Dear Forum,

I've been happily using Qwt in C++ for some time. Though, the quality of the graphics (plot lines etc.) in Qwt doesn't visually satisfy me as much as say Matlab or Matplotlib (Python) does. If you take a look at this video, where Matplotlib and PyQwt are showcased side by side, you'll notice that the graphics quality of the lines in Matplotlib is somewhat better than Qwt's. I've played around with anti-aliasing, line thicknesses, cap styles and such, but I've been unable to get a look closer to what Matplotlib or Matlab can offer out of the box. What I want to achieve is smooth, quality-looking lines in Qwt.

I'd appreciate any input on the subject.

Best regards.
