Thank you.  The problem is that when you stack it adds the values together and that is not what we need.  We need to related values to be closer together.  We have put in two tickets to your team and both said that what we are looking for is not possible via Kendo and they recommended that we put in a new request for new functionality. (Support ID:852517 -- Bar chart spacing between series && Support ID:843391 -- Kendo UI Chart Zoom with stacked bars). In the tickets I provide jsbin examples.  Let me know if these are clear enough.

We tried that option, but it didn't zoom correctly.  See, our data is stacked with the aggregate being no more than 100%.  The bottom bar is usually around 98% while the one stacked on top of it is about 1%.  Since the data is always all around the 100% mark, we would like to zoom in to see the 95-100% range.  However, when we use the inherent zoom, it gets rid of the 1% bar because it is less than the 95% we zoomed to.

That's when we tried grouping within the category series of the bar chart (so that we could move a 99% bar behind a 98% bar and get the same effect as the stacked bars but with appropriate zoom features).  However, we cannot group "like" bars within a category series, which is what we would like Kendo to implement.

Thanks,
