TackTracker has the ability to import and display custom statistics - fully integrated with the built
in statistics. Custom statistics are integrated into TackTracker's charts, tables and reports.
Some examples of custom statistics are:
· Speed through the water
· Angle of heel
· Mainsheet position
· Competitor heartrate
· Wind speed
Any timestamped floating point numeric data is suitable, from any data source. The data may be
imported into TackTracker in CSV, GPX or NMEA formats. TackTracker can merge and integrate
your custom stats data with matching tracks in your library. These tracks can be shared with
others, and the custom statistics will show correctly in any other TackTracker player - including
the web player.
Each custom statistic has an associated definition, which names the statistic, describes how it is
to be displayed, and how to recognise it in the input files. TackTracker has a stats definition
syntax for each of the above file formats. You can define a custom stat in TackTracker, then
create a sample file to demonstrate the required format.
The custom statistics dialog is found on the "Custom Stats" tab of the Settings dialog.
The dialog looks like this:
After you have defined a custom stat using this dialog, you can:
· Create a sample CSV, GPX or NMEA file to show you how to define the input data.
· Import data containing the custom stat from one of these file formats and merge it with
existing track data.
Custom stat definitions are not saved within TackTracker. The definitions reside with the data,
and TackTracker learns about the stats as and when the data is loaded.
Explanation of fields in the dialog:
Field
Description
Key
Unique id for the stat. Used as a column header in CSV files.
Name
Display name shown within TackTracker in table headings, charts
etc.
Tag Name
Name of the GPX tag containing the stat, or the NMEA sentence.
E.g if the Tag name was ex1, the NMEA sentence would begin $ex1
Tag Index
An NMEA sentence may contain multiple parameters, separated by
a comma. This is the zero based index identifying the parameter
that contains your stat. You may combine multiple custom stats into
the one NMEA sentence.
Date Index, Time Index
Custom stats must be timestamped. In NMEA files, this may be
achieved either by including standard $GPRMC or $GPGGA
sentences alongside your custom sentence, or including date and
time parameters in your custom sentence. If you do the latter, you
need to specify which parameters are date and time.
