Description: | Resolution Command: Specifies the resolution of mathematical and statistical plots, where the | |||||
| resolution is the interval between values of the independent variable used to generate the plot. | |||||
| A real number ninterval specifies the interval in user units. A binary integer #ninterval specifies the | |||||
| interval in pixels. |
|
|
| ||
| The resolution is stored as the fourth item in PPAR, with default value 0. The interpretation of | |||||
| the default value is summarized in the following table. | |||||
