![]() This latter one was a graph that I very badly wanted, but did not find.īut we can change all this, and this is what I would like to set out to do. Have you ever found pie charts made by gnuplot? Perhaps a 3D pie chart? A 3D exploded pie chart? Or 3D bar graphs? Probably not too many. And second, some plot types cannot be generated at all. First, due to the initial difficulty of setting up a figure properly, most figures generated by gnuplot look the same, and follow the same simple scheme. However, there are obvious problem with this whole concept. So, the tremendous convenience of scriptability should not be underestimated. I mean, all figures with a single key-stroke. At one point, I had to produce literally hundreds of figures per day, and I could do it with one key-stroke. But these can be automated, so to speak, and usually, the lookout of a figure must be set up only once, and those settings can be re-used many times. given, and it takes some time to set all these. It is trivial to plot sin(x), but then the graph must be "dressed" up, proper limits, labels, ticmarks, colour etc. What I mean by this is that many people rejoice in this fact, and they do not make the effort to turn the figure into something appealing. I liked the idea that one needn't see the data file in order to plot it, and that functions can very easily be plotted. lbt01_mean cannot be written in a file using system.īesides, since the data file has samples for 0.1 to 1.7 in steps of 0.1 (column 9), I would like to ask if is there a way to short the Gnuplot script.I have been using gnuplot for some 10 years by now, and during this time, I have become quite fond of it. It looks like the results of stasts, e.g. Gnuplot stats pdf#(2.262 is the value of the t-student pdf for 95% confidence interval and 9 degrees of freedom). System("(0.1 lbt01_mean (lbt01_mean - 2.262*lbt01_ssd/sqrt(lbt_records)) (lbt01_mean + 2.262*lbt01_ssd/sqrt(lbt_records))) > lbt.dat")īut I get error in the last system command to save the values in the lbt.dat file. I have tried to write the values x mean min max in a file with this system("touch lbt.dat") The formula of min and max values uses the STATS_mean, STATS_ssd, and STATS_records of column 13 with equal value in column 9. I want to plot the mean of column 13 (last column) with the confidence interval and use Gnuplot yerrorlines, which need data in four columns x mean min max. It has ten samples with column 9 = 0.1 and the same with value 0.2. I would like to plot means and confidence interval with Gnuplot. ![]()
