Fit Contributor

Hi,

just a question to the FitContributor: If I calculate the average values of an high-intensity period of an interval and write those values to the Fit file, does Garmin connect web make those values somehow visible or is it just a value in the Fit file?

There's a post here someplace about strings and the default length being 1. I('ll see if I can find it. Here it is: https://forums.garmin.com/showthread.php?359132-FitContributor-DATA_TYPE_STRING…

Hi IMGrant,

I already thought about this, but there is one reason I don't want to do this: performance. It's a really complex calculation I have to do. IMO it makes no sense from a datafield perspective…

Hi Travis,

I checked the graph in monkeygraph. In monkeygraph the graph is blue, as intended. In chrome the graph is depicted in black, in Edge browser the graph is invisible (but if you hover with the mouse over it you can see the recorded data at the cursor) and in Garmin Connect Mobile the graph is red.

I used this data type (float) since (as mentioned in this thread on post #28) I never got UINT8 running at all.

Edit: I just reviewed the source code of the Moxyfield and don't understand the "precision" in the resources file. The api says:
precision Decimal point precision for numeric data 0 for integer, 1 for one decimal point, 2 for two decimal points. Without this attribute the default is no rounding

Nevertheless, the Moxyfield states following in the resources file:

<fitField id="0"

        displayInChart="true"

        sortOrder="0"

        precision="2"

        chartTitle="@Strings.hemoglobin_concentration_label"

        dataLabel="@Strings.hemoglobin_concentration_label"

        unitLabel="@Strings.hemoglobin_concentration_units"

        fillColor="#FF0000" />

But in the code I can review:

const CURR_HEMO_CONC_FIELD_ID = 0;



        mCurrentHCField = dataField.createField("currHemoConc", CURR_HEMO_CONC_FIELD_ID, Fit.DATA_TYPE_UINT16, { :nativeNum=>54, :mesgType=>Fit.MESG_TYPE_RECORD, :units=>"g/dl" });

To be honest: for a UINT16 I would expect a "precision" of 0. Can someone clear things up?

This error is driving me crazy on all examples here, Do i have to name the fit contributions.xml different Â what im doing wrong

BUILD: ERROR: Fit contribution id=0's 'chartTitle' references non existent string ID

thanks

Perhaps you can share your fitcontributions.xml file? from the looks of it, seems like possible you didn't have a string defined for it?

See below for the "strings" and the FitContributions. The Fitcontributions is using the names it gets from "strings" (@strings)

    <strings>
        <string id="namaste_label">Namastes</string>
        <string id="namaste_graph_label">Namastes</string>
        <string id="namaste_units">N(s)</string>
    </strings>
    <fitContributions>
        <fitField id="0" displayInChart="true" sortOrder = "0" precision="2"
        chartTitle="@Strings.namaste_graph_label" dataLabel="@Strings.namaste_label"
        unitLabel="@Strings.namaste_units" fillColor="#FF0000" />
    </fitContributions>
