Hello all. I have not found the way to solve the following problem: I want to plot a set of data in only one plot. The problem is that some points of the data should be better plotted in a linear scale (lets say 0 to 100,000) but there are other data points that, exceding the value 100,000, would be better plotted in a logarithmic scale, as they goes in the range 100,000 to 500,000,000. Let's say the data is: X Y 0 100 10000 80 20000 75 30000 60 40000 55 50000 50 60000 48 70000 45 80000 43 90000 41 100000 40 500000 35 1000000 30 5000000 25 10000000 20 50000000 15 100000000 10 500000000 8 (in fact there are much more data points in the 0100,000 interval) Is there a way to plot all these points in the same plot in only one Xaxis showing two different ranges in that axis: linear: 0100,000 logarithmic: 100,000  1,000,000,000 ? The axis would be read, for example, as:  0 2E4 4E4 6E4 8E4 1E5 1E6 1E7 1E8 1E9 Thanks.

One approach might be to 'set log x2' log and plot the data once on x and once on x2 using the ternary operator eliminate the unwanted points. See 'help operators ternary' and 'help set logscale' for details. jab On Tue, Apr 26, 2011 at 12:07 PM, Tomás Navarro <llaurollauro@...> wrote: > > Hello all. > > I have not found the way to solve the following problem: > > I want to plot a set of data in only one plot. > > The problem is that some points of the data should be better plotted in a > linear scale (lets say 0 to 100,000) but there are other data points that, > exceding the value 100,000, would be better plotted in a logarithmic scale, > as they goes in the range 100,000 to 500,000,000. > > Let's say the data is: > > X Y > 0 100 > 10000 80 > 20000 75 > 30000 60 > 40000 55 > 50000 50 > 60000 48 > 70000 45 > 80000 43 > 90000 41 > 100000 40 > 500000 35 > 1000000 30 > 5000000 25 > 10000000 20 > 50000000 15 > 100000000 10 > 500000000 8 > > (in fact there are much more data points in the 0100,000 interval) > > Is there a way to plot all these points in the same plot in only one Xaxis > showing two different ranges in that axis: > linear: 0100,000 > logarithmic: 100,000  1,000,000,000 ? > > The axis would be read, for example, as: > >  > 0 2E4 4E4 6E4 8E4 1E5 1E6 1E7 1E8 1E9 > Thanks.

Thank you very much for the hint, jab, and also for that link I visited time ago and was not able to find this time.

a list of methods you may use: 1. modify the xvalues for x>100000 and set the xtics by hand 2. use x and x2axis 3. plot twice in multiplot mode reset set xtics ("0" 0, "2E4" 2e4, "4E4" 4e4, "6E4" 6e4, "8E4" 8e4, "1E5" 1e5, "1E6" 12e4, "1E7" 14e4, "1E8" 16e4, "1E9" 18e4) plot 'datafilename' using ($1<100000?$1:log10($1)*20000):2 with linespoints pause 1 reset set xrange [0:180000] set x2range [1e0:1e9] set xtics nomirror set log x2 set xtics 0,20000,100000 set x2tics 1e5,10 plot 'datafilename' using ($1<=100000?$1:0/0):2 with linespoints, \ '' using ($1>=100000?$1:0/0):2 ax x2y1 with linespoints pause 1 reset set yrange [0:100] set multiplot set xrange [0:180000] set xtics 0,20000,100000 plot 'datafilename' using ($1<=100000?$1:0/0):2 with linespoints set xrange [1e0:1e9] set log x set xtics 1e5,10 plot 'datafilename' using ($1>=100000?$1:0/0):2 with linespoints unset multiplot Tomás Navarro wrote: > > > Hello all. > > I have not found the way to solve the following problem: > > I want to plot a set of data in only one plot. > > The problem is that some points of the data should be better plotted in a > linear scale (lets say 0 to 100,000) but there are other data points that, > exceding the value 100,000, would be better plotted in a logarithmic > scale, > as they goes in the range 100,000 to 500,000,000. > > Let's say the data is: > > X Y > 0 100 > 10000 80 > 20000 75 > 30000 60 > 40000 55 > 50000 50 > 60000 48 > 70000 45 > 80000 43 > 90000 41 > 100000 40 > 500000 35 > 1000000 30 > 5000000 25 > 10000000 20 > 50000000 15 > 100000000 10 > 500000000 8 > > (in fact there are much more data points in the 0100,000 interval) > > Is there a way to plot all these points in the same plot in only one > Xaxis > showing two different ranges in that axis: > linear: 0100,000 > logarithmic: 100,000  1,000,000,000 ? > > The axis would be read, for example, as: > >  > 0 2E4 4E4 6E4 8E4 1E5 1E6 1E7 1E8 1E9 > Thanks. > >  > WhatsUp Gold  Download Free Network Management Software > The most intuitive, comprehensive, and costeffective network > management toolset available today.

