Plot "registrations.dat" using 2:xtic(1) title "Total" lt rgb "#406090",\ at -5,-20 plot data/fermistate.res u (log(2)):(log(3)) t fermi-dirac w l lt 1 lc rgb black, u (log(4)):(log(5)) t full degenerate w. In charts with multiple columns of data it would be smart to add the legend that we removed in the previous post. The bars slightly overlap, which we can fix by changing the box width to a slightly smaller value: set boxwidth 0.8 Let’s add a second plot: set style data histograms Now we’re all set to start plotting multiple bars. This looks a lot like the final result from the previous post. This should do what you need: set style line 1 lt 1 lw 3 pt 3 lc rgb 'red' set style line 2 lt 3 lw 3 pt 3 lc rgb 'red' set style line 3 lt 1 lw 3 pt 3 lc rgb 'blue' set style line 4 lt 3 lw 3 pt 3 lc rgb 'blue'. We then set the plotting style to “histograms”. To add color, you can use 'lc rgb 'color''. We change the boxwidth to “1” (from 0.6 in in the previous post). Plot "registrations.dat" using 2:xtic(1) lt rgb "#406090" Let’s first see how that works with a single bar: set boxwidth 1 The plotting method we use can’t deal with that. While that could be a useful way to represent your data, what if you want the bars to appear next to each other? Now we run into a problem. If we add the “with boxes” option to the second plotting rule, we’ll see that it creates overlapping bars: plot "registrations.dat" using 2:xticlabels(1) with boxes lt rgb "#406090",\ This is what it produces:Īs you can see, it plots the third column of data as “X”s on top of the current bar. using Gnuplot U LinRange(-,, 100) V LinRange(-,, 100) r 0.5 x 1 + cos(u) + r cos(u) cos(v) for u in U, v in V y r sin(v) for u in U, v in V z sin(u) + r sin(u) cos(v) for u in U, v in V bgcp1 'set object rectangle from screen 0,0 to screen 1,1' bgcp2 ' behind fillcolor '212946' fillstyle solid noborder. We define the third column and set a different color for the second set of data. To plot a second set of data, we just add another plotting rule after the first one: plot "registrations.dat" using 2:xticlabels(1) with boxes lt rgb "#406090" ,\ In the previous post, we used the “plot … with boxes” method of plotting bar charts. We will re-use the Gnuplot settings from the previous post. Such charts take multiple columns of data and plot them grouped in the chart.
#Gnuplot lt how to
In this post I want to show you how to plot bar charts with multiple bars. Those were simple bar charts with a single bar. In my previous post I showed how to generate good looking charts with Gnuplot.
