- - Function Plot
-

- A 2d function plotter powered by D3 - -
-
- -
-

- Function Plot is a plotting library built on top of D3.js - used to render functions with little configuration (think of it as a clone of Google's - plotting utility: $y = x ^ 2$) -

-

- The library currently supports interactive line charts and scatterplots, - whenever the graph scale is modified the function is evaluated again with - the new bounds, result: infinite graphs! -

-

- -

- -

- Function Plot unlike other plotters that use $n$-equally spaced points joined by line segments - uses interval-arithmetic to - correctly determine sections of the screen that need to be plotted with a few samples -

-

- Most naive plotters will have problems plotting functions that oscillate too rapid, - for example $f(x) = sin(e^x)$ oscillates rapidly when $x > 5$, no matter how many times the - function is evaluated we will never be able to render this function correctly -

-

- -

- -

- Function Plot will instead evaluate the function using interval math which means that when - a rectangle whose $x$ bounds are $[x_i, x_{i + 1}]$ appears on the screen it's ensured that it - contains all the possible $f(\xi)$ for $\xi \in [x_i, x_{i+1}]$, the result: pixel perfect - representation of curves -
