History mainpage

Local TOC

General (toc)

Purpose: junction for access to historic tracks.

The History mainpage gives access to ended track - i.e tracks with state RECORDED (and UPLOADED - covered later). All outputs shown are based on a time range given by setting The datepickers.

After tapping   Use date+clock   and   Set time range to whole history  , the History mainpage could display as:

Using date+clock mode

If you go to this page before anything was tracked, a message pops up:

Using date mode

The datepickers (toc)

Occupies the middle part of the page body and are constituted by two wheels, that specifies a time range, i.e. an interval ranging from Time from to Time till.

All track data are saved with a timestamp which includes seconds. The datepickers don't include seconds - but behind the scene, Time from has a zero seconds suffix, and Time till a 59 seconds suffix.

A track starts with departure time (short: Dep), i.e. the time tracking started. It ends at arrival time (short: Arr), i.e. the time tracking was ended.

The time range of a set of tracks spans from departure time of the oldest track till arrival time of the newest (ended) track. It cannot expand beyond that.

If you try to drag a wheel beyond these limits, it will bounce back to its lower or upper limit.

On the other hand, the time range of the datepickers can be narrowed down to just one minute - whether that minute is found in any track or not.

Example A: time range is expanded full to comprise whole history:

   ....Track1....   ....Track2....    ....Track3....

Example B: time range only covers part of the history:

   ....Track1....   ....Track2....    ....Track3....

The   Set time range to whole history   button is disabled in example A (after having been used), and is enabled in example B.

To avoid a Time from > Time till situation, it you drag one wheel beyond the value of the other, the latter will follow.

In the screen above, the datepickers operate in date+clock mode, which is needed if you need to specify a very exact or narrow time range.

By tapping   Use date only  , mode is changed to date only, which is the most comfortable way to look at whole days, and also reveals the year:

Using date only mode

The   Use date+clock   and   Use date only   buttons are mutually exclusive - tapping the one that is enabled will disable itself and enable the other.

Finally, the   Copy down   and   Copy up   buttons attached to the datepickers can be helpful when defining narrow time ranges (in date+clock mode) or same day (in date only mode). Both are disabled when the wheels are set equal.

When you have set a time range, the   Show   buttons at the top are ready to give different outputs, covering the same period. You can show one (sub)page, return to history, and then show another (sub)page using the same or another time range.

Buttons showing track sections (toc)

The buttons:

open subpages that operate on track sections, i.e. straight lines connecting adjacent plots. Together, the lines constitute chronologically consecutive part(s) of one or more tracks.

For something to be drawn on the Map or shown in the Barchart, at least one track section must live within the given time range, meaning at least two plots must have timestamp falling within the time range.

For something to be listed in the Report, just one plot must have timestamp falling within the time range.

Plots may or may not have events attached.

Example C: time range comprises parts of two tracks:

   ....Track1....   ....Track2....    ....Track3....

** Result: parts of both Track2 and Track3 are included.

Example D: time range comprises one whole track and part of another:

   ....Track1....   ....Track2....    ....Track3....

** Result: whole Track2 and parts of Track3 are included.

Anyway, if nothing can be shown, a popup appears:


or - if Barchart cannot process a too narrow time range - this may popup:


Buttons showing whole tracks (toc)

The buttons:

open subpages that operate on whole tracks as explained below.

TIP: tap   Set time range to whole history   and   Tracklist-   to make your newest (ended) track appear first in the Tracklist.

Example E: Time range comprises one whole track:

   ....Track1....   ....Track2....    ....Track3....

** Result: Track2 is included in the Tracklist.

Example F: Time range does not comprise any whole track:

   ....Track1....   ....Track2....    ....Track3....

** Result: nothing is included.

Example G: Time range comprises two whole tracks, but not only whole tracks:

   ....Track1....   ....Track2....    ....Track3....

** Result: Track2 and Track3 are included.

If nothing can be included in a Tracklist, a message appears after tapping one of the show buttons:


No entitlement (toc)

Unless you have Full functionality, and you tap any of the six buttons at the top of this page after having set the datepickers to span more than TEN days, you will be rejected with a message:

Message when no entitlement
