Heatmap: Draw lines between data points rather than big dots

Browse source 
By drawing oversize dots for each data point, dots were overlapping such that
the change in tissue presssure wasn't displayed at the right time - typically
out by 1-2 minutes, depending on dive duration.

Drawing a line between discrete points, the data points don't overlap and
change in tissue pressure is displayed at the right time.
