Plotting multiple lines with difference specific colours via plot function

Question

0 个投票

Is there any way to use the plot function to plot multiple lines, each having a specific colour?

e.g plot(x1,y1,'-','color',[0 0 1],x2,y2, '-', 'color',[1 0.4 0.6])

This doesn't work, but is there any way of properly doing this?

You can't combine everything into one single plot function.

What you can do is combine different plots via using hold on/off

E.g plot(x1,y1,'-','color',[0 0 1]) hold on plot(x2,y2, '-', 'color', [1 0.4 0.6]) hold off

"You can't combine everything into one single plot function." Really?

See my answer for the correct way of doing this without requiring multiple plot calls.

You just need to set the line ColorOrder property of the axes, then you just need one plot call:

>> map = [0,0,1;1,0.4,0.6];
>> axes('ColorOrder',map,'NextPlot','replacechildren')
>> plot([0,1],[1,2],'-',[0,1],[2,1],'*-')
