Used Wplot for Windows?
Developer’s Description
Create plots with millions of data points in seconds. Crazy fast.
Once the data is plotted you can easily use the many tools to explore your plot in great detail by zooming in/out, scrolling your plot and much more.
Mutiple objects (data files/sets) can be plotted and overlaid.
Objects can be individually hidden/viewed as the plot is studied.
wplot does NOT generate data. wplot reads data points from file(s) and generates varied plots based on that data.
A single Windows executable. Simple installation. Just download executable file and run.wplot is 100% FREE to use. No restrictions of any kind. Donations welcome.
