plotSetGrid¶

Purpose¶

Controls the settings for the background grid of a plot.

Format¶

plotSetGrid(&myPlot, tickStyle[, color])¶

plotSetGrid(&myPlot, onOff)

Parameters:

&myPlot (struct pointer) – A plotControl structure pointer.
tickStyle (string) – specifies whether grid marks should be drawn on major tick marks. Options: ["major", "minor", "both"].
color (string) – Optional argument, name or rgb value of the new color.
onOff (string) – turns the grid on or off. Options: ["on", "off"]. If used, this must be the only argument passed to the function besides the plotControl structure pointer.

Examples¶

// Declare plotControl structure
struct plotControl myPlot;

// Initialize plotControl structure
myPlot = plotGetDefaults("scatter");

// Set grid to be black and on the major ticks only
plotSetGrid(&myPlot, "major", "black");

// Create a scatter plot of random data
plotScatter(myPlot, seqa(1, 1, 10 ), rndn(10, 1));

Remarks¶

In most cases, plotsetgridpen() is preferrred over plotsetgrid().

Note

This function sets an attribute in a plotControl structure. It does not affect an existing graph, or a new graph drawn using the default settings that are accessible from the Tools > Preferences > Graphics menu.
