| A Theme defines the style of the shapes, color, font,
| axes and background of a chart.
| The theming configuration can be very rich and complex:
|
|
| {
| axis: {
| fill: '#000',
| 'stroke-width': 1
| },
| axisLabelTop: {
| fill: '#000',
| font: '11px Arial'
| },
| axisLabelLeft: {
| fill: '#000',
| font: '11px Arial'
| },
| axisLabelRight: {
| fill: '#000',
| font: '11px Arial'
| },
| axisLabelBottom: {
| fill: '#000',
| font: '11px Arial'
| },
| axisTitleTop: {
| fill: '#000',
| font: '11px Arial'
| },
| axisTitleLeft: {
| fill: '#000',
| font: '11px Arial'
| },
| axisTitleRight: {
| fill: '#000',
| font: '11px Arial'
| },
| axisTitleBottom: {
| fill: '#000',
| font: '11px Arial'
| },
| series: {
| 'stroke-width': 1
| },
| seriesLabel: {
| font: '12px Arial',
| fill: '#333'
| },
| marker: {
| stroke: '#555',
| fill: '#000',
| radius: 3,
| size: 3
| },
| seriesThemes: [{
| fill: '#C6DBEF'
| }, {
| fill: '#9ECAE1'
| }, {
| fill: '#6BAED6'
| }, {
| fill: '#4292C6'
| }, {
| fill: '#2171B5'
| }, {
| fill: '#084594'
| }],
| markerThemes: [{
| fill: '#084594',
| type: 'circle'
| }, {
| fill: '#2171B5',
| type: 'cross'
| }, {
| fill: '#4292C6',
| type: 'plus'
| }]
| }
|
| We can also create a seed of colors
| that is a base for the entire theme
| just by creating a simple array of colors
| in the configuration object like:
|
| {
| colors: ['#aaa', '#bcd', '#eee']
| }
|
| When setting a base color, the theme generates
| an array of colors that match the base color:
|
| {
| baseColor: '#bce'
| }
|
| You can create a custom theme by extending from the base theme.
| For example, to create a custom `Fancy` theme we can do:
|
| var colors = ['#555',
| '#666',
| '#777',
| '#888',
| '#999'];
|
| var baseColor = '#eee';
|
| Ext.define('Ext.chart.theme.Fancy', {
| extend: 'Ext.chart.theme.Base',
|
| constructor: function(config) {
| this.callParent([Ext.apply({
| axis: {
| fill: baseColor,
| stroke: baseColor
| },
| axisLabelLeft: {
| fill: baseColor
| },
| axisLabelBottom: {
| fill: baseColor
| },
| axisTitleLeft: {
| fill: baseColor
| },
| axisTitleBottom: {
| fill: baseColor
| },
| colors: colors
| }, config)]);
| }
| });
|
| var chart = Ext.create('Ext.chart.Chart', {
| theme: 'Fancy',
|
| /* Other options here... */
| });
|
|
