Getting an Object Reference to a Chart

[oneworld]

How does one get a reference to an existing chart. Let say I have created a chart during the window.onload() event. Later, e.g. following a user configuration change request, I want to modify the chart configuration. How to I proceed to get a reference to the existing chart from outside the window.onload() event or from outside the method in which it was originally defined?

@oneworld,

You can get the reference of the chart object outside of the window.onload() or any other function by either creating chart as a global variable, which is not a neat way to access the chart. Or you could pass the chart object as a parameter to the function that can access the chart as shown in this jsfiddle.
