How to render series data to a title in sencha charts - javascript

I have a chart retrieving data from my store, the four bits of information are the following
Model Code
Ext.define('QvidiApp.model.ClipsViews', {
extend: 'Ext.data.Model',
requires: [
'Ext.data.Field'
],
config: {
fields: [
{
name: 'meta_id'
},
{
name: 'title'
},
{
name: 'viewed'
},
{
name: 'glances'
}
]
}
});
Now I have the viewed field and the glances field as the numeric fields in the chart, and the title field as the category title in the chart.
I want to render the title name of the field when I hover over it, reason id this. The titles are too long to fit in the x-axis of the chart so in place of the titles I am putting 'meta_id'. So when I hover over the x-axis meta_id field I want the title name to be shown
so for example
meta_id 100 will equal title value ###
Here's is my chart code so far
{
xtype: 'chart',
centered: true,
height: '150%',
colors: [
'#24ad9a',
'#7c7474',
'#a66111'
],
store: 'ClipsViewed',
axes: [
{
type: 'category',
fields: [
'meta_id'
],
grid: true,
label: {
rotate: {
degrees: 0
},
font: '7px'
},
title: 'Clips'
},
{
type: 'numeric',
fields: [
'viewed'
],
grid: true,
position: 'left',
title: 'Amount'
}
],
series: [
{
type: 'bar',
renderer: function(sprite, config, rendererData, index) {
},
style: {
minGapWidth: 1,
minBarWidth: 60,
maxBarWidth: 70,
opacity: 0.80
},
xField: 'meta_id',
yField: [
'viewed',
'glances'
]
}
],
interactions: [
{
type: 'panzoom'
}
],
legend: {
xtype: 'legend'
}
}
As you can see in the above code I have a render function but I dont know what to put into it

Use tips for series
series: [
{
type: 'bar',
tips: {
trackMouse: true,
width: 74,
height: 38,
renderer: function(storeItem, item) {
this.setTitle(storeItem.get('meta_id') + '<br />' + storeItem.get('title'));
}
},
style: {
minGapWidth: 1,
minBarWidth: 60,
maxBarWidth: 70,
opacity: 0.80
},
xField: 'meta_id',
yField: [
'viewed',
'glances'
]
}
]

Highcharts packed bubble chart not working for negative values

I am using High charts packed bubble chart and I need to show different sizes of bubbles according to its value (negative values). It is working fine when I pass positive values but size of the circle not changing when I pass negative values. Is there any way to show chart with negative values?
js fiddle link with code example
Highcharts.chart('container', {

graph with negative values
graph with positive values
Properties zMin and zMax are not a part of official packedbubble series API, but they are internally used and work as in bubble series.
plotOptions: {
packedbubble: {
minSize: '30%',
maxSize: '80%',
//zMin: 0,
//zMax: 1000,
...
}
}

Rendering json results to a pie chart in a div - highmaps

I have built this electoral map but I have not succeeded drawing a pie chart of the two parties on the pop-up dialog when a map region is clicked. The dialog title is being passed but not the actual values that should build the chat.
The returned json data is here and I just want to push a pie-chart to the dialog when someone clicks on a county on the map. Here's my code and "pointClick" function that should render the pie to a div.
$(function() {
$.getJSON("<?= base_url('index.php/presidential/getByCounty'); ?>", function(json) {
function pointClick(json) {
var row = this.options.row,
$div = $('<div></div>')
.dialog({
title: ([this.name]),
width: 400,
height: 300
});
//THIS IS ACTUALLY WHAT'S NOT WORKING
window.chart = new Highcharts.Chart({
chart: {
renderTo: $div[0],
type: 'pie',
width: 370,
height: 240
},
title: {
text: null
},
series: [{
name: 'Votes',
data: [{
name: 'nasa',

y: this.nasa //returned json data for candidate 1 and I problem must be somewhere here
}, {
name: 'jubilee',
color: '#C40401',
y: this.jubilee //returned json data for candidate 2
}],
dataLabels: {
// format: '<b>{point.name}</b> {point.value:.1f}%'
}
}]
});
}
//AM BUILDING THE ELECTORAL MAP FROM THIS POINT WHICH WORKS OUT NICELY
$('#presidential').highcharts('Map', {
title: {
text: 'Presidential Electoral Map <em>(Kenya - Test)</em>'
},

