When the data set is changed and the chart is redrawn there should be an option to move from the current values to the new values. Like it already exists on the gauge charts. But what about a line chart with ever changing values?
Do you mean something like this: http://demos.kendoui.com/dataviz/api/benchmark.html Note that you can use the chart's refresh method (http://docs.kendoui.com/api/dataviz/chart#methods-redraw) for this purpose, and invoke it once its data source data changes.
