I try to put the space to the index in the letters of the labels of Gnuplot. I use the following command:
set terminal pngcairo size 500,400 enhanced font 'Verdana,10'
set output 'test.png'
set xlabel 'atan(~{/Symbol w}{.6\~}_2)'
set ylabel 'atan(~{/Symbol w}{.6\~}_2)'
plot sin(x)
As you can see from the plot here the _2 over-plot the symbol. Could someone help me to understand how to put extra space to the indexes?
Admittedly, this is a bit of a hacky solution but it seems to work:
set xlabel 'atan(~{/Symbol w}{.6\~} _2)'
set ylabel 'atan(~{/Symbol w}{.6\~} _2)'
Adding the space after the symbol means that the subscript 2 doesn't overlap with it:

Can you tell us how to make the chart with all headings and captions fit into the fixed vertical size and the horizontal size is floating?
If I set small fixed image sizes, some axes captions disappear, and if I set large fixed image sizes, then there is an empty space on the sides.
And I want you to be able to specify the height of the image and gnuplot will determine for itself what its width must be to fit everything you need.
For example (margin - empty space, but on the right, the inscription didn't fit:
set terminal pngcairo notransparent enhanced font "Calibri, 15" fontscale 1.0 size 800, 800; set zeroaxis;
Apparently, gnuplot does not automatically provide enough space for long numbers in the colorbox.
Since you have a logarithmic scale from 0.0000001 to 0.1, you might want to consider to display your numbers in a different format, i.e. from 10^-7 to 10^-1.
Code:
### no long numbers in colorbox
reset session
set colorbox
set palette rgb 33,13,10
set xrange [-7:-1]
set cbrange [1e-7:0.1]
set logscale cb
set format cb "10^{%T}"
plot '+' u 1:1:(10**$1) w l lw 3 palette z notitle

I wrote a script to get graphs similar to this one, using gnuplot:
How do I add some empty space at the beginning of the x-axis and y-axis? I want something like the following graph:
You have several options. #Christof links you to one that uses offsets. Also, presuming you set the xtics (you should include your code as that helps us help you), you can set the xrange to just miss the next tics. For example, assuming you set xtics 0.05, you can:
set xrange [-0.351:0.149]
This is a quick and easy way to give yourself a little whitespace. Notice it does not quite reach the next ticmark.
Alternatively, you can directly set xrange and yrange as big as you want, then specify in this order, a start location, an increment, and an end location for the tic marks:
set xrange [-0.4:.2]
set xtics -0.3,0.05,0.1
I'm trying to use multiplot to overlay a curve over a contour map, and here is my gnuplot script.
set term postscript enhanced color 'Times-Roman,24'
set output 'cimax_pmf.eps'
set encoding iso_8859_1
set nokey
set xlabel 'RC(\305)'
set xrange [0:12]
set yrange [0.2:1]
set ylabel 'c^2_{imax}'
set y2label 'PMF (kcal/mol)'
set y2range [-20:1]
set multiplot
set pm3d map interpolate 10,10
set view map
set isosamples 10 #increase resolution
set palette rgb 33,13,10 #rainbow color scheme
unset colorbox
splot[0:12][0.2:1] 'cisq_rrr_reduced.dat' u 1:2:3 notitle
unset map
plot[0:12] 'final_pmf.dat' u 1:2 w line lt 2 lw 2 notitle axis x1y2
unset multiplot
One thing to mention is that I have two vertical y axis, as suggested by "axis x1y2" in my script. The problem is that after running this script, I found that the second plot does not align with the first plot correctly. In other words, they have different sizes and their overlap seems to be problematic. It looks like the problem described in the first figure of this page
http://lowrank.net/gnuplot/plot3-e.html#5.10
But I cannot solve this problem by using the script similar to that page.
Thanks.
I am more familiar with multiple plots in or next to each other, but nevertheless two things might help you:
multiplot allows for "set size" command (see "help set size" for more info) to be used for each graph. But I guess if you say the script on the Not So FAQ page did not help, this is probably not enough.
It might therefore be useful to set margins (see "help set margin"), which can be used to align more precisely graphs in a multiplot. It also quite often fixes the problem of data ranges of different lengths that cause numerous misalignment problems.
