 +The statistics details page gives a static preview of the elevation and speed profile. In order to get a fullscreen and dynamic version, click on ''"**Fullscreen**"'' {{:icon_01.png?nolink}}. On the fullsccreen page, you can: 
 +  * Click anywhere on the profile {{:icon_02.png?nolink}} to get the exact values at this location; 
 +  * Click on the ''"**Change X axis**"'' {{:icon_03.png?nolink}} icon to change the abscissa to ''"**Length**"'' or ''"**Time**"''; 
 +  * Click on one of the ''"**Change Y axis**"'' {{:icon_04.png?nolink}} icon to change one of the ordinates. The list of available fields {{:icon_05.png?nolink}} depends on the data included in the track file.

 +===== How to export statistics and graphics data? ===== 
 +\\ 
 +Before computing statistics and displaying graphics of a track, the application will process its raw data (usually recorded using the GPS) based on the chosen settings to remove recording inaccuracies and discrepancies. You can export the processed data in a .CSV file: 
 +  * In the details view of a track, click on the action menu {{:icon_01.png?nolink}}; 
 +  * Select ''"**Export as...**"'' {{:icon_02.png?nolink}}; 
 +  * Choose ''"**CSV file / Profile (Data file)**"'' {{:icon_03.png?nolink}}. 
 + 
 +{{:icon_help.png?nolink}} After the export, you can easily share/upload the generated file using the ''"**Share**"'' button. 
 + 
 +{{ :en:help:v2:landmarks:statistics-4.jpg?nolink }} 
 + 
 +The following fields are exported: 
 +  * ''"**Longitude**"'' and ''"**Latitude**"'', the coordinates of the location buckets in the WGS84 (GPS) datum. A location bucket is a set of one or more locations from the original track, grouped together for algorithmic reasons; 
 +  * ''"**Distance**"'', the cumulative distance from the start point of the buckets, in meter (m); 
 +  * ''"**Time**"'', the cumulative time from the start date of the buckets, in second (s); 
 +  * ''"**Elevation**"'', the mean elevation values computed for the buckets, based on the GPS altitude values, in meter (m), over the EGM96 (Geoid) ellipsoid; 
 +  * ''"**Speed**"'', the mean speed values computed for the buckets, in meters per second (m/s); 
 +  * ''"**Slope**"'', the mean slope values computed for the buckets, in percent (%); 
 +  * ''"**Sea-level pressure**"'', the calibrated, sea-level equivalent mean pressure values computed for the buckets, in hectopascal (hpa); 
 +  * ''"**Pressure**"'', the un-calibrated, raw mean pressure values computed for the buckets, in hectopascal (hpa); 
 +  * ''"**Barometric elevation**"'', the mean elevation values computed for the buckets, based on the pressure values, in meters (m), over the EGM96 (Geoid) ellipsoid; 
 +  * ''"**Accuracy**"'', the mean accuracy (with a 68% confidence) values computed for the buckets, in meter (m); 
 +  * ''"**Elevation (diff.)**"'', the mean difference values between the GPS elevations and the barometric elevations for the buckets, in meter (m);

 The gain is an important value that helps to appreciate the overall profile of a track. A small gain means that the track is mostly flat, a high gain means you'll have to climb a lot. The gain is an important value that helps to appreciate the overall profile of a track.
