View Full Version : Total in Title of Bar Chart

9 Nov 2009, 8:30 AM
I have a bar chart that is loading data from a jsonStore without any problems.

I would like to add the total of the store, or a specifc value from the store to the title. This is where I am having problem.

My store has counts of vehicles in a current location and an ID number for my reference.

Here is a sample of my store for reference:

{"vdloc":"New Arrival","n":"3","id":"1"},
{"vdloc":"Frame Receipt","n":"14","id":"3"},
{"vdloc":"Open Units","n":"0","id":"146"},
{"vdloc":"Assembly Receipt","n":"2","id":"7"},
{"vdloc":"Main Line","n":"8","id":"9"},
{"vdloc":"Assembly CEPOS","n":"6","id":"11"},
{"vdloc":"Paint Repair","n":"0","id":"112"},
{"vdloc":"Quality Assessment","n":"0","id":"12"},
{"vdloc":"Ready to Ship","n":"3","id":"13"},
{"vdloc":"Sales Hold","n":"7","id":"18"},
{"vdloc":"Off Site","n":"6","id":"105"},

Here is the start of my chart:

new Ext.Panel({
frame: true,
title: 'Graphical Vehicle Distribution ',
renderTo: 'container',
width: 600,
height: 300,

I'd like to make the title "Graphical Vehicle Distribution (34)" or however many vehicles are in the store. I've tried sum('n') with no luck. Any help would be appreciated.

What's the difficulty? Add a load listener to the Store which calls setTitle on the Panel.
