Hi,

 

It is not possible to re-render a chart without making the legend of a dataset invisible, directly.

 

But as a workaround, you may update the data of a chart at runtime. You may have configuration options for a chart, then do a postback with the configured options, and then update the chart with the newer data from the server.

 

This can be done by obtaining the chart reference by passing the DOM Id of the chart and updating the chart with new XML/JSON data.

Ref.

 //Get reference to chart object using Dom ID
  var chartObj = FusionCharts(domId);
   
//Update it's XML 
     chartObj.setXMLData( "newData");

 

Now, in the new XML/JSON Data, you may set the attribute "visible" of the dataset element to 0, to mark a dataset element invisible  by making the legend of the dataset being visible.

 

Ref. 
<dataset ... visible='0' >

When you do this, the dataset is not visible on the chart but its legend is visible and the corresponding dataset appears when you click on it.

 

Please find an attached sample using the above approach. Also, please note that this works only with JavaScript charts.

 

Hope this helps.
