Chart DataSource reverting to original

[Jonathan]

I have code that updates the datasource of a chart and it works fine.  I also have code that changes the chart from a column to bar to line.  That also works, but any time the .refresh() method is called on the chart, it reverts the datasource to the original data source.

Was wondering if this is a bug, or a feature change.

Testing steps:
Change the "Select parking area filter" from 0 to 4.  Notice the chart refreshes with values of 5 (n+1).
Change the "Chart type" from column to bar.  Notice the data source reverts back to original.

The fiddles below are identical except for the kendo.all.min.js included.

Hi Jon,

Thank you for pointing our attention to this issue. Indeed, the problem occurs because in the current version of Kendo UI the Chart internally uses DataSource read() method for refresh. Such approach will undergo changes for our next official release, but I am afraid currently I can not offer a suitable workaround for your scenario. Please excuse us for the inconvenience.
