Graphing in Textual?

[misterek]

Is there any pattern so far for graphing things in textual? I've been playing around with another library to create graphs, but I suspect that there are terminal codes that aren't completely compatible. For instance:

class TesterApp(App):

    CSS_PATH = "tester.css"

    BINDINGS = [("q", "quit", "Quit")]

    def compose(self) -> ComposeResult:

        yield Header()

        y = plt.sin() # sinusoidal test signal
        plt.scatter(y)
        plt.title("Scatter Plot") # to apply a title
        plt.plot_size(100,100)

        s = Static(Text(plt.build()))
        yield s

        yield Footer()

    def action_quit(self) -> None:
        self.app.exit("quit")

if __name__ == "__main__":
    app = TesterApp()
    app.run()

Screen > Static {
    background: green;
    color: white;
}

Using https://github.com/piccolomo/plotext.

This leads to a... strange looking graph. Interestingly, if I add width: 500 to the css, it displays the graph correctly, with a few straggling lines off to the side. (Wrapping it in a Rich Text was an attempt to get it to work, but has the same result)

Has anyone had any luck with this or a similar library for graphing?

With no width:

With width: 500

I've played around with the different options as well as I think I can, but can't quite get it to display like I hope it would.

Maybe there are other libraries that might work better?

It looks like adding a Textual wrapper for Plottext is planned - see #3029

🤦 Apparently my searching abilities are terrible. Thank you for the pointer. Closing this as 'I'm an idiot'.
