have measurement data and like to plot them as points combined by lines, you will probably do that with the linespoints plotting style. But for some applications it is required gnuplot error bars histogram to combine the data points by non-continuous lines to emphasize that the gnuplot linespoints error bars data came from measurements as shown in Fig. 1.

between its points (code to produce this figure) In Gnuplot exists no line style that can do this directly. But with a little trick it is very easy to achieve. Since https://groups.google.com/d/topic/comp.graphics.apps.gnuplot/H0qsJEWjsDk Gnuplot 4.4. there exists the property pointinterval (see the documentation) in combination with the plotting style linespoints. This property plots not every single point, but only every second for a value of 2 and so on. But if we use the value -1 it tells Gnuplot to insert a little gap between the points and the line. The size of the gap can be http://www.gnuplotting.org/tag/linespoints/ set by the pointintervalbox property. set style line 1 lc rgb '#0060ad' lt 1 lw 2 pt 7 pi -1 ps 1.5 set pointintervalbox 3 We specify a point interval pi of -1 and a point size of 1.5, in addition we set the the gap to a point size of 3. Now we can plot our data with the linespoints style. plot 'plotting_data1.dat' with linespoints ls 1 Using the same data as in the first plot of the gnuplot basics tutorial Plotting data we will get Fig. 1 as a result. Tags: data, linespoints, non-continuous Plotting data April 27th, 2010 | 39 Comments Plotting data like measurement results is probably the most used method of plotting in gnuplot. It works basically like the plotting of functions. But in this case we need a data file and some commands to manipulate the data. First, we will start with the basic plotting of simple data and thereafter look at the plotting of data with errors. Simple data At first we will have a look at a data file. This can be a text file containing the datapoints as columns. # plotting_dat

How do I force gnuplot to draw those. I already tried "set clip one/two" gnuplot share|improve this question asked Jul 13 '15 at 12:56 MaVo159 85 You gnuplot error bars can't, and it doesn't make sense if you don't know where the data point is which this part of an errorbar belongs to. –Christoph Jul 13 '15 at 14:10 Thanks for the information. If it makes sense or not depends on the situation. I can't show all data points, because the interesting portion of the graph would become to small, but it would make sense to have visible error bars to indicate the existence of measurements outside the plotting range. –MaVo159 Jul 13 '15 at 15:38 add a comment| 3 Answers 3 active oldest votes up vote 0 down vote You could use multiplot to achieve this. Set your plot to have zero margins, so the axes are on the border of the canvas, and switch of all tics and borders for the first plot. Switch on the axes, tics etc. again, and do an empty plot that you set at the correct position using set size and set origin. You'll have to do some math to calculate the exact position. share|improve this answer answered Jul 14 '15 at 10:44 Karl 1,144216 If I understand you correctly that would allow me to plot things which are inside the yrange equivalent to the page height (outside the plot borders). That is no
