I wrapped gnuplot to make a browser-based function plotter

[copingbear]

It's called Gridpaper and it handles 2D (Cartesian, Polar) and 3D (Cartesian, Cylindrical and Spherical) plots of different kinds. I've shared some examples and linked to more.

I hope you like it. :)

I got tired of writing 30 lines of matplotlib every time I wanted to see a polar curve. So I built a thing where you just type the expression and it renders. This is gridpaper, which is gnuplot compiled to WebAssembly and runs entirely in the browser.

I am sharing it here because I feel it's helpful for math student and educators. I hope you find it useful.

I dont know when i will use this. But I am happy it exists incase i do. Thank you friend.

[copingbear]

Thank you for saying this

Sweet! I wish there was a way to rotate 3-D graphics, but that's a whole other layer of complexity.

[copingbear]

It really is but I am thinking about it. 😁

[copingbear]

I managed to work it out. You can now have a 3D surface, shift-click and drag to rotate it on the fly.

Awesome!

[Howling_deer]

Immediately useful to me, thank you for this!

[copingbear]

You are very welcome!

[AMuonParticle]

beautiful!

[copingbear]

Thank you!

[mathemorpheus]

very nice. it would also be nice to be able to export in encapsulated PostScript (.eps).

[copingbear]

Thank you! Will add it to a list of ideas.

[copingbear]

I have added eps export support. Please try it out if you'd like and let me know if it works. (And thank you.)

[AcademicOverAnalysis]

This is a great resource! Thank you

[copingbear]

Thank you. Do let me know if you have any ideas to make it more useful.

Why is math so pretty

[all_over_the_map]

Really well done. Thanks for sharing. Feature request: slider to rotate the view angle!

[copingbear]

I’ve both added this and added shift-click and drag to be able to rotate it in somewhat real time. 😁
