For desktop applications, to display graphics on the screen and support mouse interactions, it is necessary to have a GUI framework. For Python, the built-in GUI framework is Tkinter. However, it is the only GUI framework. Many developers may choose other GUI frameworks such as PyQt, wxPython, etc.. See:
In previous versions of ChartDirector, we do provide real time chart examples for the CGI framework. However, CGI is no longer commonly used nowadays, so we remove CGI examples in ChartDirector 7.
We also have a real time example written in PyQt5. We wrote that for one of our customers.
We believe it is possible to use ChartDirector for real-time charts in most if not all of the Python GUI/web frameworks. However, because there are so many of them, it would not be practical for us to develop sample code and to support all of them.
Would you mind to clarify whether you are interested in desktop and web applications, and which framework you are using?
