This topic demonstrates how to bind data to the igFinancialChart control. At the end of each section, a complete code sample is provided.
This topic contains the following sections:
The procedure below demonstrates how to bind the igFinancialChart control to a data collection. The igFinancialChart allows you to bind to JavaScript arrays. Nested collections are also supported.
The igFinancialChart cannot plot multiple data sources on the XAxis in Time mode if the number of items in the data sources is not the same. The control also will not align items of multiple data sources when the XAxis is in Time mode. As a result, developers should align data items by inserting null items where one data source does not have corresponding items with another data source.
The ChartType property enables you to choose which series type you wish to display.
Supported series types:
Bar
Candle
Column
Line
The igFinancialChart control as implemented by the binding to data sample code:
Defining a Data Model
Adding an Instance of the igFinancialChart control
(Optional) Verifying the result
Define Data
In JavaScript
function getMultiData() {
var data = [];
data.push(PriceData.AMZN());
data.push(PriceData.GOOG());
data.push(PriceData.MSFT());
data.push(PriceData.TGT());
data.push(PriceData.TSLA());
return data;
}Add an instance of the igFinancialChart Control
Add an instance of the igFinancialChart and bind it to the data:
In HTML
<div id="chart" style="width:800px;height:600px"></div>In JavaScript
$(function () {
var data = getMultiData();
$("#chart").igFinancialChart({
dataSource: data
});
});(Optional) Verify the Result
Run your application to verify the result. If you have successfully bound the igFinancialChart control to the data collection, the resulting chart will look like the one shown above.
