Gnuplot grid8/5/2023 # Placement of the a,b,c,d labels in the graphs POS = "at graph 0.92,0.9 font ',8'" As you can see in the code block above, the set label command contains the same position for every graph. 2 A straightforward use of the multiplot command to plot four different functions ( code to produce this figure)īut before we fix this we will introduce the use of macros in order to shorten the code a lot. The xtics and the ytics are just the same in every graph and are not needed to be displayed on every graph.įig. As you can see this is not an ideal case to use the space in the figure. Using this simple approach we will get Fig. If we don’t do that, then on the last graph all four labels will be present. Note that we overwrite the label 1 for every graph. We also added a label to every graph in order to identify them easily in the figure. # - GRAPH a set label 1 'a' at graph 0.92, 0.9 font ',8' plot f( x) with lines ls 1 # - GRAPH b set label 1 'b' at graph 0.92, 0.9 font ',8' plot g( x) with lines ls 1 # - GRAPH c set label 1 'c' at graph 0.92, 0.9 font ',8' plot h( x) with lines ls 1 # - GRAPH d set label 1 'd' at graph 0.92, 0.9 font ',8' plot k( x) with lines ls 1 unset multiplot In a first attempt we just use the multiplot command: # Start multiplot (2x2 layout) set multiplot layout 2, 2 rowsfirst The functions are given by: # Functions (1/0 means not defined) a = 0.9 f( x) = abs( x) < 2 * pi ? a * sin( x) : 1 / 0 g( x) = abs( x) < 2 * pi ? a * sin( x pi / 2) : 1 / 0 h( x) = abs( x) < 2 * pi ? a * sin( x pi) : 1 / 0 k( x) = abs( x) < 2 * pi ? a * sin( x 3.0 / 2 * pi) : 1 / 0įor an explanation of the used syntax to declare the functions have a look at the Defining piecewise functions article. 1 A multiplot with reduced axes labeling and nicely arranged graphs ( code to produce this figure) Tags: data, filledcurves, for, index, labels, multiplot, stats, stringįig. 2 – you should adjust the xrange and yrange values accordingly. If you want to plot a subset of states – as in Fig. The plotting of the state names is easily achieved by the labels plotting style:Īt the end we provide the list with the index numbers and the corresponding states. ( code to produce this figure, USA data, election data) 2 Names and election results of single U.S. This allows us to put them in the map as well, as you can see in Fig. The data file with the election results includes also the names of the single states and a coordinates to place them. Plot for 'usa.txt' i idx u 2:1 w filledcurves ls ELEC,\Īlaska and Hawaii are then added with additional plot commands and the help of multiplot. ELEC will return the election result for the state with the index 0. In a second step we plot the state borders and color the states with the help of the ELECstring. Stats 'election.txt' u 1:(ELEC = ELEC.sprintf('%i',$2)) During the parsing of every line the election result stored in the second column will be added at the end of the ELEC variable. The stats command is suitable for this, because it parses all the data but doesn’t try to plot any of them. 2.įor drawing a single state in red or blue we first collect the results for every single state in the string variable ELEC. With the help of these two data sets we are able to create Fig. The election result can be 1 or 2 – corresponding to blue and red. In addition to the state border data we have another file that includes results from an example election and strings with the names of the states. At the end of this post the corresponding index numbers for every state are listed. This allows us to plot a single state with the help of the index command. Two double lines divide the single states.
