/** * A box plot chart is a useful tool for visializing data distribution within datasets. * For example, salary ranges for a set of occupations, or life expectancy for a set * of countries. A single box with whiskers displays the following values for a dataset: * * * minimum * * lower quartile (Q1) * * median (Q2) * * higher quartile (Q3) * * maximum * * For example: * * @example * Ext.create({ * xtype: 'cartesian', * width: 400, * height: 400, * renderTo: Ext.getBody(), * insetPadding: '20 20 10 10', * store: { * data: [{ * category: 'Engineer IV', * low: 110, q1: 130, median: 175, q3: 200, high: 225 * }, { * category: 'Market', * low: 75, q1: 125, median: 210, q3: 230, high: 255 * }] * }, * axes: [ * { * type: 'numeric', * position: 'left', * renderer: function (axis, text) { * return '$' + text + ' K' * } * }, * { * type: 'category', * position: 'bottom' * } * ], * series: { * type: 'boxplot', * xField: 'category', * style: { * maxBoxWidth: 50, * lineWidth: 2 * } * } * }); * */Ext.define('Ext.chart.series.BoxPlot', { extend: 'Ext.chart.series.Cartesian', alias: 'series.boxplot', type: 'boxplot', seriesType: 'boxplotSeries', isBoxPlot: true, requires: [ 'Ext.chart.series.sprite.BoxPlot', 'Ext.chart.sprite.BoxPlot' ], config: { itemInstancing: { type: 'boxplot', animation: { // Setting the duration of these attributes to zero because // the 'data' attributes of the series sprite (MarkerHolder) // will be animated instead, and then changes applied to // the attributes of 'boxplot' instances instantly. customDurations: { x: 0, low: 0, q1: 0, median: 0, q3: 0, high: 0 } } }, /** * @cfg {String} [lowField='low'] * The name of the store record field that represents the smallest value of a dataset. */ lowField: 'low', /** * @cfg {String} [q1Field='q1'] * The name of the store record field that represents the lower (1-st) quartile * value of a dataset. */ q1Field: 'q1', /** * @cfg {String} [medianField='median'] * The name of the store record field that represents the median of a dataset. */ medianField: 'median', /** * @cfg {String} [q3Field='q3'] * The name of the store record field that represents the upper (3-rd) quartile * value of a dataset. */ q3Field: 'q3', /** * @cfg {String} [highField='high'] * The name of the store record field that represents the largest value of a dataset. */ highField: 'high' }, fieldCategoryY: ['Low', 'Q1', 'Median', 'Q3', 'High'], updateXAxis: function (xAxis) { xAxis.setExpandRangeBy(0.5); this.callParent(arguments); }});
