changing color and x-axis ticks in barplot

Hi

I'm making a barplot of some tests results, but on the x-axis the standard format uses 1-2-3-4 etc. However, I want to replace these ticks by text.

Furthermore, I want to give the different bars different colors. Is this possible?

Thanks!

JW, try this:

h = bar(rand(1,3))
set(gca,'XTickLabel',{'One','Two','Three'})

Setting different colours for each bar is a little tricky because bar() makes the bars as a group (with a consistent colour), but can be done to each bar separately using the faceVertexCData property as follows:

barGrpH = get(h,'Children');
myCols = lines(3);
set(barGrpH ,'FaceVertexCData',myCols)

Thanks!

I used exactly the same, but 'XTick' instead of xticklabel.. stupid mistake..

Do you also know how to give each bar a different color?

Yep, the answer has a second part which sets the colour independently. The command lines(3) makes a set of 3 1-by-3 RGB colours that just happen to be be blue, green, red. You can insert any RGB colours you like here.

I indeed overlooked the second part of your answer, thanks for your help!

No problems JW... I actually only wrote the first part first, then updated 10 minutes later... a bit sneaky :)
