So, when I do this, I don’t get the same results. Can you share a few details with me, please?
- Which browser and operating system? Brave browser with Windows 10 and Ubuntu 16.04
- When you turn on the javascript console, are there any errors? Haven’t checked
- Are you defaulted to metric or imperial units? Imperial
- What is your default activity type? Treadmill
- Does this also happen when changing the activity type on an existing activity? (it doesn’t for me)
Starts on Treadmill and miles; when I switch to swimming it automatically switches to Yards; I enter the number 1; then if I switch the unit to Meters it changes to 1609.34, but if I switch to Miles it stays 1
Thanks, we’re through the easy stuff and into the tricky. 
Cheers,
-Eric
I just noted today, also, that there is an anomoly on the weight chart. I started recording my data this year, but I recorded no information between the recorded dates of 3/9 and 3/18. (This is correctly noted on the recorded data.) On the graph, however, the dates from 3/18-3/28 are on the left of the graph, followed by the data starting from 1/1 and going steadily to 3/9, followed by a jump in date to 3/29, and then continuation from there. Note that, visually, the distance from 3/8 to 3/9 is the same as that from 3/9 to 3/29. Note, also, that the dates for the legend on the bottom (excluding the ‘2021’ common for all) are, in sequence,
3/18, 1/6, 1/22, 2/14, 3/2, 4/6, 4/22, 5/6, 5/20, 6/3
All separations are 16 days except 3/18-1/6 and 3/2-4/6 (35 days, not even a multiple of 16?!)
Another possible indicator of where the bug may be is that, in the main part of the graph where the dates run properly, the separation of the dots for the measurements is the same, even if the consecutive weighings are separated by 1 or 2 days. (I.e., if weight was recorded 5/3, 5/4, and 5/6 (but not 5/5) the dots for 5/3, 5/4, and 5/6 would all be separated by the same distance.)
This is on Brave using Ubuntu 16.04.
I’ll see what it’s like for other browsers if you like; I just have a lot of crap open right now and if I open another browser I’ll have to spend an eon waiting for swapping.
