A variation of the FusionCharts and Javascript Example

Recommended Posts

Regarding the advanced example given in the document section called "FusionCharts and Javascript" (pasted below), is it possible to change it so that on a checkbox click the chart changes type in addition to the data, so for example from MSColumn3D.swf to MSLine.swf?  I want to be able to offer to my users a table of data and then radio buttons so they can select which data they want to see charted (in a single charting area) but different data would require a different chart.  Can I do this using only JS or would this require AJAX?

  <SCRIPT LANGUAGE="JavaScript">
  //In this example, we'll show you how to plot and update charts on the
  //client side. Here, we first store our data (to be plotted) in client side
  //JavaScript arrays. This data is hard-coded in this example. However,
  //in your applications, you can build this JavaScript arrays with live
  //data using server side scripting languages. Or, you can make AJAX calls
  //to get this data live.

  //We store all our data in an array data. It contains data for three Products
  //for 3 quarters. The first column of each array contains the product Name.
  //Thereafter 4 columns contain data for 4 quarters.
  var data = new Array();
  //Data for each product
  data[0] = new Array("Product A",659400,465400,764500,650500);
  data[1] = new Array("Product B",546300,436500,546500,332500);

yes, you can do this easily writing some extra lines of Javascript codes  and this wont need AJAX. You need to use javascript to define a new FusionCharts with new SWF name and set the dataXML/dataURL and render it to the same div containing the earlier chart.
