Graphing & Plotting
Plot functions, set ranges, layer multiple curves, and add sliders.
Type plot (or graph) in front of an expression and Instacalc draws it. The
graph is live — it re-renders as you edit the formula or drag a slider.
Plot a function
Any expression in x works. Use plot or graph — they’re the same.
Set the range
By default the x-axis runs from −10 to 10. Add from … to … to set your own
window:
Layer multiple curves
List expressions separated by commas to overlay them on one chart. Each curve gets its own color and the legend labels them.
Sliders
Annotate a row with a range to turn a constant into a draggable slider, then reference it in your plot. The slider updates the graph in real time — drag it:
Here m = 1 // -5..5 creates a slider from −5 to 5 (starting at 1), and the
line m*x re-slopes as you drag.
The graph view
Any calc can open in a dedicated full-screen graph view. Append /graph to a
calc URL (e.g. instacalc.com/<id>/graph), or switch the view mode from the
calc itself. See Sharing for the URL view-tail forms.
