Apple Watch Activity Data

I hope someone can tell me that what I am looking for is there but I am just not looking in the right place. I used a Garmin smartwatch for about 2 years before switching to the Apple series 4. I have no regrets about this as the Apple is, in my view, a superior watch except in one regard - summary data on my iPhone. If I look at the history data on my phone, all I can find is a month of coloured targets which are to a greater or lesser extent completed on a day by day basis. What I would really like to see is what Garmin did a pretty good job of is to summarise data over months and a year. For example, I would like to see how my step count averages over 3, 6 and 12 months. Or when I have been working hard, I would like to see a high quality graph on my phone showing heart rate hour by hour. These summary stats are really useful for tracking progress. I think the Apple Watch is great but the history stats let it down.
