plotSetBar¶

Purpose¶

Sets the fill style and format of bars in a histogram or bar graph.

Format¶

plotSetBar(&myPlot, fillType, barStacked)¶

Parameters:

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

fillType (Nx1 vector) –

where N is the number of bar styles to set.

0	Solid, beveled edge
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

barStacked (Scalar) – 1 for stacked or 0 for side-by-side bars.

Examples¶

// Declare plotControl structure
struct plotControl myPlot;

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

// Set the first set of bars to have a solid-fill, the
// second set to have a fill of horizontal lines, the third
// to have a diagonal cross fill and set the bars to be
// side-by-side.
textures = { 0, 8, 13 };
plotSetBar(&myPlot, textures, 0);

// Create data
x = seqa(1, 1, 5);
y = {
1.5       2    1.8,
  2     2.1      3,
  3     2.5    3.6,
0.5     0.8      1,
  1     1.2    0.8
    };

// 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.
