leech VS PyQtGraph

WebtoEpub Firefox addon, Leech, WebNovelConverter

I use a command-line tool called leech, which comes with some pre-built configurations for various sites and stories - including Worm. There are other story converter tools out there, and since FanFiction.net's recent API screwup changes I've used WebToEpub for that.

What problem are you running into getting Leech to work? I looked it up, and it seems like you mean this. I tested out locally, and it worked for me out of the box. Pip successfully installed poetry, and poetry installed all of the required components when called from inside leech-master. I did have to download with Royal Road instead of the original Fictionpress, possibly due to cloudflare blocking me for scraping too fast.

It's all at a very approachable level, too. I had to write an epub-maker as a necessary component for a project, and it turned out to be ~150 lines of python. You have to make a few indexes in XML and stick them into a zip file, basically.

PyQtGraph - Interactive and realtime 2D/3D/Image plotting and science/engineering widgets.

Image, 3D, or data visualization applications using OpenCV and the SciPy ecosystem. The Graphics View Framework can display an image and let the user interact with it, and the Python ecosystem is very rich for image processing, data analysis, and visualization. For example, LabelMe for image labeling, PyQtGraph for scientific graphics, or custom QWidget integration in Maya.

I don't think that's related to your error though - from the backtrace, it looks like the plotWidget has plotItem attribute that's somehow been assiged to itself (or maybe some other PlotWidget) , so is just endlessly recursing as it tries to proxy the same attribute lookup (presumably 'clear') to itself. Looking at the source, the plotitem is either created as a new PlotItem() object if not provided, or passed in to the constructor, so I'd check how this gets initialised - eg. does this get set as a property in your .ui file? Are you setting it to the widget itself somehow?

I did something like this recently but I used pyqtgraph: https://www.pyqtgraph.org/

Ah, I agree, Matplotlib is for publication, so slow and pretty. For fast, I use pyqtgraph, which can do that 10 million point plot interaction. And since it's QT, it integrates seamlessly into QT applications.
