#2621 — Reading pattern from a column...

I am using gnuplot 4.6 on ubuntu linux.

I am plotting a histogram but I want the bars to have different fill styles. I have added one column of data (0,1,2,3,4 etc.) and I am trying to using the plot command as:

plot 'kk.csv' usi 9:xtic(1) with boxes fillstyle pattern $10

As you have guessed, it is not not working; it says ; expected.

Please tell me what I am doing wrong?

I think you want something similar to

	plot $data usi 0:1:(.5):2:xtic(3) with boxes lc variable

only the pattern should change instead of the colour (which is taken
here from column 2)?

($data is a new inline data variant in gp5.0, just replace it with your
file name)

The keyword "variable" unfortunately is not implemented for fillstyles,
so i´m not sure it is possible to take the fillstyle from a column.

As there are not so many patterns available anyway, you could however do
this (pattern in column 2 again):

plot for [i=1:5] $data us ($2==i ? $0 : NaN):1:(.5):xtic(3) \
	with boxes fillst pattern i

i.e. cycle though the patterns and eacht time only plot the data in rows
where $2 matches.

Thanks a lot! That did it. Although I am getting a lot of warning, but the result is what I wanted.

You mean these

	 warning: add_tic_user: list sort error

? Yes, i get those too. I say they´re harmless, but you might want to
check if all tics are labeled correctly.
