I’m trying to sort just the 1st column of the following file (“dat0.txt”):

I would like to have a gnuplot script which may or may not plot a file depending on some condition. Using /dev/null if I don’t have to plot a file works, but gives a “Skipping data file with no valid points” warning that I would like to silence.

I’ve got OHLC data for the S&P 500 that I would like to plot as a so-called Renko plot ( https://en.wikipedia.org/wiki/Renko_chart ) in gnuplot. I have transformed the OHLC data to fixed-size bricks represented in data.dat as the upper and lower diagonal corners of rectangles:

I am trying to draw a few graphs relative to a time axis that should automatically draw anything from the samle starting 2 days back since time of plotting. I couldn’t figure it out with gnuplot’s mechanics, so did this

I have some data files with the following structure. The first three columns are 3D coordinates (x, y, z) of points and the fourth column is an intensity value. The rows of values per group (i.e. points per group) can vary. So I need a function that automatically counts the number of points when plotting so that I can get a legend title like “group_0001: 10 pts.”. I also want the intensity of the points to be plotted with transparency instead of size.

Here is one part of my script:

The Gnuplot-Workflow “Gnuplot-Console + Editor (Geany) using Gnuplot 5.4.x and Linux (Xubuntu 22.04) does’nt work by using Windows 10.

How can i plot an energy level diagram similar to the attached figure for the data file given below?

I need assistance with extracting and analyzing the egeg​ and t2gt2g​ orbitals’ contributions from my VASP DOS calculations. I have performed the necessary calculations and obtained the DOSCAR and PROCAR files, but I’m unsure how to proceed with parsing these files, identifying the specific orbital contributions, and plotting the results for further analysis.

When drawing a triangle using Gnuplot, it does not display. The script is as follows
`set xrange [ 36.00000 : 38.30000 ]
set yrange [ 37.9 : 38.40000 ]
set zrange [ -23635.4 : 1000.00000 ]
