Create monthly charts

[egiafra]

Hi,
I want to create a charts that shows the results of a researchkit task for a whole month instead of a single week. I've already managed to modify the view of the charts, but I'm having some problems in figuring out how to fetch the results of the events of the whole month. I hope someone can help me.

Hello! Which version of CareKit are you using, and are you building out your view in SwiftUI or UIKit? If you're interested in trying out the 3.0 beta release, we've introduced some new SwiftUI APIs that will make it really easy to map event data to a chart -

struct MonthlyChartView: View {

    private static var query: OCKEventQuery {
        let monthInterval = Calendar.current.dateInterval(of: .month, for: Date())!
        let query = OCKEventQuery(dateInterval: monthInterval)
    }

    @CareStoreFetchRequest(query: Self.query)
    private var events

    var body: some View {
        buildChartView(using: events)
    }
}

Alongside that, you can also make use of the CareTaskProgress API to aggregate the progress for multiple events and display the resulting value in the chart.

Hi Gavi, I've started to review the 3.0 updates and look forward to testing. I also plan to graph a variety of outcome values, not limited to ResearchKit. My question is whether I could obtain the same result using @CareStoreFetchRequest with an OCKOutcomeQuery over a date range instead of an event query? What are pros and cons of querying events vs outcomes for this use case? If querying for events, I assume that I'd just need to map the events to a collection of outcome.values anyway. Thanks, Dave

Hey Dave apologies for the late response here.

You can also stream outcomes over a date range. The CareStoreFetchRequest can be initialized with each type of care store query:

@CareStoreFetchRequest(query: OCKOutcomeQuery(dateInterval: someInterval))
private var outcomes

The decision between querying for outcomes or events will depend on what you plan to do with the data. Querying for just outcomes is probably a little bit faster, but is missing some perhaps useful information (task, event start, event end, etc.). You also won't have access to the progress computation methods available on an event. Though, it might be useful for us to provide that progress method on the outcome level as well one day.

Does that help clear up the differences?
