loading json data How to show clustered bar charts in dynamic graphs - codeigniter

Question

Updated
Can you possible graphs value dynamic.
Below code pass a static value but i get dynamic code graphs.
Example: resultx get 3-4 subcategory i every time define graphs value.
var processedChartData = resultx.map(function(rawDataElement) {
var newDataElement = { "category": rawDataElement.category };
rawDataElement.data.forEach(function(nestedElement, index) {
newDataElement["value" + index] = nestedElement.value;
newDataElement["subcategory" + index] = nestedElement.subcategory
});
return newDataElement;
});
AmCharts.makeChart(id, {
"type": "serial",
"theme": "light",
"categoryField": "category",
"rotate": false,
"startDuration": 0,
"categoryAxis": {
"gridPosition": "start",
"position": "left"
},
"graphs": [{
"fillAlphas": 0.9,
"lineAlpha": 0.2,
"title": "2004",
"type": "column",
"balloonText": "[[subcategory0]]: [[value]]",
"valueField": "value0"
}, {
"fillAlphas": 0.9,
"lineAlpha": 0.2,
"title": "2005",
"type": "column",
"balloonText": "[[subcategory1]]: [[value]]",
"valueField": "value1"
},
{
"fillAlphas": 0.9,
"lineAlpha": 0.2,
"title": "2005",
"type": "column",
"balloonText": "[[subcategory2]]: [[value]]",
"valueField": "value2",
}],
"guides": [],
"allLabels": [],
"balloon": {},
"titles": [],
"dataProvider": processedChartData,
"export": {
"enabled":false
}
});
Original question:
Clustered bar charts Array inside key how to display multiple bar charts.
My json below:
[
{
"0":
{
"package_sold":"88",
"vSectorName":"Meat"
},
"country":"France"
},
{
"0":
{
"package_sold":"68",
"vSectorName":"Meat"
},
"1":
{
"package_sold":"151",
"vSectorName":"Poultry"
},
"country":"United Kingdom"
}
]
How to show in graph dataProvider

Answer 1

AmCharts doesn't support nested JSON. You'll need to flatten your JSON into a single object so that your valueFields are distinct in each element of your array.
For example, this:
{
"0":
{
"package_sold":"68",
"vSectorName":"Meat"
},
"1":
{
"package_sold":"151",
"vSectorName":"Poultry"
},
"country":"United Kingdom"
}
can be turned into this:
{
"Meat_package_sold": 68,
"Poultry_package_sold": 151,
"country": "United Kingdom"
}
From there you can set your graph valueField to "Meat_package_sold" and "Poultry_package_sold". I'm assuming your categoryField is "country".
You'll either need to change your backend or write some some JS to remap your data to a format that AmCharts can recognize.
Edit: Here's a basic example that remaps your JSON data using JS:
var rawData = [{
"0": {
"package_sold": "88",
"vSectorName": "Meat"
},
"country": "France"
},
{
"0": {
"package_sold": "68",
"vSectorName": "Meat"
},
"1": {
"package_sold": "151",
"vSectorName": "Poultry"
},
"country": "United Kingdom"
}
]
var newData = [];
rawData.forEach(function(dataItem) {
var newDataItem = {};
Object.keys(dataItem).forEach(function(key) {
if (typeof dataItem[key] === "object") {
newDataItem[dataItem[key]["vSectorName"] + "_package_sold"] = dataItem[key]["package_sold"];
} else {
newDataItem[key] = dataItem[key];
}
});
newData.push(newDataItem);
});
console.log(JSON.stringify(newData));
Demo of your chart using the correct JSON format:
var chart = AmCharts.makeChart("chartdiv", {
"type": "serial",
"theme": "light",
"categoryField": "country",
"graphs": [{
"fillAlphas": 0.8,
"lineAlpha": 0.2,
"type": "column",
"valueField": "Meat_package_sold"
},
{
"fillAlphas": 0.8,
"lineAlpha": 0.2,
"type": "column",
"valueField": "Poultry_package_sold"
}
],
"dataProvider": [{
"Meat_package_sold": 88,
"country": "France",
}, {
"Meat_package_sold": 68,
"Poultry_package_sold": 151,
"country": "United Kingdom"
}, {
"Meat_package_sold": 120,
"Poultry_package_sold": 110,
"country": "Germany"
}]
});

Answer 2

This is dynamic json data, but to show how to use and build I defined it so.
In actual, i use ajax to get json data and then building it dynamically.
Here I had Generate Graph,GLName against its opening for each month comparatively. hope it will helpful for all
var resp=[
