I have three different lines, where colours and their dashes means different things which I want on one plot, instead of three. How do I accomplish that?
set datafile separator comma
$sample <<EOD

set format x '%Y'

plot '$sample' u 1:2 title "UK/Business" with linespoints dt 3 lw 5 pt 7 lc "red"
plot '$sample' u 1:2 title "USA/Social" with linespoints dt 3 lw 1 pt 7 lc "blue"
plot '$sample' u 1:2 title "UK/Social" with linespoints dt 3 lw 5 pt 7 lc "blue"
E.g. blue is "Social" and lw 1 (fine dots) is for USA.
Please check the manual or help plot. Plot elements for the same plot are separated by comma.
Syntax:
plot {<ranges>} <plot-element> {, <plot-element>, <plot-element>}
To improve readability you can split long code lines into several lines by using \. Note that no character is allowed after \ in the same line except carriage return/line feed.
Try this:
plot '$sample' u 1:2 title "UK/Business" w lp dt 3 lw 5 pt 7 lc "red", \
'' u 1:2 title "USA/Social" w lp dt 3 lw 1 pt 7 lc "blue", \
'' u 1:2 title "UK/Social" w lp dt 3 lw 5 pt 7 lc "blue"
Addition: (a filter depending on two (string)-columns)
You can implement a filter by using the ternary operator. Check help ternary and help strcol. A value which does not pass the filter will be set to NaN. If you still want to your points being connected with lines, you need to set datafile missing NaN.

I know how to use filledcurve with using 1:2:3 to fill the area between the curves described by columns 2 and 3.
I also know how to smooth a single curve using acsplines with using 1:2:(0.1) (with 0.1 being the smoothing weight for each point).
But I fail to combine the two, i.e. fill the area between two smoothed curves. All variants I try give me error messages like duplicated or contradicting arguments in datafile options.
This is what I tried:
plot 'datafile' using 1:2:3:(0.1):(0.1) smooth acs with lines
plot 'datafile' using 1:2:(0.1):3:(0.1) smooth acs with lines
Is this combination possible at all? How is the syntax then?
I guess you can't combine smooth acspline and with filledcurves, but I also don't know why this shouldn't be possible.
Well, as a workaround, plot your smooth acspline curve into a data table first and then plot it with filledcurves.
Code:
### filled acspline curve
reset session
$Data <<EOD
1 2
2 4
3 3
4 1

# plot your acspline data into a table
set table $ACSpline
plot $Data u 1:2 smooth acspline
unset table
set style fill transparent solid 0.1
plot $Data u 1:2 w lp pt 7 lc rgb "black" ti "Original data", \
$Data u 1:2 smooth acspline lw 2 lc rgb "red" ti "acspline", \
$ACSpline u 1:2 w filledcurves x1 lc rgb "red" ti "acspline filled"

Addition:
There is another way to get data into a table. Check help set print.
With this, you can get the data of the two splines into one datablock and can plot the area between them. Maybe someone knows a simpler way to achieve this.

I'm trying to use Gnuplot to create a line chart. Each line is represented by a different color. What I want is the key has the same color as the line color. This is what I have right now, current version. Is it possible to set the text 'Line 2' colored as orange, 'Line 3' colored as red, etc?
This is what I wrote in the gp file:
set xlabel'x-axis'; \
set xrange[0:25];\
set ylabel 'y-axis';\
set yrange [2:9];\
set key left top;
p 'test.dat' using 1:2 w linespoints lw 5 lc rgb '#aadc32' pt 17 title 'Line 1' ,\
'test.dat' using 1:9 w linespoints lw 5 lc 'orange' lt 1 title 'Line 2',\
'test.dat' using 1:6 w linespoints lw 5 lc 'red' lt 8 title 'Line 3',\
'test.dat' using 1:7 w linespoints lw 5 lc 'violet' pt 6 title 'Line 4',\'test.dat' using 1:8 w linespoints lw 5 lc rgb '#b5367a' pt 19 title 'Line 5',\
'test.dat' using 1:3 w linespoints lw 5 lc 'cyan' pt 9 title'Line 6',\
'test.dat' using 1:4 w linespoints lw 5 lc 'blue' lt 9 title 'Line 7',\
'test.dat' using 1:10 w linespoints lw 5 lc rgb '#1c1044' lt 5 title 'Line 8',\
Thank you so much.
Unfortunately not. The plot title does not (now, gp5.2pl0) recognise the "textcolor" specifier.
plot x lw 3 lc rgb "blue" title "x" tc rgb "blue" # doesn't work
You can only print an empty (" ") plot title, and overprint it with a coloured label
set label 1 at 8,1 "bluetitle" tc rgb "blue"
That requires some fiddling with the placement of the label, of course.
You might put up a feature request on https://sourceforge.net/p/gnuplot/feature-requests/
How can I make the key "symbols" black in colour when using palettes?
I think you cannot control this directly, here a workaround:
plot 'MOD1.dat' u 2:3:1 w p pt 7 ps 2 lt black, \
'MOD1.dat' u 2:3:1 w p pt 7 ps 2 lt palette notitle
So, we first plot the data without legend in black, then plot the data points but no legend. The nice thing about this approach is that there is no need to fix the x or y range.
I would just create a dummy line and use notitle on the real lines. Something like
set yrange[0:1]
plot "realdata1.data" u 1:2 w linespoints lt 1 notitle , \
"realdata2.data" u 1:2 w linespoints lt 2 notitle , \
1/0 w linespoints lt 1 lc rgb 'black' title 'Model1', \
1/0 w linespoints lt 1 lc rgb 'black' title 'Model2'
Then replace lt 1 with whatever you have used for style in your current plot. Note that you'll need to use set yrange for gnuplot to accept the dummy curve
This is My data :

