When I plot with image in gnuplot, the label that I set is not displayed. Everything else is correct. Here is my code:
#! /bin/sh
#
# Plotting the color map of correlation using the default Matlab palette
#

7 "#ee0000",\
8 "#7f0000")
set output 'test.png'
set label 'aaa' at 2,17
plot 'Cuup_nf_a090_r050Dj_average' u 1:2:3 with image
EOF
What is strange is: if I plot the data file using a column which doesn't exist as the third data series, for example:
plot 'Cuup_nf_a090_r050Dj_average' u 1:2:4 with image
(I have only 3 columns in the file 'Cuup_nf_a090_r050Dj_average')
Sure, I get only blank (no data) in my image, but the label is displayed correctly.
So it seems that the label is covered by my data palette... I have tried to put 'set label' at the end of code, but it doesn't work either.
Does someone have an idea?
ps: my gnuplot version: Version 4.6 patchlevel 4
Thanks a lot in advance.
Labels have an option front|back to position them on the front or back layer. Default setting is back, so that labels not specifying an explicit layer are hidden when plotting with image:
$data <<EOD
1 2
3 4
EOD
set label 'default, hidden' at graph 0.6, graph 0.7 font ",20"
set label back 'back, hidden' at graph 0.6, graph 0.5 font ",20"
set label front 'front, visible' at graph 0.6, graph 0.3 font ",20"
plot $data matrix with image

I'm doing a gif in gnuplot, and I have my data separated in blocks. I need the points to be white except from just the first row of every data block, which would be an orange point.
Currently my code is:
#...
do for [i=0:int(STATS_blocks-1)]{
plot "positions.txt" index i pt 7 ps 0.5 lc 'white' title "t = ".((i+1)*200)." Myr"
}
As you can see, this plots every data point white, including the first row.
Edited to show variable pointsize also
If I understand your data format correctly:
set linetype 11 lc "orange"
set linetype 12 lc "white"
set style data points
do for [i=0:N] {
plot "positions.txt" index i using 1:2:(column(0)>0 ? 0.5 : 2.0):(column(0)>0 ? 12 : 11) pt 7 ps variable lc variable
}
Variable color (if used) is always taken from the very last using column. Other variable properties work back from there.
I would like to set bold labels in my graph. I use the latex enviroment to set formula at the labels between $ symbols, hovwer the usual \boldsymbol{} doesn't work.
set terminal epslatex standalone color size 4.0in,3.0in background rgb "white" font "Helvetica,10"
set output 'latex.tex'
f(x) = x + 2*sin(x)
set xrange [0:10]
set xlabel '$t$'
set ylabel '$\boldsymbol{q} \cdot n$'
plot f(x)
You should add to your latex file:
\usepackage{amsmath}
You can do this from gnuplot by using the header option of epslatex:
set terminal epslatex standalone color size 4.0in,3.0in background rgb "white" font "Helvetica,10" header '\usepackage{amsmath}'
Hi to whole stackoverflow group,
I am having a series of problems when defining the axes range in my graphic
and format in general, and I would like to share it with you to see if among all we can find the error
I have found on this website a user who has made it similar. My idea is to have something similar like the graphic of the link below. But for some reason, it's probably silly, it does not appear correctly.
My code is as following:
set term post eps enhanced color "Times-Roman" 14
set output "ComparacionPurezaMetodos.eps"
set key off
set style data histogram
set style histogram cluster gap 1
set style fill solid border -1
set boxwidth 0.8
set xtic rotate by 90 scale 0
unset ytics
set y2tics rotate by 90
set y2label 'Ti_3SiC_2 content, wt{/Symbol\045}' offset -2.5
#set xlabel ' '
set size 0.6, 1
set label 'Powder mixture' at graph 0.5, -0.1 centre rotate by 180
plot 'datos.txt' using 1:(-1):3 with labels rotate right, 'datos.txt' using 1:2 with boxes
and the data are very simple:
# index, purity, name
1 98 Ti/Si/TiC
2 94 Ti/TiSi_2/TiC
3 93.6 Ti/Si/C
4 92 Ti/SiC/TiC
5 93 Ti/SiC/C
6 98 Ti/Si/C + Al
and I expect an output image like figure 4 (pag 6) of chapter 1 of this link:
https://books.google.es/books?id=zNWeBQAAQBAJ&printsec=frontcover&hl=es#v=onepage&q&f=false
But my output file does not have to do with this image.
Any idea / help?
Thanks in advance.
For your data, you don't need a histogram. Horizontal bars are sufficient. Instead of rotating a graph with plotting style with boxes you can use the plotting style with boxxyerror.
Make sure that your data separator is TAB or put your labels into "...".
### horizontal bars

