Let’s write a reusable ember view for rendering graphs and charts powered by highcharts.
App.HighChartsView = Ember.View.extend
tagName: 'div'
classNames: [ 'highcharts' ]
chartConfig = {}
setConfig: (type)->
config = {
chart:
type: type
title:
text: @title || 'Highcharts'
xAxis:
categories: @dataset.categories || []
yAxis:
title:
text: @yAxisTitle
series: @series()
}
# Merge highcharts config if it is present
Ember.merge(config, @highChartConfig) if @highChartConfig
@set('chartConfig', config)
series: ->
@dataset.data
prepareConfig: ->
# if custom config is present then directly set it to chartConfig
if @customHighChartConfig
@set('chartConfig', @customHighChartConfig)
else
type = @type || 'line'
@setConfig(type)
didInsertElement: ->
@prepareConfig()
@renderHighchart()
renderHighchart: ->
@$().highcharts(@chartConfig)
Usage:
{{ view App.HighChartsView dataset=dataset title="Sample Analytics" type="line" yAxisTitle="Temperature C" }}
The dataset can be set at controller or may be at route.
App.IndexController = Ember.ArrayController.extend
dataset: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun','Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
data: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
}
Usage with control over config
{{ view App.HighChartsView dataset=dataset highChartConfig=highChartConfig title="Sample Analytics" type="line" }}
App.IndexController = Ember.ArrayController.extend
highChartConfig: {
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
}
}
