dr 🛠️🛰️📡🎧:blobfoxcomputer:So. I want to <a href="https://hachyderm.io/tags/pyqtgraph" class="mention hashtag" rel="nofollow noopener" target="_blank">#pyqtgraph</a> plot some colored items with medium alphas and then overlap them to produce the usual kindergarten color wheel results.But it turns out that <a href="https://hachyderm.io/tags/pyqt" class="mention hashtag" rel="nofollow noopener" target="_blank">#pyqt</a> only supports compositing in the RGB <a href="https://hachyderm.io/tags/color" class="mention hashtag" rel="nofollow noopener" target="_blank">#color</a> space.In fact, the Wikipedia article makes it sound like alpha blending is only even *defined* for RGB. Which I guess makes sense for speed reasons, but I'd still expect some way to put in a callback or whatever for a custom mode.I guess what I'll do it do all the HSV and compositing work in a <a href="https://hachyderm.io/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a> <a href="https://hachyderm.io/tags/numpy" class="mention hashtag" rel="nofollow noopener" target="_blank">#numpy</a> array and the convert to an RGB image and display it that way...?Unless there's a better idea?

Two default axes, two custom axes using "my" <a href="https://hachyderm.io/tags/algorithm" class="mention hashtag" rel="nofollow noopener" target="_blank">#algorithm</a> for tick generation, one for "numbers" and one for "angles".Very, very reasonable behavior! (bottom row is custom ticks) (I know radians are still technically angles, but that's not the point)(I just realized I should have called that feature "degrees" not "angles")One potential upgrade is to compute something for minor ticks. How do I....oh, those are probably the next lower mantissa! Except for snow removal I have nothing else to do today, so....

Ogi<a href="https://ciberlandia.pt/@villares" class="u-url mention" rel="nofollow noopener" target="_blank">@villares</a> if you’re wanting live plot updates that’s sort of <a href="https://hachyderm.io/tags/PyQtGraph" class="mention hashtag" rel="nofollow noopener" target="_blank">#PyQtGraph</a> ‘s thing. I will freely admit that pyqtgraph does not have the plotting customization that matplotlib does but it’s very straight forward to integrate into a Qt application.
