The Graphing Tab

Last Updated: May 09, 2017 04:26PM CDT

The Graphing Tab is a good way to quickly view the activity within your dataset. It includes both the Daily Graphs and Inclinometer pages. This tab can only view single .AGD files at a time, and they can be loaded clicking the "Select Dataset" button.

Daily Graphs



The Daily Graphs page allows you to view your data on a day-by-day basis, and is a great way to get a general overview of a subject's activity. Here is a brief explanation of what the Mode Options on the right hand side do:

Axis 1 - Shows Activity Counts on the Y axis.
Axis 2 - Shows Activity Counts on the X axis.
Axis 3 - Shows Activity Counts on the Z axis. 
VM - Vector Magnitude is the Square Root of X² + Y² + Z². If you know you're going to be using Vector Magnitude based algorithms when you analyze your data, use this option.

If the options were enabled when your .AGD file was created, you can also view Steps, Heart Rate, Lux (light), and Inclinometer results using the selection bubbles. Take note that any of the colored squares to the right of these options can be selected and a new color can be chosen if desired. 

Show Cut Point Lines - This will toggle the Cut Point lines on and off. By default this option is on, to help give a better indicator of the subject's intensity. 

Equal Activity Scales - Having this option selected will equalize the cut point lines on each row. The Activity Count "ceiling" for each row can be modified by changing the number displayed. This is just a visual option, and has no effect on the data itself.

No Mode Selected - This is going to be grayed out by default; this option applies to the secondary graphing data only (Steps, Heart Rate, Lux, Inclinometer). When any of those options are selected, this will be unlocked, and functions identically to the "Equal Activity Scales" option. 

These Graphs can also be exported to PDF format. Clicking "Export to PDF" will bring up a new window, which will allow you to select which days to export, whether or not to keep any zooming done on the graph, and whether or not to show the Cut Point lines. 





Inclinometer



The inclinometer function applies algorithms to the accelerometer data to determine the position of the subject. Each row has an hour of data, and each colored column represents one minute of data. On the right hand side, you can change the color of each position if desired, and select different days within the dataset to analyze. As with the Daily Graphs page, you can also export this information into PDF format. Please be aware that the inclinometer function will only be accurate with waist or thigh worn data, because that is what the algorithms were made to look at.