1_MAC_r 8416.19 8310.21 8246.49
and here is my gnuplot code :
plot "dat" using ($0+1):2 with linespoints pt 8 ps 2 lt 2 lw 4 lc rgb
"green" title "DMSR","dat" using ($0+1):3 with linespoints pt 5 ps 2
lt 3 lw 4 lc rgb "blue" title "Alarm","dat" using ($0+1):4 with
linespoints pt 6 ps 2 lt 4 lw 4 lc rgb "red" title "Emergency"
and here is my out put :
But In the step part I want to have 18_AGT_s and 18_MAC_s and 9_MAC_s and .... for example on the X part I want to have 18_AGT_s in stand of 1 or I want to have 18_MAC_2 instand of 2 and 9_MAC_r instand of 3 etc. Any help thanks
Use the xticlabels() option with the column number with the labels as argument (1, in this case):
# Optionally rotate labels so they fit
set xtics rotate
plot "dat" using ($0+1):2 with linespoints pt 8 ps 2 lt 2 lw 4 lc rgb \
"green" title "DMSR","dat" using ($0+1):3 with linespoints pt 5 ps 2 \
lt 3 lw 4 lc rgb "blue" title "Alarm","dat" using \
($0+1):4:xticlabels(1) with linespoints pt 6 ps 2 lt 4 lw 4 lc rgb \
"red" title "Emergency"
Here you only need to use it for the last plot instance so that it overwrites the number options.
I have the following line styles defined in gnuplot:
set linetype 1 lc rgb "red" lw 3 pt 7
set linetype 3 lc rgb "red" lw 1 pt 7
It appears as though the points derive part of their size from the lineweight. I'm using these styles inside of a plot for loop with linetype cycle using the same style for a cspline and the corresponding points, so I don't see any easy way to just define a separate style for the points.
I get results like this:
The points respond to pointsize but the point in linetype 1 is still slightly larger (presumably from the thicker border).
Is it possible to get the points in these two styles to be the same size?
In response to Miguel's comment, a more complete example of my use case is:
filenames = "A B C D"
set linetype 1 lc rgb "blue" lw 3 pt 7
set linetype 2 lc rgb "red" lw 3 pt 7
set linetype 3 lc rgb "blue" lw 1 pt 7
set linetype 4 lc rgb "red" lw 1 pt 7
set linetype cycle 4
plot for [file in filenames] file.".csv" \
using 1:2
title file \
smooth csplines, \
for [file in filenames] file.".csv" \
u 1:2 with points notitle
linetypes 5-8 get set by the cycling and are used by the last part of the plotting command. Recommendations on another way to do this would be welcome!
For your very specific case you can set more styles, and do it rather automatically with a do for loop (reusing your code):
filenames = "A B C D"
do for [i=0:1] {
set linetype (4*i+1) lc rgb "blue" lw (i == 1 ? 0 : 3) pt 7
set linetype (4*i+2) lc rgb "red" lw (i == 1 ? 0 : 3) pt 7
set linetype (4*i+3) lc rgb "blue" lw (i == 1 ? 0 : 1) pt 7
set linetype (4*i+4) lc rgb "red" lw (i == 1 ? 0 : 1) pt 7
}
set linetype cycle 8
plot for [file in filenames] file.".csv" \
using 1:2 \
title file \
smooth csplines, \
for [file in filenames] file.".csv" \
u 1:2 with points notitle
With some simple data files:
For some terminals the size of filled point types depends on the linewidth because they have a border. This is the case for all cairo-based terminals (pdfcairo, pngcairo, wxt and cairolatex), whereas other terminal like svg, postscript, qt don't show this behaviour.
As test case consider
set linetype 1 lc rgb "red" lw 3 pt 7
set linetype 3 lc rgb "red" lw 1 pt 7
set samples 11
set style function linespoints
plot x lt 1, x + 0.5 lt 3
Considering that you want to have the linepoints samples in the legend, you're best choice is to reduce the point size a bit for the line type with the larger linewidth, like
set linetype 1 lc rgb "red" lw 3 pt 7 ps 0.9
The choice of the scaling factor must be determined manually.
