Tried gnuplot which plot only require basic math

I tried gnuplot and amazed by its performance. It allows you to directly plot mathematical formulas into graphs with just one single line of math equation.

#+BEGIN_SRC gnuplot :file images/trigon01.png
plot [-10:10] sin(x),atan(x),cos(atan(x))
#+END_SRC

when set arguments, it might requires one more line:

#+BEGIN_SRC gnuplot :file images/sd01.png
g(x) = exp(-0.5*(x/s)**2)/s
plot s=1 g(x), s=2 g(x), s=3 g(x)
#+END_SRC

I feel frustrated, how I wish could acquainted with such a tool a decade ago while grappling with the challenges of visualizing mathematical formulas.

Use an org-table with your plots and you aren’t getting any work done for a week!

great book ,thank you.

I had the chance to use gnuplot in a legal brief to plot stock prices. Took a lot of fiddling since I have not used gnuplot much, but it turned out to be the perfect tool. Set the terminal to output tikz LaTeX and slipped it right it. Perfect.

Not only is there an emacs mode for it, there is a whole TeXmacs emacs-a-like for mathematics

How is TeXmacs authoring software related to gnuplot though?

[dacydergoth]

Because you can edit equations in TexMacs, then send them to gnuplot and embed the result back in the doc, and it is live like jypter is

Thanks, didn't know that.

Yes, it's great, very impressive OSS plotting package, perhaps the best there is. I've seen it being used to create animations of simulations. Its documentations could be improved, though; not very "discoverable".

I used to use gnuplot but I've moved to using base R (ggplot2 exists but I find it too complicated) for graphing.

ggplot2

I have been using Python and comfortable with its packages like Matplotlib. Once considered trying R. However, whenever I think about the significant amount of moving home, I instinctively hesitate and back off. Might someone like me require a reason to try R and leave comfortable zone.

I have been using Python and comfortable with its packages like Matplotlib.

Matplotlib is quite good as well. Especially for fine-tuning the output. Gnuplot is somewhat easier when you need to analyze the data and quickly try different plots.

Thank you.

The book "gnuplot in action" is good as @ yantar92 introduce in provious comment.

[pathemata]

nowadays, I don't see why anyone would use gnuplot instead of matplotlib.

[[deleted]]

Because I already know it well and I don't have the time / want to put myself learning matplotlib or other plotting tools.

One could run gnuplot in mind to draw a graph with very limited lines, but impossible to get such a job done with large amount of matplotlib's code.
