I faced the need to visualize the Azure EA usage data for multiple subscriptions. You can download the usage data for your subscriptions from https://ea.windowsazure.com but the resulting excel file is a flat list of usage data on daily base. Within the data you can find the “ResourceQtyConsumed” and the “ResourceRate” from which the cost can be calculated.
This Screenshot shows the pivot table from the attached excel file in which you can easily import your usage data and visualize the usage data per subscription.
