I attach three images;
The first is a screenshot of the HRM graph in connect of a Swimming with HRM activity;
The second is the same graph rendered in the Garmin Connect App;
Normally other charts look the same but in case it looks like they are reducing the data point too much.
Here is a another HRM graph from my droid from a run activity (it looks nice);
I look to look at the graph, but the swim graph is unusable. Please Garmin, can you fix it (Also looks rubbish on my Nexus 7" tablet)
