Can we plot both points with smooth csplines in one legend? If we plot them separately two legends generates with separate point and line.
I expect both point and smooth line in one legend as in case of linepoints
If you have a current gnuplot (version 5.4), use keyentry to generate a custom entry for the plot legend.
plot FOO with points lt 2 notitle, \
FOO smooth csplines with lines lt 2 notitle, \
keyentry with linespoints lt 2 title "points + lines"

so, I need to make y axis be exponential and also my observation should be exponential too. Here is code
set yrange[2.8:4.2]
# forecasts with 95 pc conf. interval
plot \
'-' using 1:2 title "log_m" w lines lw 0.5, \
'-' using 1:2 title "forecast" w lines, \
'-' using 1:2:3 title "95-interval" w errorbars

UPDATE
So apparently, the order of options does matter. Wasn't aware of that. Still,
rowi=1
rowf=7
colour=0
plot for [i=0:rowf-rowi+3] filename.'.csv' u ($0+i):2:3:(colour=colour+1):xtic(1) every ::i+1::i+1 w errorbars pt 7 lc var notitle
will start re-using colour after the eight entry where I want a different colour for each of the 10 points plotted.
How do I do that?
In gnuplot, the lc (linecolor) and pt (pointtype) parameters belong to the w (with) clause (see help plot with), so putting notitle between pt 7 and lc var doesn't work. If you move the notitle clause to the end of the plot command line, this will fix the error you are getting. Like this:
plot for [i=0:rowf-rowi+3] filename.'.csv' u ($0+i):2:3:xtic(1) every ::i+1::i+1 w errorbars pt 7 lc var notitle
Without lc var, by default the colours will eventually repeat but you can set the palette to anything you like. See: Gnuplot repeats colors in rowstack histograms
I have the following gnu plot:
# automobile_input.txt
#
set term png
set output "automobile.png"
#
# Fields in each record are separated by commas.
#
set datafile separator ","
set title "Price versus Curb weight"
set xlabel "Price in dollars"
set ylabel "Curb weight in pounds"
set grid
plot 'x' using 1:2
quit
x is a file containing numbers such as
1,2
0.5,4
etc.
I would like to make a few changes to this plot.
At the top of the plot there is "x using 1:2" and I would like to remove that.
Finally, the most important thing: I would like to add another file, y, in the same format, which will be also plotted on the same plot, only with a different sign and color (instead of pluses in red), for example, blue triangles. I would rather also the pluses be circles.
Omit the data series title by using notitle in your plot line. Adding another curve would be done like this:
plot 'x' using 1:2 notitle, \
'y' using 1:2 notitle
The data series points will adjust automagically. To manually specify the format, you might plot with something like this:
plot 'x' using 1:2 with points pointtype 6 linecolor rgb 'red' title "Data X", \
'y' using 1:2 with points pointtype 8 linecolor rgb 'blue' title "Data Y"
You'll usually see scripts online that abbreviate these command to look like:
plot 'x' w p pt 6 lc rgb 'red' title "Data X", \
'y' w p pt 8 lc rgb 'blue' title "Data Y"
I am using Gnuplot to draw step functions from an input file:
plot 'myFile' using 1:2 with steps
I want to fill underneath the plot. something like
plot 'myFile' using 1:2 with filledcurves
But Gnuplot fill underneath the diagram by drawing a line between consecutive points.
How can I fill in underneath the step function?
Use the fillsteps plotting style, which is the same as steps, but the area between the curve and y=0 is filled:
set samples 11
set xrange [0:10]
plot '+' with fillsteps fs solid 0.3 noborder lt 1,\
'+' with steps lt 1 lw 4
I am plotting:
p " file1" u ($2-0.25):8:(.2) every ::1::568, "file2" u ($2):8:(.2) every ::568::1136, "file3" u ($2+0.25):8:(.2) every ::1137::1705
It produces three different keys and three different colour lines. However, I would also like to have the three of them using the same colour and the same legend (key). Is that possible?
You can specify title and linecolor (or fill) for each datafile. To remove the legend entry, use notitle.
plot sin(x), cos(x) linecolor 1 notitle
