(Standalone) Software for plotting graphs of large amounts of data and allowing you to scroll/zoom I've got some temporal data taken from a data logger that I'm trying to plot in a graphical form (as a line graph). Because it's a large amount of data, plotting it one one big graph (e.g. in Excel) makes it difficult to explore the visualised data as you can't really zoom in and scroll through the data. What I'm looking for is some standalone software that can plot the data as a line graph, but also allow the user to easily scroll through the graph along the horizontal (time) axis and be able to zoom that axis in and out. Ideally, the software would be free and be GUI driven. Does anyone know of any such software?
Thanks,
 A: A survey of interactive plotting software with a 10 million point scatter plot benchmark on Ubuntu 18.10
I have published this survey at: https://stackoverflow.com/questions/5854515/large-plot-20-million-samples-gigabytes-of-data/55967461#55967461
Here is a copy of the summary of results:
Does it handle 10 million points:
VisIt       Yes
Paraview    Barely
Mayavi      Yes
gnuplot     Barely on non-interactive mode.
matplotlib  No

Does it have a lot of features:
VisIt       Yes, 2D and 3D, focus on interactive.
Paraview    Same as above.
Mayavi      3D only, good interactive and scripting support, but more limited features.
gnuplot     Lots of features, but limited in interactive mode.
matplotlib  Same as above.

Does the GUI feel good:
VisIt       No
Paraview    Very
Mayavi      OK
gnuplot     OK
matplotlib  OK

A: Gnuplot is free, open source and highly versatile and what I use and I think it will meet your needs. You can point and click with the mouse to zoom in and out on any part of a graph, and you can even write a script to scroll through the data as if watching a film.
A: After much searching, I have found exactly the software I am looking for:
http://www.datplot.com/
Simple, GUI-driven software that allows you to import raw data and plot graphs, with dynamic scroll and zoom.
A: You could also try Plotly - it's a web-based interactive graphing app
A: I have launched a software recently www.winplotter.com, which suits the needs you specified.
