I recently setup a cron on one of my servers to monitor the connection status. Basically a ping is issued every minute and the result is appended with the date to a data file. I am currently able to fetch the data file trough apache and to generate a graph with gnuplot locally. But I … Read more
I’ve needed to do some more sophisticated graphing and plotting as of late. While I know that gnuplot is up to the task, and can do it all from the command line, are there other, simpler or more powerful tools that I’m missing? I’m a bit oldschool, so I tend to think of sed, awk, … Read more
I found a very weird way to plot horizontal lines of discrete values with labels on the left or on the right of the lines I construct an input data file where: the values in the 1st column determine the amplitude of the horizontal lines the values in the 2nd column are repeated to draw … Read more
I have a file containing x, y, z data. I want to create a 3D surface but I have no idea how to do it. I have created a file with the data but when I execute it in gnuplot I get the following message ” 2 columns only possible with explicit pm3d style (line … Read more
I am running a program which uses a plotting library for gnuplot. I am running a script and am supposed to view the resultant plot in real time. Inside the do loop, the plotting command would come up say 100 times. Because of this I am obtaining 100 seperate gnuplot windows containing the plot. The … Read more
Gnuplot’s set term dumb is useful for visualizing data directly on a remote PC, where a GUI may not be available. However, I am seeing an issue, where the legend becomes obscured, causing the result to be unreadable. It seems like the plot lines are put on top of the legend: >>> gnuplot -e “set … Read more

set mouse mouseformat seems not to work when specifying format that includes timedate data. set mouseformat 3 gives you timedate vs y-axis, timedate format being previously specified with set timefmt. But if you explicitly provide timedate format to the mouseformat statement, it gets nuts: for example, set mouse mouseformat “%d %4.1f” will not give day … Read more
