plotSetFill¶

Purpose¶

Sets the fill style, transparency and color for area plots, histograms and bar graphs.

Format¶

plotSetFill(&myPlot, fillType[, opacity_pct[, colors]])¶

Parameters:

&myPlot (struct pointer) – A plotControl structure pointer.

fillType (Nx1 vector) –

vector where N is the number of bar styles to set.

0	No fill
1	Solid
2	Dense 1
3	Dense 2
4	Dense 3
5	Dense 4
6	Dense 5
7	Dense 6
8	Horizontal lines
9	Vertical lines
10	Cross pattern
11	B diagonal pattern
12	F diagonal pattern
13	Diagonal Cross

opacity_pct (scalar) – Optional argument, between 0 and 1. The percent opacity of the fill.
colors (string array) – Optional argument, color names or HTML hex value colors.

Examples¶

// Declare plotControl structure
struct plotControl myPlot;

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

// Set all bars to have a solid, blue, fill, with 50% opacity
textures = 1;
plotSetFill(&myPlot, textures, 0.5, "blue");

// Create data
x = seqa(1, 1, 5);
y = { 1.5, 2, 3, 0.5, 1 };

// Draw bar graph
plotBar(myPlot, x, y);

Remarks¶

When graphing without the use of a plotControl structure, these settings may be chosen through the Tools > Preferences > Graphics menu, after selecting the Bar radio button. See the GAUSS Graphics chapter for more information on the methods available for customizing your graphs.
