A library for visualizing time series, drawing graphs?

Question

infographics

Hello!
Please tell me a library that can beautifully draw data, in my case it is two-dimensional data, the view is a graph. It is planned to be used in a commercial product, so if you know one that allows this possibility for free, I will be very happy if you share it. The preferred language of the library is c++. Thank you!

Answer 1

I used Qt + Qwt for such purposes . If you are not afraid to open your source code, then you can use it. I also found the MathGL
library , it seems to work even without additional libraries.

Answer 2

I would recommend GLE despite using my own scripting language.

Answer 3

a GLE only as a standalone application? can't you use the library?
