Zendesk API usage export

Hello,

When looking at Zendesk API usage (APIs -> Zendesk API -> Activity), I see an average rate usually around the mid teens. When I look at the graph though, it seems like the spikes are in the 200-250 range. I do have the High Volume API because we were expecting some significant API usage, but that hasn't materialized. 

I would like the ability to export the hourly rate of API usage over as much time as possible; 2 weeks at least, 90 days would be ideal. 

Thanks.
