Update new Data to the Chart in 2.0Rc1 - rally

Question

Here's the sample code
I tried with update and other functions, none of them worked
launch: function() {
var categories = ['EMEA','APAC','AMERICAS'],
name = 'Browser brands',
data = [{
y: 55.11,
drilldown: {
name: 'EMEA versions',
categories: ['Cost', 'TechMe', 'disc', 'Matt'],
data: [
{
y: 40.11,
drilldown: {
name: 'Cost Drill',
categories: ['Page 1', 'Page 2', 'Page 3.0', 'Page 4.0'],
data: [0.20, 0.83, 1.58, 13.12, 5.43]
}
},
{
y: 40.11,
drilldown: {
name: 'Techme Drill',
categories: ['Page 1', 'Page 2', 'Page 3.0', 'Page 4.0'],
data: [1.58, 13.12, 5.43,0.20, 0.83]
}
},
{
y: 40.11,
drilldown: {
name: 'dISC Drill',
categories: ['Page 1', 'Page 2', 'Page 3.0', 'Page 4.0'],
data: [0.83, 1.58, 13.12,0.20, 5.43]
}
}
]
}
}, {
y: 21.63,
drilldown: {
name: 'Firefox versions',
categories: ['Firefox 2.0', 'Firefox 3.0', 'Firefox 3.5', 'Firefox 3.6', 'Firefox 4.0'],
data: [0.20, 0.83, 1.58, 13.12, 5.43]
}
}, {
y: 11.94,
drilldown: {
name: 'Chrome versions',
categories: ['Chrome 5.0', 'Chrome 6.0', 'Chrome 7.0', 'Chrome 8.0', 'Chrome 9.0',
'Chrome 10.0', 'Chrome 11.0', 'Chrome 12.0'],
data: [0.12, 0.19, 0.12, 0.36, 0.32, 9.91, 0.50, 0.22]
}
}, {
y: 7.15,
drilldown: {
name: 'Safari versions',
categories: ['Safari 5.0', 'Safari 4.0', 'Safari Win 5.0', 'Safari 4.1', 'Safari/Maxthon',
'Safari 3.1', 'Safari 4.1'],
data: [4.55, 1.42, 0.23, 0.21, 0.20, 0.19, 0.14]
}
}, {
y: 2.14,
drilldown: {
name: 'Opera versions',
categories: ['Opera 9.x', 'Opera 10.x', 'Opera 11.x'],
data: [ 0.12, 0.37, 1.65]
}
}];
Here's the setChart function which is called on click event of the chart
function setChart(chart,name, categories, data, color) {
var newchart=mychart;
var chartConfig={
chart: {
type: 'column'
},
title: {
text: 'Browser market share, April, 2011'
},
subtitle: {
text: 'Click the columns to view versions. Click again to view brands.'
},
xAxis: {
categories: categories
},
yAxis: {
title: {
text: 'Total percent market share'
}
},
plotOptions: {
column: {
cursor: 'pointer',
point: {
events: {
click: function() {
var drilldown = this.drilldown;
if (drilldown) { // drill down
setChart(this,drilldown.name, drilldown.categories, drilldown.data, drilldown.color);
} else { // restore
setChart(this,name, categories, data);
}
}
}
},
dataLabels: {
enabled: true,
style: {
fontWeight: 'bold'
},
formatter: function() {
return this.y +'%';
}
}
}
},
tooltip: {
formatter: function() {
var point = this.point,
s = this.x +':<b>'+ this.y +'% market share</b><br/>';
if (point.drilldown) {
s += 'Click to view '+ point.category +' versions';
} else {
s += 'Click to return to browser brands';
}
return s;
}
}
}
console.log("Before ",newchart.chartConfig);
newchart.setChartConfig(chartConfig);
console.log("After ",newchart.chartConfig);
var chartSeries={
name: name,
data: data,
color: 'white'
}
newchart.setChartData(chartSeries);
chart.remove('#myChart');
//chart.update(newchart);
//redrawChart(this,mychart);
//console.log(mychart);
// console.log(chart.setChartConfig());
//chart.x.setCategories(categories, false);
//chart.chartData.series[0].remove(false);
/*chart.chartData.addSeries({
name: name,
data: data,
color: color || 'white'
}, false);*/
//chart.redraw();
// mychart.update();
//mychart.updateLayout();
// mychart.show();
console.log("After " , mychart);
}
Main chart is here ...
var mychart=Ext.create('Rally.ui.chart.Chart', {
autoRender:true,
autoShow:true,
id:'myChart',
storeType : 'Rally.data.WsapiDataStore',
storeConfig : {
model: 'Defect'
//fetch : ["_ValidFrom", "_ValidTo", "10778908645", "ScheduleState", "Name"]
//filters : this.getColumnFilters()
},
calculatorType: 'My.Calculator',
calculatorConfig: {},
chartConfig: {
chart: {
type: 'column'
},
title: {
text: 'Browser market share, April, 2011'
},
subtitle: {
text: 'Click the columns to view versions. Click again to view brands.'
},
xAxis: {
categories: categories
},
yAxis: {
title: {
text: 'Total percent market share'
}
},
plotOptions: {
column: {
cursor: 'pointer',
point: {
events: {
click: function() {
var drilldown = this.drilldown;
if (drilldown) { // drill down
setChart(this,drilldown.name, drilldown.categories, drilldown.data, drilldown.color);
} else { // restore
setChart(this,name, categories, data);
}
}
}
},
dataLabels: {
enabled: true,
style: {
fontWeight: 'bold'
},
formatter: function() {
return this.y +'%';
}
}
}
},
tooltip: {
formatter: function() {
var point = this.point,
s = this.x +':<b>'+ this.y +'% market share</b><br/>';
if (point.drilldown) {
s += 'Click to view '+ point.category +' versions';
} else {
s += 'Click to return to browser brands';
}
return s;
}
}
},
chartData:{ // this works
series: [{
name: name,
data: data,
color: 'white'
}],
exporting: {
enabled: false
}
}
});
// add your code here
this.add(mychart); // add the component to rally interface
}
I want data to get changed on clicking

Answer 1

I have an example of chart update triggered by a button click in a github repo here.
Unlike a AppSDK2 grids that have a reconfigure method, AppSDK charts do not. In this example I delete a chart this.down("#myChart").removeAll() , modify metric definition of the calculator and then re-add the chart to the app.
