11.21 Sample ‘colorbar’ ¶

Example of colorbar position and styles.

MGL code:

call 'prepare2d'
new v 9 'x'
subplot 2 2 0:title 'Colorbar out of box':box
colorbar '<':colorbar '>':colorbar '_':colorbar '^'
subplot 2 2 1:title 'Colorbar near box':box
colorbar '<I':colorbar '>I':colorbar '_I':colorbar '^I'
subplot 2 2 2:title 'manual colors':box:contd v a
colorbar v '<':colorbar v '>':colorbar v '_':colorbar v '^'
subplot 2 2 3:title '':text -0.5 1.55 'Color positions' ':C' -2
colorbar 'bwr>' 0.25 0:text -0.9 1.2 'Default'
colorbar 'b{w,0.3}r>' 0.5 0:text -0.1 1.2 'Manual'
crange 0.01 1e3
colorbar '>' 0.75 0:text 0.65 1.2 'Normal scale':colorbar '>':text 1.35 1.2 'Log scale'

C++ code:

	gr->Box();	gr->ContD(v,a);
	gr->Colorbar(v,"<");	gr->Colorbar(v,">");	gr->Colorbar(v,"_");	gr->Colorbar(v,"^");

	gr->SubPlot(2,2,3);	gr->Title(" ");
