sencha touch and charts - graph

Question

Has anyone been able to incorporate Charts and graphs into Sencha Touch?
If so, an example would be appreciated.
Thanks

Answer 1

Sencha Touch Charts has just been released

Answer 2

I was under the impression that Raphael (http://raphaeljs.com/) would eventually be incorporated into Sencha Touch for its' graphing component (http://g.raphaeljs.com/). Until then, you can pretty easily just include the extra Raphael .js files and make graphs that way. Something like:
<script src="sencha-touch-1.0/sencha-touch-debug.js" type="text/javascript" charset="utf-8"></script>
<!-- Raphael JS -->
<script src="raphael/raphael-min.js" type="text/javascript" charset="utf-8"></script>
<script src="raphael/g.raphael-min.js" type="text/javascript" charset="utf-8"></script>
<script src="raphael/g.pie-min.js" type="text/javascript" charset="utf-8"></script>
<script src="raphael/g.line-min.js" type="text/javascript" charset="utf-8"></script>
<script src="raphael/g.bar-min.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript" charset="utf-8">
Ext.setup({
onReady: function()
{
// Set up main panel!
var tabPanel = new Ext.Panel
({
fullscreen: true,
html: '<div id="graph"></div>'
});
// Try to draw a graph!
var r = Raphael('graph');
r.g.txtattr.font = '12px Helvetica, Arial, sans-serif';
r.g.text(150, 250, "Demo chart with title");
r.g.linechart(10, 10, 300, 220, [[1, 2, 3, 4, 5, 6, 7],[3.5, 4.5, 5.5, 6.5, 7, 8]], [[12, 32, 23, 15, 17, 27, 22], [10, 20, 30, 25, 15, 28]], {nostroke: false, axis: "0 0 1 1", symbol: "o", smooth: true});
}
});
</script>

Answer 3

Take a look at http://code.google.com/p/oppo-touching/. Someone already moved charting to Snecha Touch. Also there is news that next version of Sencha Touch will include charting.

Answer 4

they now have some examples. they should help http://dev.sencha.com/deploy/touch-charts-beta/examples/

Answer 5

Here's the code for a sample chart in Sencha Touch
var SampleLineChart = new Ext.chart.Chart({
fullscreen : true,
iconCls: 'line',
cls: 'chartpanel',
theme: 'Energy',
interactions: [ 'reset',
{
type: 'panzoom',
axes: {
right: {}
}
},
{
type: 'iteminfo',
gesture: 'tap',
listeners: {
show: function(interaction, item, panel) {
// Ext.dispatch({
// controller : 'Users',
// action : 'popupInfoAbtChart',
// data : {item:item, panel:panel}
// });
}
}
}],
animate: false,
store: EnergyApp.stores.ChartStore, //choose for consumption
axes: [{
type: 'Numeric',
position: 'right',
minimum: 0,
majorTickSteps : 10,
minorTickSteps : 5,
fields: ['generatedpv', 'buildcons','excessPV'],
title: 'Y-axis title'
},
{
type: 'Category',
position: 'bottom',
fields: ['day'],
title: 'X-axis title',
label: {
rotate: {
degrees: 45
}
}
}],
legend: {
position: Ext.is.Phone ? 'left' : 'top'
},
series: [{
type: 'line',
highlight: false,
showMarkers: true,
fill: false,
smooth: true,
axis: 'right',
xField: 'day',
yField: 'generatedpv',
title: 'Field 1
},
{
type: 'line',
highlight: false,
showMarkers: true,
fill: false,
smooth: true,
axis: 'right',
xField: 'day',
yField: 'buildcons',
title: 'Field 2
}],
listeners: {
afterrender: function(me) {
me.on('beforerefresh', function() {
if (me.ownerCt.getActiveItem().id !== me.id) {
return false;
}
}, me);
}
}
});
For more code examples take a look at the EnergyApp Example in the Sencha-Touch-Charts example folder. Its been depicted quite well

Answer 6

Here is a link to a Sencha forum with some examples of how to incorporate a chart into an existing Sencha Touch 2.0 application:
http://www.sencha.com/forum/showthread.php?190053-How-to-Integrate-Touch-2-Charts-into-an-existing-Sencha-Touch-2.0-Final-application.

Answer 7

The package with the chart api for Sencha exists ( http://dev.sencha.com/deploy/touch-charts-beta/examples/) but appears very hard to integrate in the sencha touch solution (files dependency, function not defined in some version of the sencha touch package).
The solution I found is to install the trial version of Sencha Architect which already include the graph api, create a mobile project (touch project) and package it. Then I have a whole package with the right dependencies and I can reuse it without depending on Sencha Architect.
