3.6 Plot

Plot

The plot displays a function plot for a mathematical single-variable expression.

Extends:

• Component

Implements:

• none

Parameters:

Required:

• func: string A mathematical expression as a string that will be parsed when calculating the plot points.

Optional:

• numPoints?: number The number of points to use when approximating the graph. This should be left untouched unless serious performance issues occurs, or the plot is too inaccurate.
• dashed?: boolean Whether the plot should be dashed.
• lineWidth?: number Linewidth of the plot.
• color?: number Color of the graph line.
• coefficients?: Coefficients Any coefficients that was used in the function string should be specified with a value here.
• plotRange?: number How far the plot should extend on each side of the x-axis. Should be left untouched. Use plotBetween instead.
• plotBetween: [number, number] | undefined: Two x-values to plot the graph between.

Extra types:

• Coefficients = { [key: string]: number; }

Default Parameters:

numPoints: 1500,
dashed: false,
lineWidth: 4,
color: 0xfaa307,
coefficients: {},
plotBetween: undefined,

Implemented Methods:

• none

Methods

• setCoefficients(coefficients: Coefficients): void Set the coefficients to a specified value. Will re-render the graph accordingly.
• setExpression(expression: string): void Set the function expression to a specified string value. Will re-render the graph accordingly.
