gnuplot y1 y2 common zero

Is there an easy way to make gnuplot automatically show y1=0 and y2=0 at the same height in the image while the y1 and y2 axes have different scales? The only way I am aware is to make sure the proportional distance from zero on the high and low bounds are the same for y1 and y2 For example set yrange [-1:2] and set y2range [-10:20] would work because -1 is to -10 as 2 is to 20. Here's an example #!/usr/bin/gnuplot -p set term wxt #not important unset key set autoscale set xrange [0:1] set xzeroaxis #shows a dotted line where y=0 for y1. set yrange[-1:2] #set y2range[-10:20] #if you set an explicit range, it obviously won't work unless you plan it perfectly (like this) #set y2range[-10:] #this does the minimum to get the plot in the frame (here -10 is the minimum, but the maximum seems to not really matter #set y2range[:20] #set y2range[:] #this is equivalent to just not having a set y2range line. set xtics 0.2 set ytics 0.3 set y2tics 1 set mxtics 5 set mytics 5 set my2tics 5 set ytics nomirror #makes y1tics only show up on the left f(x)=1 g(x)=10 plot f(x) axis x1y1 lc rgb 'blue', \ g(x) axis x1y2 lc rgb 'red';
