plotting issue

[mburnskaurin]

This runs in normal 3.2 but with WASM it does not

I get this error message.

I was able to get the first plotting step to work by rewriting line 11 as:

gc[i].plot(data=[[0,i], [1,i]])

I would imagine that, with less strict syntax usage, the engine interprets the second argument passed in the plot() method not as a data point to plot but as some other attribute. When substituting the line I have written, I can't get the gr.delete() on line 21 to work. I get the following error, which I can't make sense of:

AttributeError: delete. Did you mean: 'delta'?

Again, I haven't changed anything besides line 11. When double-checking some data types and trying to look at methods available to the objects, I can't find any kind of delete method available to the graph or gcurve here. I searched the documentation for another VPython object using the delete() method and found the Button objects. I tried creating a simple dummy button, and when I went to run the delete() method on it, it gave me an error saying that the method didn't exist. This might be a separate issue to submit, but I am unsure.

Thanks. When I convert to a list but without "data=" I get a more informative message that tells me what is allowed.

Here is documentation on delete for a graph curve:
https://www.glowscript.org/docs/VPythonDocs/graph.html

A previous issue I raised was about the absence of scene.delete(), apparently delete is simply not implemented.

This is helpful. Some of the glowscript functions accept many variations on what can be passed and how it's interpreted. I tried to handle to main cases that I've seen, but I've clearly not seen everything! I don't have a ton of time to work on this right now, but I'll try to work my way through the list over time.
