stacked bar with varying data

[Paul]

There's probably a simple way to do this but I'm darned if I can figure out what.

I want to build a stacked bar chart roughly similar to the example at http://demos.telerik.com/kendo-ui/bar-charts/stacked-bar. The chart will show the top-N user activity per day. So for today, let's say that Alice did 100 units of work, Bob did 75, and Carole did 82. I want the stack to reflect that. Yesterday Mike did 75, Alice did 84, and Eve did 84.

I'm having a hard time figuring out how to get the stacks to reflect my data. Basically what I want is a stack for each day, with each "slice" of the stack showing activity. All of the Kendo chart types seem to assume that you'll have the same stacks every day, e.g. that every day I want to show what Alice, Bob, and Carole did. What I actually want is to show a stack per day where the components of the stack show (and the tooltip reflects) whatever the most active users for that day did. The same users may be most-active on multiple days but they may not.

Is there a straightforward way to do this with the built-in chart types?

Hi Paul,

For this scenario I would suggest to group the chart dataSource:

http://docs.telerik.com/kendo-ui/controls/charts/data-binding#bind-to-grouped-data

Please keep in mind that when there is a different number of points in each of the groups you should specify series.categoryField instead of categoryAxis.field: 

http://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart#configuration-series.categoryField

Take a look at this example which demonstrates the suggested approach in action:
