Stack Diagram: 

This operation takes a real number from the top of the stack and interprets that number as the "resolution" to use in a future plot. It stores that information in the plot parameters, found in a variable called PPAR in the current directory. The existing resolution which may be specified in an existing PPAR variable will be changed and then PPAR is stored, replacing the old value. If PPAR did not exist prior to executing these operations, a new PPAR variable is created. Its contents will be defaults except for the resolution which is specified from the stack.

The default resolution is 1 which means that each pixel in the plot view should be calculated when plotting an equation. Increasing this value to 2 will cause the calculator to evaluate the equation for every other pixel. Higher values reduce the resolution even further but increase the performance of the plot.
