When using steps/fsteps, is it possible to fill the area under the line? I am plotting a histogram of resource consumption, and fsteps work well. It means the area under the line matches the resource consumption over time. Using un-filled fsteps means it is difficult to compare two resources on the same axes, as frequently one line 'disappears' behind the other. Unfortunately, filledcurves is not a good aproximation due to the low number of samples. The presence of other filled plots makes this feel like I am missing something. Is there a way to achieve filled steps/fsteps (or has anyone planned to implement this?) Many thanks -- Mark |

But if you fill them, you run a significant chance of making them _impossible_ to compare, because a filled bar will completely vanish behind a higher one. |

In my case the graph I would like to be filled is always below, or equal to, the other graph. eg. I want to compare total I/O (line) with cached I/O (filled). The result of using a filled graph and a line makes the graph very clear to interpret. Nevertheless, is it not always the case that the ordering can be used to draw the line over the filled area?

With boxes, I am limited to having the points at the centre of the box (unlike with fsteps, where it is to the right). Or is there another way?

generate the internal data, which is used when plotting with 'fstep', by hand
and
write the datapoints into temporary files, which are then used for the final
plot command.
assuming, that you have one datafile with three columns (x,y1,y2):
set term push
set term dumb
plot 'datafilename' using 1:($0>0?PLOT=PLOT.sprintf("%f %f\n%f
%f\n",xlast,$2,$1,$2):PLOT=sprintf("%f %f\n",$1,$2), xlast=$1, $2)
set print 'tempfile1.dat'
print PLOT
unset print
plot 'datafilename' using 1:($0>0?PLOT=PLOT.sprintf("%f %f\n%f
%f\n",xlast,$3,$1,$3):PLOT=sprintf("%f %f\n",$1,$3), xlast=$1, $3)
set print 'tempfile2.dat'
print PLOT
unset print
set term pop
plot 'tempfile1.dat' using 1:2 with filledcurves x1, 'tempfile2.dat' using
1:2 with filledcurves x1
for 'steps' use
...
plot 'datafilename' using 1:($0>0?PLOT=PLOT.sprintf("%f %f\n%f
%f\n",$1,ylast,$1,$2):PLOT=sprintf("%f %f\n",$1,$2), ylast=$2, $2)
...
plot 'datafilename' using 1:($0>0?PLOT=PLOT.sprintf("%f %f\n%f
%f\n",$1,ylast,$1,$3):PLOT=sprintf("%f %f\n",$1,$3), ylast=$3, $3)
...
instead.

Thanks for the tip. I'll try this when I get a moment.
Whilst pre-processing the input data could be made to work, in the long
term it would be beneficial if gnuplot were able to do this. Is anyone
working on implementing filled steps/fsteps within gnuplot? I would very
much like to see this feature.
Alternatively, does anyone have any advice if someone were to begin to
look at the source code with a view to implementing it?
