Gauge chart with needle

[Syntona]

Hi,

I am trying to create Gauge chart with needle.
I have used config parameter "needle:true",
However I can see the needle but the chart is in one color only (only 1 slice is added).

Is it by design or some bug in it.

Attached image is 2 gauge chart with and without needle.


Thanks in advance

Can I get a test case for this? Development has ceased on Touch Chart beta so bugs will not be fixed. We are only developing ST2 charts in ST 2.1.0+

            {   
                xtype: 'titlebar',
                docked: 'bottom',
                title: 'KPI',
            }
        ]
    });

I hope it will help.

Hi,

I'm working on Ext JS version 4.1 and same thing is happening with me as well.
When I don't make use of needle attribute, I get 2 slices in a Gauge chart in 2 different colors but when I specify needle attribute, entire Gauge chart gets changed to only one color.

Please see attached image.

Any assistance here please.

Sample code is mentioned as below:Ext.require(['Ext.chart.*', 'Ext.chart.axis.Gauge', 'Ext.chart.series.*', 'Ext.Window','Ext.chart.Label','Ext.draw.Color','Ext.draw.*']);
var myStore = Ext.create('Ext.data.ArrayStore', {
fields: [
{name: 'chapters', type: 'int'}
],
data: [['20'],['34']]
});
Ext.onReady(function () {
Ext.create('Ext.Window', {
width: 500,
height: 500,
minWidth: 500,
minHeight: 500,
title: 'Gauge Charts',
layout: {
type: 'hbox',
align: 'stretch'
},
items: [{
xtype: 'chart',
style: 'background:blue',
store: myStore,
insetPadding: 25,
flex: 1,
axes: [{
type: 'gauge',
position: 'gauge',
minimum: 0,
maximum: 100,
steps: 10,
margin: -10
}],
series: [{
type: 'gauge',
field: 'chapters'
//donut: 30,
//needle: true,
//colorSet: ['yellow', '#ddd']
}],
series: [{
type: 'gauge',
field: 'chapters'
//donut: 30,
//needle: true,
//colorSet: ['green', '#ddd']
}]
}]
}).show();
});

Regards,
Rohit
