Tracks without moving points break some functions

[kschweiger]

pythontrack = PyTrack(
            points=[(1, 1), (1.0001, 1.0001), (1.0002, 1.0002), (1.0003, 1.0003)],
            elevations=[100, 105, 110, 110],
            times=[
                now,
                now + timedelta(minutes=1),
                now + timedelta(minutes=2),
                now + timedelta(minutes=3),
            ],
            extensions={
                "heart_rate": [120, 130, 140, 140],
                "power": [150, 160, 170, 170],
            },
        )

gives

   latitude  longitude  elevation speed   distance  time  cum_time  cum_time_moving  cum_distance  cum_distance_moving  cum_distance_stopped  moving  heart_rate  power  segment
0    1.0001     1.0001        105  None  16.516744  60.0      60.0                0     16.516744                    0             16.516744   False       130.0  160.0        0

fails with

  File "/../../../site-packages/geo_track_analyzer/track.py", line 228, in get_track_overview
    track_max_speed = track_data.speed[track_data.in_speed_percentile].max()

The column in_speed_percentile is only set if there are moving points. If you reduce the time delta to 30 seconds it works with:

   latitude  longitude  elevation     speed   distance  time  cum_time  cum_time_moving  cum_distance  cum_distance_moving  cum_distance_stopped  moving  power  heart_rate  segment  in_speed_percentile
0    1.0001     1.0001        105  0.550558  16.516744  30.0      30.0             30.0     16.516744            16.516744                     0    True  160.0       130.0        0                False
1    1.0002     1.0002        110  0.550558  16.516744  30.0      60.0             60.0     33.033488            33.033488                     0    True  170.0       140.0        0                 True
2    1.0003     1.0003        110  0.524725  15.741754  30.0      90.0             90.0     48.775241            48.775241                     0    True  170.0       140.0        0                 True

The column should just be there in any case
