View Full Version : Beginner needs help getting chart going

26 Apr 2012, 1:59 AM

I'm working on converting the example Pie chart into a working, database based version. I have setup an Ajax/ JSON store like this:

Ext.define('Chart', {
extend: 'Ext.data.Model',
fields: ['name', 'value']

//The Store contains the AjaxProxy as an inline configuration
var store = Ext.create('Ext.data.Store', {
model: 'Chart',
proxy: {
type: 'ajax',
url : '/backend/report/data'


my data comes from here: http://analyser.automatem.co.nz/backend/report/data

One of the confusing items is that the example uses many data series, I can only see that I need one to show a pie chart with 3 pieces.

When I load the whole chart, I get the legend, but the image seems to only have a little bit in the top left corner. I checked if this is an issue with SVG display here: http://www.webpagetest.org/result/120426_NF_43F05/ and while this looks differently, it seems to be wrong as well.

Can anyone give me tips to get over this hurdle?

Thanks in advance,

My guess would be you're not setting a height/width for your chart. If you wish to have the chart stretch to an unknown width, you need to embed the chart inside a panel with a 'fit' layout.
