Enter an equation in x and y — it is solved for y and plotted for x = 1 … 100, with (0,0) at the centre of the graph. Functions: sin cos tan asin acos atan atan2(y,x) sinh cosh tanh log ln log10 log2 sqrt cbrt exp abs floor ceil round sign (+ e, pi). Each row takes two colours — the line fades from the first into the second — plus its own thickness (px), a pen (pen: Technical, Pencil, Marker, Calligraphy, Highlighter) and a line style (style: solid, dashed, dotted, dash-dot, long dash). Drag to pan, scroll or pinch to zoom, double-click to reset.
