Hi,

The documenation states that I should be able to use 'notifySetItem' to update the chart whenver my data source is updated. However, I'm getting an error stating that 'notifySetItem' is not a method on igDoughnutChart.

I've done some experimentation with the other methods (updateSeries, addSeries, and removeSeries) and I'm seeing some inconsistent behavior that I hope someone can help sort out.

After updating an item in my collection, I'm able to use updateSeries to refresh the chart. However, newly inserted data doesn't show up. I managed to get inserted data to display in the chart by calling removeSeries followed by addSeries. It works, but is not ideal.

Here are the examples on jsFiddle:

Example 1 binds an array and has a button to update and add an new element to the array. It uses 'udpateSeries'. Notice how the newly added item doesn't show up.

Example 2 does the same thing as Example 1 but calls 'removeSeries' and 'addSeries'. Notice how the newly added item shows up.

Thanks in advance for your help,
