Hello everyone,
i have the follwing situation:

I have an Ext.Panel with an Ext.chart.PieChart within.
For some information reasons i have to change the tooltip of each slice.

Here is my code (abbreviated)
Code:
var chart = new Ext.chart.PieChart(
  {
    store: config.chartStore,
    xtype: 'piechart',
    dataField: 'total',
    categoryField: 'project'
  }
);
chart.setTipRenderer(
    function() {
      console.log("tiprender")
    }
);
This is what whate Chrome tells me
Code:
ext-all-debug-w-comments.js:55237Uncaught TypeError: Object #<HTMLObjectElement> has no method 'setDataTipFunction'



I looked into the src of the Chart.js and found the following line to cause the error:
Code:
chart.swf.setDataTipFunction(chart.tipFnName);
(At least i think so).


How to fix this?


Kind regards,
Timetrick
