KPI Gauge

[troseberry]

***Update***
Added support for new ExtJs 4.2.0
Series - KPIGauge
- Updated to be capatible with ExtJs 4.2.0
- Updated needle configuration to allow as optional
- Apply onAnimate method to the needle, needlePivot, and value sprites to correctly redraw location on animated resize of chart.
Axis - KPIGauge
- Update "drawAxis" method to allow for axis to inherit the applied chart theme, which by default is "Base"
- Update "drawLabel" method to allow for user customized/theme styling of labels. Default library method hard codes color, font.
- set "position: 'left'" in order to allow the axis to inherit the applied chart theme. Defaults to the "Base" theme.
- if you define "position: 'gauge'" then it will use default colors and font as defined in Ext.draw.Surface



Heres a small proof of concept extension I created for the Chart's Gauge series. It allows you to specify the different slice ranges with start, end, and color. Also contains the ability to specify the needle width, color and pivot point attributes as well.

nice work, thanks!

[Muhammad Hamid]

Can you give me files which you include in your Gauge.html
ext-all.css
example.css
bootstrap.js
example-data.js

I need these files because gauges are not shown to me due to missing of these files
thank you

[troseberry]

You need to download the latest ExtJs Library and just drop the files in the chart example folder and then open the gauge.html file

[Muhammad Hamid]

Thanks dear

but there is issue needle view is not showing properly as in your sacreenshot and colours are not diplayed only one colour is displayed on whole gauge

Hi Troseberry,

I am using your KPI gauge,But my panel has and expand/collapse capability ,show when i expand

the panel pivot is moving some where,please give me a solution....

[troseberry]

Can you please post a copy of the code that your using. I have tried to duplicate any issues using a collapsible panel and it seems to be working for me with no issues.

[mikegriffinn@gmail.com]

Have you done any more work on this? We're building an awesome dashboard app with an easy user UI to map grids that we create by importing spreadsheets to the widget code. It looks like your code will be a great basis for adding gauge widget. You can get and idea of what we are doing at http://www.otusanalytics.com/. We offer a free 3 dashboard instance so you can signup and check it out to get an idea of what we are doing. Thanks for posting this code!!

Just a quick modification/bug fix:

at about line 162, probably should set the pivot sprite's attributes again inside "if (animate)"

me.needlePivotSprite.setAttributes({
    type: 'circle',
fill: me.needle.pivotFill || '#222',
radius: me.needle.pivotRadius || 7,
x: centerX,
y: centerY
});

Otherwise, the pivotSprite will just remain where it is at~


I am still figuring out why sometimes the step marks just warp out of position or disappear. Anyone figured this out?

Many Thanks
