graph_expression
Create a live graph of y = f(x). Give latex (a new equation object is created above the graph) or equationId (plot an existing equation). Optional named parameters (e.g. {a: 1}), tangent marker, shaded integral, gamma-density view with bin edges. Graphs re-plot when their equation changes.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
latex |
string | no | LaTeX in x, e.g. "x^2-2x-1" or "a x e^{x}". Give this or equationId, not both. |
equationId |
string | no | Id of an existing equation object to plot instead of latex. |
bounds |
object | no | Graph box in world px. Default {x: 730, y: 150, width: 460, height: 330}. |
parameters |
object | no | Named constants used by the LaTeX, e.g. {"a": 1.5}. |
showTangentAt |
number | no | x value at which to draw the tangent line. Optional. |
shadeIntegral |
array | no | [from, to] in x to shade the area under the curve, e.g. [0, 1]. |
visualization |
string | no | "standard" (default) or "gamma-density" for the normalised Gamma density view with mass bins. |
binEdges |
array | no | Four ascending x edges splitting the density into three masses, e.g. [0, 2.5, 5, 12]. gamma-density only. |
construct |
boolean | no | true: create it unbuilt (drawProgress 0), then animate drawProgress 0 to 1 on a timeline to build it on screen. Ink draws stroke by stroke. |
