Hello I'm producing a series of different plots in eps format, which have the same aspect ratio but different values for the y-axis tic labels. I'd like to have them all with the same size, that is, that the plot itself has the same size, regardless of the width of the tic labels. I've tried adjusting the lmargin, but it seems to me there's a further scale change when the eps is produced, such that the width of the actual eps plot incl labels fits in the page. How's it possible to override this scale change?

Using the latest release 4.4.0-rc1:
set boxwidth 0.8 relative
set xdata time
set timefmt "%Y-%m"
set format x "%m\\n%Y"
set ylabel "label1"
set y2label "label2"
set ytics nomirror
set y2tics nomirror
set key off
set style fill solid 1.0
set boxwidth 0.9 relative
set style histogram clustered
set style data histograms
set style fill solid 1.0 border -1
plot "/tmp/file" using 2:xtic(1), "/tmp/file" using ($3+$4+$5+$6+$7)
axis x1y2
^
Need full using spec for x time data
(I understand that some of the settings may not be optimal. For example,
the boxwidth. I would expect to tune these once I see some output.)
A little searching hints that this message may be somewhat misleading.
That what it really means is that a "format" must be added. But perhaps
that hint is wrong? I've tried adding '%lf', '%lf-%lf', and '%lf-%lf
%lf' but the error persists.
Can anyone tell me the right way to generate this plot?

My code says, plot "/tmp/file" using 2:xtic(1), "/tmp/file" using ($3+$4+$5+$6+$7) axis x1y2 I've tried it without the :xtic(1) and still get the error. The help screen for "set style histogram" says, "Each element of the `plot` command must specify a single input data source (e.g. one column of the input file), possibly with associated tic values or key titles", so I have trouble understanding what additional using specifier I could add. The data file looks like this: 2009-01 1 1 0 0 0 0 2009-02 1 1 0 0 0 0 2009-03 3 9 0 0 0 0 2009-04 6 6 0 0 3 4 2009-05 11 14 3 3 0 4 2009-06 10 2 18 7 4 5 2009-07 12 18 31 7 6 13 2009-08 10 10 37 6 9 22 2009-09 14 25 45 8 13 24 2009-10 16 19 47 18 16 3 2009-11 14 24 29 7 6 3 I supposed I could drop the year and plot against the month -- for now. But this won't work once the file contains two more lines, as it will in little more than a month. Can you suggest the actual commands needed? Dave Close |

You already have too _few_ using specifiers to work with 'set xdata time'. Removing more obviously won't help with that. > The help screen for "set style histogram" says, "Each element of the > `plot` command must specify a single input data source (e.g. one > column of the input file), possibly with associated tic values or key > titles", so I have trouble understanding what additional using > specifier I could add. As I said, histogramming and date/time input don't make sense together. Drop the 'set xdata time' entirely and you should get a plot. |

At all. You will, of course, then, not see labels on your x-axis, but you should at least see a graph. Now, for those x-axis labels, Gnuplot's string functions are your friend: plot "/tmp/file" using 2:xtic(substr(stringcolumn(1),6,7)\\nsubstr(stringcolumn(1),1,4), "/tmp/file" using ($3+$4+$5+$6+$7) axis x1y2 should get you what you need. (I don't see this documented anywhere but Gnuplot's substring() function appears to use 1-based indexing.) |

I was in the process of researching how to get the labels I need when your note dramatically shortened my effort. But I did need to change your suggestion slightly. 1. Your parentheses weren't balanced (easy to fix). 2. \\n doesn't work in that place. I had to change it to '."\n".'. That is, put it in quotes and use string concatenation. I could also have used sprintf but that takes more characters to type. 3. I had to add "bmargin 3" so the second line of label would actually appear. Dave Close |

In my similar example I was able to take a substring of the date as a whole without needing to concatenate the pieces. If your source is a database query you might consider rewriting it if you can to avoid such ugliness. another trick for the x labels is set xtics nomirror out rotate by -45 which outputs the labels diagonally so you can squeeze more in. Don't know if that would work for you. Steve |
