Usage (signatures)
board.create('boxplot', [quantiles, axis, width]);
Parameters
| Name | Type | Description |
|---|---|---|
quantiles |
Array | Array containing five quantiles (e.g. min, first quartile, median, third quartile, maximum) and an optional array with outlier values. The elements of this array can be of type number, function or string. The optional aub-array outlier is an array of numbers or a function returning an array of numbers. |
axis |
Number | function | Axis position of the boxplot |
width |
Number | function | Width of the rectangle part of the boxplot. The width of the first and 3th quartile is relative to this width and can be controlled by the attribute "smallWidth". |
Examples
Vertical boxplot with user-supplied quantiles
var Q = [ -1, 2, 3, 3.5, 5 ];
var b = board.create('boxplot', [Q, 2, 4], {strokeWidth: 3});
Horizontal boxplot with user-supplied quantiles and outliers
var Q = [ -1, 2, 3, 3.5, 5, [-4, -6] ];
var b = board.create('boxplot', [Q, 3, 4], {
dir: 'horizontal',
width: 2,
smallWidth: 0.25,
color:'red'
});
Boxplot, quantiles computed with `JXG.Math.Statistics.boxplot()`
var data = [57, 57, 57, 58, 63, 66, 66, 67, 67, 68, 69,
70, 70, 70, 70, 72, 73, 75, 75, 76, 76, 78, 79, 81];
var Q = JXG.Math.Statistics.boxplot(data);
var b = board.create('boxplot', [Q, 0, 3]);
Boxplot with dynamic quantiles
var mi = board.create('glider', [0, -1, board.defaultAxes.y]);
var ma = board.create('glider', [0, 5, board.defaultAxes.y]);
var Q = [() => mi.Y(), 2, 3, 3.5, () => ma.Y()];
var b = board.create('boxplot', [Q, 0, 2]);
Attributes

dir
- Description
Direction of the boxplot: 'vertical' or 'horizontal'

outlier
- Description
Size and face of outliers. Size is the point size in pixel. Possible values for face are 'o' (default), '[]', '<>', '<<>>', '+', 'x', '-', '|'. See JXG.Grid for these names ('o' here is 'regpol' of the grid).
