - | A optional input that specifies which if any of the plot axes are time based. The default value is set to NONE. To specify that the X axis is time based set to X. To specify that the Y axis is time based set to Y. |
| TmB | - | A optional input that specifies the time of the first pixel in on a time based axis. The default value is -1 which assumes that TmAxis has be set to NONE. The time is input as a list of the form [Year, Day, Hour, Minute, Second, Millisecond]. |
| TmE | - | A optional input that specifies the time of the last pixel in on a time based axis. The default value is -1 which assumes that TmAxis has be set to NONE. The time is input as a list of the form [Year, Day, Hour, Minute, Second, Millisecond]. |
The routine assumes that the plot being defined is a CARTESIAN plot. If this is not the case the plot format should be set prior to invoking DefinePlot by calling PLTinfoChg and setting the AXIS FORMAT. DefinePlot sets all plot variables which have not previously been set to reasonable default values based in the current plot format. These can be changed at anytime prior to usage (generally in a call to PlotOutlines).
