Too many values

Hi,

I am building simple column chart which represents sold items by stores. We have 171 stores. I supposed to get 171 columns to see sales of every single store. After creation there is yellow triangle with exclamation mark in the upper left corner of the chart. After clicking on it I see this Message:

Why do I get this error? I mean 171 is quite normaln as you have slider at the bottom of the chart. Yes I can filter stores by some category. But on the top level, ct wants to see all the stores as you can see in excel pivot table not saying you can do it in any other visualization tool such as Datawatch, Qlikview...

PowerBI should handle it.

Is there any limitation on the columns, chart can presents?