Your JSON data contains number in string format so convert it into Number
like this
Fiddle link
series: [{
name: 'Votes',
data: [{
name: 'nasa',
color: '#0200D0',
y: Number(this.nasa) //transform to number
}, {
name: 'jubilee',
color: '#C40401',
y: Number(this.jubilee) //transform to number
}],
dataLabels: {
format: '<b>{point.name}</b> {point.value:.1f}%'
}
}]

how to increase name in pie chart in extjs

when I use more then five letters in my name it comes out of the chart see the image i uploaded i am using extjs 6 I just want to have a large name on my chart
{
xtype: 'polar',
split: true,
flex: 0.3,
colors: [
'#347327',
'#2897d2',
'#de6110',
],
bind: {
store: '{pie}'
},
series: [{
type: 'pie',
showInLegend: true,
donut: false,
tips: {
trackMouse: true,
width: 140,
height: 28,
renderer: function(storeItem, item) {
this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data'));
}
},
highlight: {
segment: {
margin: 15
}
},
label: {
field: 'name',
display: 'rotate',
contrast: true,
font: '12px Arial'
},
xField: 'data'
}],
interactions: [{
type: 'rotate'
}]
}
here is My dynamically given names i want that names in side of my pie chart i mean above on the chart But when i use name that contain more then 5 letters it goes out side of the chart i will upload a image.
var pieStore = this.getViewModel().getStore('pie');
var rec = selected[0];
if (rec.get('new')) {
pieStore.add({
'name': 'NEW',
data: rec.get('new'),
total: rec.get('total')
});
}
if (rec.get('openToQc')) {
pieStore.add({
'name': 'QC',
data: rec.get('openToQc'),
total: rec.get('total')
});
}
if (rec.get('open')) {
pieStore.add({
'name': 'Open',
data: rec.get('open'),
total: rec.get('total')
});
}
if (rec.get('rejected')) {
pieStore.add({
'name': 'Rejected',
data: rec.get('rejected'),
total: rec.get('total')
});
}
The problem is on your series label:
label: {
field: 'name',
display: 'rotate',
contrast: true,
font: '12px Arial'
},
display: 'rotate', displays the label inside the chart in some cases and outside in others, you should use instead display: 'inside',
You can see a working example here

ExtJS 4.2.1.883: Bar Graph not plotted

});
Even though the values get plotted, the actual graph is not visible. I tried various examples with the same result. In Fiddle it works fine but in my code, the graph doesn't get plotted at all. Can someone help?

loading extjs bar chart sample into a div tag

Just a newbie here trying to understand and work on extjs 4.2.1. I really like the charts and grids and wanted to incorporate them into my current application. I got the sample grid to work in my application but the chart turns out to be a little harder. I used the sample code at
sample code
which renders the chart in another window and was wondering if someone can help me put this into a div tag on one of my panels.
Here is the container I have for the chart:
<div data-dojo-type="dijit.layout.ContentPane" data-dojo-props="splitter:false">
<div id="container"></div>
</div>
and the chart script: charts.js
Ext.require('Ext.chart.*');
Ext.require(['Ext.Window', 'Ext.fx.target.Sprite', 'Ext.layout.container.Fit']);
Ext.onReady(function () {
var textArea;
var store = new Ext.data.JsonStore({

});
You didn't explain what the problem was, however it's pretty clear from looking at the code.
The issue is that you need to give the chart a width/height, because it needs those to size appropriately. In the original example in the docs, the dimensions are provided explicitly by the fit layout used on the window.
