Need to create a diagram for a biquad filter in c++


Hi again! I’m developing this FIlterDelay vst / AU and I need to create a diagram to show to the user what kind of filter he’s using.
An example here:

Is there a JUCE way of doing that or I need to use an external c++ library?
If I need an external library, can someone give me an advice?


Ok, I’ve found a way to do the graph.
It is a class from sender by called JUCE Filter Graph Component.

But if I insert the classes in my project, I receive these errors

I also had to correct the eqType:


What are the previous errors?
