The function “lines” give you the default MATLAB line colors. In the above example, if you type

ColorSet = lines(50);


it will give you the default colors. However, “lines” only give you 7 distinct colors, and it simply repeats itself after that.

How do you call out the colors from the color map and apply them to individual plots?

For example, say I wanted to use color 10 from the colorbar generated from the code below. How could I put it in my plot command? Is it done just like calling out the default colors?

I know I could just use one of the default colors but I have 12 plots that require different colors for my project.

NumberOfPlots=12;

ColorSet=varycolor(NumberOfPlots);

figure
hold on;

for m=1:NumberOfPlots
plot(ones(20,1)*m,’Color’,ColorSet(m,:))
end
set(gcf, ‘Colormap’, ColorSet);
colorbar

plot(x,y,’?')

thank you very much

Did you download “varycolor” from the File Exchange? Also, make sure that you put the function at a location where MATLAB can find it. Read about it here.

i have a cell array z{k}, i want to plot it with different colours, i tried ur code, but its not working please help me.

ColorSet = varycolor(280);

set(gca, ‘ColorOrder’, ColorSet);
plot(z{k})
hold on

when i tried this, i am getting error like this

??? Undefined function or method ‘varycolor’ for input
arguments of type ‘double’.

Geoffrey: I haven’t seen your code but my guess is that you’re setting the color order and then calling plot().

The problem with this is that plot() resets the ColorOrder property. You can prevent that by preceding plot() with a command that freezes ColorOrder. Either like this:

  set(gca, 'ColorOrder', colororder);
  hold on
  plot(...)

or like this:

  set(gca, 'ColorOrder', colororder);
  set(gca,'NextPlot','replacechildren')
  plot(...)
