ZeGrapher v4: modern math plotter

What it does

A free and open source math plotter, easy to pick up. It draws functions, sequences, parametric equations and data in the plane. ZeGrapher draws mathematical objects in the plane — functions, sequences, parametric equations and data — and exports exactly what you see. The graph is what you see on the right, and what you export. The Grid and Graph tabs set its look, its precision and its size. On a touchpad or a touchscreen, a pinch zooms both axes too. The four fields at the top of the panel are the bounds of the view. Under them are five tabs: The four fields at the top of the panel accept expressions, not just numbers. A minimum must stay below its maximum, and the field turns invalid if…from zegrapher.com

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client.
