/** * @class Ext.chart.series.Radar * @extends Ext.chart.series.Polar * * Creates a Radar Chart. A Radar Chart is a useful visualization technique for comparing different quantitative values for * a constrained number of categories. * As with all other series, the Radar series must be appended in the *series* Chart array configuration. See the Chart * documentation for more information. A typical configuration object for the radar series could be: * * @example * Ext.create({ * xtype: 'polar', * renderTo: document.body, * width: 500, * height: 400, * interactions: 'rotate', * store: { * fields: ['name', 'data1'], * data: [{ * 'name': 'metric one', * 'data1': 8 * }, { * 'name': 'metric two', * 'data1': 10 * }, { * 'name': 'metric three', * 'data1': 12 * }, { * 'name': 'metric four', * 'data1': 1 * }, { * 'name': 'metric five', * 'data1': 13 * }] * }, * series: { * type: 'radar', * angleField: 'name', * radiusField: 'data1', * style: { * fillStyle: '#388FAD', * fillOpacity: .1, * strokeStyle: '#388FAD', * strokeOpacity: .8, * lineWidth: 1 * } * }, * axes: [{ * type: 'numeric', * position: 'radial', * fields: 'data1', * style: { * estStepSize: 10 * }, * grid: true * }, { * type: 'category', * position: 'angular', * fields: 'name', * style: { * estStepSize: 1 * }, * grid: true * }] * }); * */Ext.define('Ext.chart.series.Radar', { extend: 'Ext.chart.series.Polar', type: 'radar', seriesType: 'radar', alias: 'series.radar', requires: ['Ext.chart.series.sprite.Radar'], themeColorCount: function() { return 1; }, isStoreDependantColorCount: false, themeMarkerCount: function() { return 1; }, updateAngularAxis: function (axis) { axis.processData(this); }, updateRadialAxis: function (axis) { axis.processData(this); }, coordinateX: function () { return this.coordinate('X', 0, 2); }, coordinateY: function () { return this.coordinate('Y', 1, 2); }, updateCenter: function (center) { this.setStyle({ translationX: center[0] + this.getOffsetX(), translationY: center[1] + this.getOffsetY() }); this.doUpdateStyles(); }, updateRadius: function (radius) { this.setStyle({ endRho: radius }); this.doUpdateStyles(); }, updateRotation: function (rotation) { this.setStyle({ rotationRads: rotation }); this.doUpdateStyles(); }, updateTotalAngle: function (totalAngle) { this.processData(); }, getItemForPoint: function (x, y) { var me = this, sprite = me.sprites && me.sprites[0], attr = sprite.attr, dataX = attr.dataX, length = dataX.length, store = me.getStore(), marker = me.getMarker(), threshhold, item, xy, i, bbox, markers; if (me.getHidden()) { return null; } if (sprite && marker) { markers = sprite.getMarker('markers'); for (i = 0; i < length; i++) { bbox = markers.getBBoxFor(i); threshhold = (bbox.width + bbox.height) * .25; xy = sprite.getDataPointXY(i); if (Math.abs(xy[0] - x) < threshhold && Math.abs(xy[1] - y) < threshhold) { item = { series: me, sprite: sprite, index: i, category: 'markers', record: store.getData().items[i], field: me.getYField() }; return item; } } } return me.callParent(arguments); }, getDefaultSpriteConfig: function () { var config = this.callParent(), fx = { customDurations: { translationX: 0, translationY: 0, rotationRads: 0, // Prevent animation of 'dataMinX' and 'dataMaxX' attributes in order // to react instantaniously to changes to the 'hidden' attribute. dataMinX: 0, dataMaxX: 0 } }; if (config.fx) { Ext.apply(config.fx, fx); } else { config.fx = fx; } return config; }, getSprites: function () { var me = this, chart = me.getChart(), animation = me.getAnimation() || chart && chart.getAnimation(), sprite = me.sprites[0], marker; if (!chart) { return []; } if (!sprite) { sprite = me.createSprite(); } if (animation) { marker = sprite.getMarker('markers'); if (marker) { marker.getTemplate().setAnimation(animation); } sprite.setAnimation(animation); } return me.sprites; }, provideLegendInfo: function (target) { var me = this, style = me.getSubStyleWithTheme(), fill = style.fillStyle; if (Ext.isArray(fill)) { fill = fill[0]; } target.push({ name: me.getTitle() || me.getYField() || me.getId(), mark: (Ext.isObject(fill) ? fill.stops && fill.stops[0].color : fill) || style.strokeStyle || 'black', disabled: me.getHidden(), series: me.getId(), index: 0 }); } });
