Could you elaborate? There is times report:
http://demo.piwik.org/index.php?module=CoreHome&action=index&idSite=7&period=day&date=yesterday#/module=VisitTime&action=index&idSite=7&period=day&date=yesterday

We need to see the level of detail of both the day and the hour.

For example:
Day|Hour|Visits
2015-03-23|00:00:00|86
2015-03-23|01:00:00|27

Did you take a look at the link I pasted in the previous comment?

Yes, I did. The link shows an hourly bar chart. From that bar chart I can compare hours, but I can't tell which days. We need to be able to show how the visits are changing from hour to hour for everyday, this will enable us to see trends and spikes or dips.

Thanks for the suggestion. The data is already available as @quba pointed out but you need to change the days in the calendar manually... This will become a bit easier when we implement the "selector" to view hours when a day period is selected in #955

+1 for having the option to view data without the normalization of visit times. I think it's a neat option to have it the way it is, but am 10x more interested in a report that does not account for different time zones.

FYI: The CustomReports plugin lets you view anything by hour and with next Matomo update you can even view quarterly reports, per weekday, per ....

for example visits per day per hour, visits per quarter, page views per hour, downloads per hour, downloads per weekday, downloads per ...

I appreciate the response.... but $200+/yr seems quite expensive for a small site to get one already present report in a rawer state. I appreciate that it does more... but not looking for any of those extra features yet.

Perhaps an opportunity for me to make a little plugin and contribute :).

Hi, the link from the second commed is broken now. Can you find new one? Or some dscription how I get to this view in my matomo?

@jitka the Custom Reports plugin can do that. In core itself we won't be adding this in the next few years simply because it would impact performance a lot (report generation would basically take 24 times longer), storage (24 times more storage for the reports), and would also make the UI more complicated. It would also take several months to implement.
