Heart Rate x-axis not consistent

[tituscmd]

The x-axis for the heart rate chart is inconsistent. Ideally, the intervals between hours or minutes should be equal. Right now, the spacing is all over the place, with some sections showing 2 readings in 3cm space and others packing 5 readings into just 1cm of space.

For clarification:

In the image I added, the portion of the chart marked by yellow lines appears to represent about half of the total data (last 3 hours). This suggests it should represent about 1.5 hours of data. However, it actually only displays data from 20 seconds of continuous measurement.
