DPlot supports antialiasing for line segments and symbols. This option is disabled if the display colour depth setting is 256 colours (8 bits per pixel) or fewer.
The antialias option will cause DPlot to take longer than normal to render a plot, particularly with 3D scatter plots and XY plots with many thousands of points or a thousand or more symbols. Also, you shouldn't use antialiasing for real-time plots in order to get the fastest possible screen update intervals.
You may also want to enable this option directly within Dplot by clicking on the "Options" menu and then choosing "General..". So, if you sometimes work with large data sets in XY plots but for all other graphs would like to keep antialiasing turned on, enter the maximum number of points for which you want to keep antialiasing in the For XY plots,... box. The default value of 5000 points generally works well.
The following command turns on antialiasing:
Dummy=FNDplot_send_cmd("[GeneralOptions(32,32)]") ! enable antialiasing
The following command turns off antialiasing:
Dummy=FNDplot_send_cmd("[GeneralOptions(32,0)]") ! disable antialiasing
