# Providing Chart Data

A Visualforce chart binds to the source of its data through the data attribute on the `<apex:chart>` component.

Data can be provided several different ways:

-   As [an expression that represents a controller method reference](https://developer.salesforce.com/docs/platform/salesforce-pages-developers-guide/guide/pages-charting-overview-providing-data-controller-method.md)
-   As [a string representing a JavaScript function](https://developer.salesforce.com/docs/platform/salesforce-pages-developers-guide/guide/pages-charting-overview-providing-data-javascript-function.md)
-   As [a string representing a JavaScript array](https://developer.salesforce.com/docs/platform/salesforce-pages-developers-guide/guide/pages-charting-overview-providing-data-javascript-array.md)