set datafile separator "\t"

Result:
My x and y labels are cut off the pic
I found the crop/nocrop option but didn't work.
How can I set a margin? and as you can see the titles (top right) are covered by the data. How can I set a margin there?
The following code comes from my bash script.
#set output
set terminal png large size 1920,1080 enhance background rgb '$BKGD_COLOR'
set output '$PLOT_OUTPUT_DIR/BW_${ArrayFile[$j]}_$DATE.png'
#set data
set datafile separator ","
set timefmt '%d/%m/%Y %H:%M:%S'
set xdata time
set format x "%d/%m/%Y\n%H:%M:%S"
#set axis (new style named 11, disable top and right axis, disable tics on top and right)
set style line 11 linecolor rgb '$TEXT_COLOR' linetype 1
set border 3 back linestyle 11
set tics nomirror font "/usr/share/fonts/dejavu/DejaVuSans-Bold.ttf,16" textcolor rgb "$TEXT_COLOR"
#set grid
set style line 12 linecolor rgb '$TEXT_COLOR' linetype 0 linewidth 1
set grid back ls 12
#set line style
set style line 1 lc rgb '$RCVD_COLOR' pt 1 ps 1 lt 1 lw 2
set style line 2 lc rgb '$SENT_COLOR' pt 6 ps 1 lt 1 lw 2
#set text
set key font "/usr/share/fonts/dejavu/DejaVuSans-Bold.ttf,10" textcolor rgb "$TEXT_COLOR"
set title 'Bandwidth (Mbps)' font "/usr/share/fonts/dejavu/DejaVuSans-Bold.ttf,14" textcolor rgb '$TEXT_COLOR'
#Removed - set ylabel 'Mbps' textcolor rgb '$TEXT_COLOR'
set yrange [0:*]
#plot using the column 1 and 3 of the CSV file. with line points and title 'Bytes Received' and line style 1 (as defined above)
plot '$DIR/ResultsCSV/mg_bandwidth/${ArrayFile[$j]}.csv' u 1:3 w lp ls 1 t 'Bytes Received', '$DIR/ResultsCSV/mg_bandwidth/${ArrayFile[$j]}.csv' u 1:4 w lp ls 2 t 'Bytes Sent'
Set the font-size of your tics when setting the terminal. This size is used to determine the automatic margins:
set terminal png ... font ',16'
Alternatively you can set explicit margins with
set lmargin screen 0.05
set bmargin ...
For possible coordinate types, see e.g. https://stackoverflow.com/a/23180595/2604213
BTW: Use the pngcairo terminal which has a much better rendering quality.
#Christoph provided the answer about the margin, but you asked about your key as well.
In order to fix that, you can put the key in a different position. Doing
set key inside top left
will move the key to the left side, where the data won't cover it up. You can also move it ouside the plot altogether with
set key outside top right
which will move it to the right side and outside of the plot where it won't be covered up.
See help set key for more detail.
I am using gnuplot in version 5.0 in order to plot graphs from Log files which are received from another script. Initially, a script runs which creates the Log files, and inside the same script (upon finishing) a new script which will plot the graphs is executed by receiving some command line arguments.
One of the command line argument for the plotting graph script ($4 specifically) is the path where the data (which will be used by plot command) is located. Upon finishing of execution:
line 0: warning: Cannot find or open file "/comperative_data.txt"
where the command line argument is not used at all. See the source code of the script below:
