Update datasource

[Ole Jørgen]

I am testing similar to the demo: http://demos.kendoui.com/dataviz/bar-charts/remote-data.html

How can I update the remote data (without refreshing the chart altogether). I want to get updated data from the server and have the bars change their values accordingly.

Hi Ole,

By design, when Kendo UI Chart is bound to a dataSource (like in most of the online demos) and such dataSource is changed the Chart widget will automatically refresh. For your convenience I prepared a simple jsBin example which demonstrates this in action.

I have modified your example to show what I want:

I would like the animation to be from current value to new value instead of always animating from 0. Is that possible?

Hi Ole,

I am afraid what you would like to achieve is not supported in Kendo UI Chart and there is not suitable workaround I can suggest. Please accept my apologies for the inconvenience caused.

So, with a local DataSource, how would I go about providing a completely new set of data once the DataSource has been activated and the Chart rendered? Do you reset the variable with a new datasource instance again, or set someDataSource.data(newData);?

Hello Robert,

In order to achieve this you can use the DataSource's data() method. For your convenience I updated the jsBin example from my first post to illustrate this approach in action.

Just wanted to share, after two hours struggle with Kendo MVC wrapper chart to refresh on a button press, with you sample js (read method) i got it working. Thanks a lot.
