Name: Power Chart
Rating: 4 (4 reviews)
Author: bjarnib

Displays a chart showing power for the last few minutes colored by power zones. 
The data field supports the following settings through Garmin Express or the Garmin Mobile App:

* Check box allowing display of horizontal grid lines for the power zones.

* Averaging interval for the power value (1s/3s/10s/30s)

* The maximum value of the power scale display

* The Functional Threshold Power (FTP) for the user

* Percentages of FTP for the user's power zones (z1-z7)

This field can be combined with other data fields on multi-field training pages.   Note that to make the display more readable on a smaller screen, the field does not display the numerical readout of the current power.    To get the numerical readout, place the field with another separate Power field(s) on a multi field screen.  

Also note that you need to set your FTP and zones in the settings for the app as the app can not access the FTP/zone data that you may have set on your device. This is currently a limitation in the Garmin Connect IQ framework.

An ANT+ power meter must be paired with the device to provide the power data.