Thank you very much for all three possibilities. Any of them solve the problem. I was trying myself the multiplot plan, but did not find the correct combination. Seems so easy reading them now! :) Tomás. > Date: Wed, 27 Apr 2011 08:45:30 0700 > From: t.sefzick@... > To: gnuplotinfo@... > Subject: Re: [Gnuplotinfo] How to combine a linear range and logscale range in the same Xaxis? > > > a list of methods you may use: > 1. modify the xvalues for x>100000 and set the xtics by hand > 2. use x and x2axis > 3. plot twice in multiplot mode > > reset > set xtics ("0" 0, "2E4" 2e4, "4E4" 4e4, "6E4" 6e4, "8E4" 8e4, "1E5" 1e5, > "1E6" 12e4, "1E7" 14e4, "1E8" 16e4, "1E9" 18e4) > plot 'datafilename' using ($1<100000?$1:log10($1)*20000):2 with linespoints > > pause 1 > > reset > set xrange [0:180000] > set x2range [1e0:1e9] > set xtics nomirror > set log x2 > set xtics 0,20000,100000 > set x2tics 1e5,10 > plot 'datafilename' using ($1<=100000?$1:0/0):2 with linespoints, \ > '' using ($1>=100000?$1:0/0):2 ax x2y1 with linespoints > > pause 1 > > reset > set yrange [0:100] > set multiplot > set xrange [0:180000] > set xtics 0,20000,100000 > plot 'datafilename' using ($1<=100000?$1:0/0):2 with linespoints > set xrange [1e0:1e9] > set log x > set xtics 1e5,10 > plot 'datafilename' using ($1>=100000?$1:0/0):2 with linespoints > unset multiplot > > > Tomás Navarro wrote: > > > > > > Hello all. > > > > I have not found the way to solve the following problem: > > > > I want to plot a set of data in only one plot. > > > > The problem is that some points of the data should be better plotted in a > > linear scale (lets say 0 to 100,000) but there are other data points that, > > exceding the value 100,000, would be better plotted in a logarithmic > > scale, > > as they goes in the range 100,000 to 500,000,000. > > > > Let's say the data is: > > > > X Y > > 0 100 > > 10000 80 > > 20000 75 > > 30000 60 > > 40000 55 > > 50000 50 > > 60000 48 > > 70000 45 > > 80000 43 > > 90000 41 > > 100000 40 > > 500000 35 > > 1000000 30 > > 5000000 25 > > 10000000 20 > > 50000000 15 > > 100000000 10 > > 500000000 8 > > > > (in fact there are much more data points in the 0100,000 interval) > > > > Is there a way to plot all these points in the same plot in only one > > Xaxis > > showing two different ranges in that axis: > > linear: 0100,000 > > logarithmic: 100,000  1,000,000,000 ? > > > > The axis would be read, for example, as: > > > >  > > 0 2E4 4E4 6E4 8E4 1E5 1E6 1E7 1E8 1E9 > > Thanks. > > > >  > > WhatsUp Gold  Download Free Network Management Software > > The most intuitive, comprehensive, and costeffective network > > management toolset available today.
