increase the spacing between xtic in clustered bar graph (histogram)

gnuplot

Solution

There isn't an explicit option to prevent overlapping of labels.

In your example it is enough to decrease the white spacing to the left and right plot border a bit with

set offset -0.3,-0.3,0,0

which gives you with version 4.6.3:

Other options are e.g.

Increase the canvas size (`set terminal ... size ...`). Note, that `set size` doesn't affect the image size, but only the size of the graph.

For very long labels you can rotate the text e.g. with `set xtic rotate ...`.

Problem

Sorry if this looks like simple question (probably) but I searched around to get some solution with no avail. I have plot a bar graph as shown (attached) here. My problem is to adjust the spacing between label for each xtic which overlap to one another. If you notice the bar graph I attached here, at the x-axis, the "Third label" and "Fourth label long" overlap to each other. Is there anyway to control the spacing so that the labels are not overlap? Additionally, I need the legends (ring1, ring2 and ring12) to be in italics. Since I am using "terminal pngcairo", is there way to do it in italics? ``` set terminal pngcairo size 550,350 enhanced dash set output "xplot_ACF_ring1-ring2-head-plots2.png" set macro labelFONT="font 'arial,22'" scaleFONT="font 'arial,12'" scaleFONT2="font 'helvetica,13'" keyFONT="font 'arial,18'" ######################################################################################## set ylabel "Time in (ns)" @labelFONT set ytic @scaleFONT set xtic scale 0 @scaleFONT set size 1.0, 1.0 ######################################################################################## ring1 = "#ff0000"; ring2 = "#7FFF00"; ring12 = "#0000FF" set auto x set yrange [65:90] set style data histogram set style histogram cluster gap 1.5 set style fill solid 1.0 border -1 set boxwidth 0.9 relative plot 'mal-cel-iso-bcm-ring1-ring2-head-bar-plot2.dat' using 2:xtic(1) ti col fc rgb ring1 ,\ '' u 3 ti col fc rgb ring2 ,\ '' u 4 ti col fc rgb ring12 ``` The data for the above script is ``` Title "ring1" "ring2" "ring12" "First label" 70 76 77 "Second label" 68 71 69 "Third label" 76 72 68 "Fourth label long" 75 76 77 ``` Below is the plot I get after executing the script. The re-edition of this post start here: I would like to add error bar in this plot. The sample data is below: ``` Title "ring1" "ring2" "ring12" "" 77.295326 2.2 74.829245 3.2 78.238016 2.1 "" 77.613533 6.2 74.123269 1.5 79.704782 3.6 "" 76.589653 2.1 71.704465 2.6 78.736618 4.2 "" 75.996256 0.4 73.407460 3.3 77.290057 2.5 ``` The third fifth and seventh columns are actually the error values. I wish may thanks in advance.
