Can I track a goal for a specific community?
Yes! Just click on the goal and use the community filter to select the community you need and then click the pin icon in the top right.
How do I smooth out the chart?
If you can use the granularity filter and select a larger time period (e.g. week instead of day, or month instead of week), you'll see fewer of the peaks/troughs (often caused by weekends).
How do I stop tracking a goal?
Just click the pin again and you'll see it change from black back to grey.
What does the trend relate to?
This shows a comparison to the previous period - and is dependent on the date filter you've selected (use the calendar icon in the top right to adjust). If you have selected the last week (the default option) then the trend will compare the past 7 days to the 7 days prior to that; similarly if you've selected the last month then it'll look at the past month and compare to the month before that.
