Build of MathGL with best performance

[Sean Saud]

Professor Alexey,

What components of MathGL should I use to have the best performance? I will be processing huge amounts of data and plotting the data in real time. By the way, I am now using Centos 7 x86_64.

Sincerely,

Sean

Dear Sean,

If you have a huge amount of data then you probably need to use direct export to a bitmap file (like PNG, JPEG and so on), because GUI redrawing may be slow. But you need to test this on your computer, since MathGL draws plots rather quickly.

Also don't forget to call SetQuality(6) first to reduce memory usage, but this will disable vector output (like EPS, SVG and so on). Alternatively, you can use the combination of functions Rasterize() and Clf() to draw part of the plot as a bitmap one, and part of the plot (like axis, text, annotations, etc) as a vector one. Or you can first call SetQuality(6) for bitmap output, and switch to SetQuality(2) for vector one later.

Thank you so much for the fast answer! But my end goal is to be able to plot live data (data is being collected), so I wanted it to display it on a GUI. What widget would you recommend using? FLTK, glut, or qt5?

Sincerely,

In my opinion, FLTK is faster overall. However, the difference between Qt5 and FLTK widgets is not significant since both use MathGL core for drawing plots.