I would suggest not to use pm3d and multiplot at all and instead use plot … with image. This way, you can do with a single plot command.
If I did not make any mistakes, just change your code to (everything before multiplot is unchanged):
[…]
set y2range [-20:1]
set palette rgb 33,13,10 #rainbow color scheme
unset colorbox
plot\
'cisq_rrr_reduced.dat' w image notitle,\
'final_pmf.dat' u 1:2 w line lt 2 lw 2 notitle axis x1y2
You can use gnuplot's feature of saving contour data to a file via set table (see documentation, and rather implicit example here). Something like:
...
set table 'contours.dat'
splot[0:12][0.2:1] 'cisq_rrr_reduced.dat' u 1:2:3 notitle
unset table
plot[0:12] 'final_pmf.dat' u 1:2 w line lt 2 lw 2 notitle axis x1y2, \
'contours.dat' using 1:2
Adjust for your case.
Okay I have been working with gnuplot for sometime and have one question. I cannot make the plot size equal to the terminal size I set it to. There are examples of setting
Lmargin,rmargin, tmargin and bmargin to 0 but this doesn't work on 'splot' which is 3d plotting. So I want to know what is the workaround for it?
For color maps you can use plot ... with image instead of set pm3d map if you want to use the margin options as usual. For 3d plots, as you say, the margin options are not available, and a workaround would be to shift the position of your graph and scale it. To do that, use set origin and set size respectively.
For instance, splot x*y yields the following:
If you want to reduce the margins while keeping the same overall terminal size, you can try:
set origin -0.1,-0.1
set size 1.2,1.2
splot x*y
which gives you:
You probably get the idea. Note I set a background color just so you can visualize where the margins lie because of the white background in the Stack Overflow website.
I use the following gnuplot script in order to plot a data file
reset
unset key
set size 1,1
set xrange [-10.1:11]
set yrange [-45:45]
set xlabel 'x'
set lmargin 6
set label 1 "~x{0.7.}" font "Helvetica, 20" at graph -0.1, graph 0.5
set xtics 2
set ytics 15
set mxtics 5
set mytics 5
plot "pss_data.dat" u 1:2 w dots lc rgb 'black'
set term postscript eps enhanced "Helvetica" 20 size 7in, 5in
set output 'plot.eps'
replot
reset
set terminal windows
quit
The exported .eps file is the following.
Well, in fact this is the corresponding .pdf file using Adobe Acrobat XI in order to make the conversion. However, the .pdf output contains not only the plot but all the unwanted black area above it! In an attempt to get rid off the white area I used the command line
epstopdf plot.eps
The output is the following
Now, the white area has been removed but the label at the y axis is also missing!
Any ideas? I want to have in a .pdf file only the plot (without the above white area) but with the label at the y axis.
Many thanks in advance.
Your bounding box may be incorrectly set. You can try using epstool on the eps you create:
epstool --bbox myeps.eps myneweps.eps
That should calculate the bounding box correctly, but give you a margin of zero. If you can't/don't want to install it, try adjusting the bounding box manually. There is a line near the top of the .eps file which looks like this:
%%BoundingBox: 50 50 554 770
The four numbers are the y offset, x offset, y max and x max of the output (in terms of margins you can think of them as top, left, bottom, right). You can try decreasing the second number (increasing the left margin) to see if that reveals your y axis label.
I would avoid the conversion all together by using one of gnuplot's pdf terminals (I like pdfcairo) and just use ylabel instead of set label 1 ... at graph.... Here's a simple script that you can modify for your purposes:
set term pdfcairo enhanced font "Helvetica,20"
set output "test.pdf"
set ylabel "~x{0.7.}" rotate by 0 #default rotation is 90
set xlabel "x"
plot sin(x)
Ultimately, what is happening with your script is that gnuplot is putting the label off of the viewable canvas. Some reason adobe still puts the label on the (converted) output, but I would assert that they are wrong in this case -- (they're essentially ignoring your bounding box). Of course, you could move/adjust the bounding box as suggested in the answer by andyras -- but I would argue that is a pretty hacky solution.
