plot using with characters which are cell and numeric data.

data=[1;2;3;4;5;6];
ids={'12.1a';'1.2b';'1.3c';'1.4d';'1.7e';'1.8f'}

%I wanna plot the data and ids like, plot(ids,data,'b') but Conversion to double from cell is not possible error occurs.

%How I can handle this cellarray for plot?

data=[1;2;3;4;5;6]
ids={'12.1a';'1.2b';'1.3c';'1.4d';'1.7e';'1.8f'}
plot(data,'b')
set(gca,'XTick',1:numel(ids))
set(gca,'XTickLabel',ids)

Thank you for your answer. I need to rotate ids (to write vertically), how can I do that?

[sermet]

sometimes ids would be very large (hundreds) so they cannot be easily readable.

If you have the latest version of Matlab add this

h=gca,
h. XTickLabelRotation=90

If not, reduce the number of ticks

ids={'12.1a';'1.2b';'1.3c';'1.4d';'1.7e';'1.8f'}
data=1:24
ids=repmat({'12.1a';'1.2b';'1.3c';'1.4d';'1.7e';'1.8f'},4,1)
plot(data,'b')
NumTick=8  % number of ticks
xticks=linspace(1,numel(data),NumTick)
set(gca,'XTick',xticks)
set(gca,'XTickLabel',ids)

I downloaded Rotate Tick Label and applied it. It worked well but I'm still having difficulty for scale. Hunderds of ids seem very close. Can I seperate them a little bit to reading more easily?
