Feature request: Add data export option for Flexibility Index time plot

[rosamaryo]

Currently, the output options of Flexibility index are: time plot, common plot, summary table (1 row per org attribute) or full data. What I think is missing and would be really helpful is output of the data used in the time trend chart (1 row per week with the average FI) to be able to recreate that chart in ppt and keep adding weeks of data - customer will do this to track this on a monthly basis as a KPI.

Describe the solution you'd like

return = "table_time"

Describe alternatives you've considered
The solution now is to just save the full data (return = "data"), and do a simple summary:

group_by(Date) %>%
summarise(FlexibilityIndex = mean(FlexibilityIndex)) %>%

which maybe is the right approach if we don't want to start creating very specific data outputs. If that's the case, I suggest to just save this approach as an FAQ. Thank you!

Thanks @rosamaryo for this issue. I lean towards adding this as an extra example in the section under https://microsoft.github.io/wpa/reference/flex_index.html, because it is only a one-line code to run. Maybe good to get some thoughts from current users to see what is preferred, because keeping the return options simple would also be great

I will add the following example to the documentation, instead of adding another return option:

To return the underlying data for the time trend view, you may run the following code: 

em_data %>%
  flex_index(return = "data")  %>%
 group_by(Date) %>%
 summarise(FlexibilityIndex = mean(FlexibilityIndex))
