[hhgs]

trafficstars

Use same track header size for all tracks to align all data plot with respect to the depth axis (ref. StimPlan model plots)

Snapshot for multiple horizontal plots

Things to improve

• align start of MD to make sure the depth axis is aligned between tracks
• make it possible to avoid unused plot area between plot (disable title, show only one depth axis, ....)-
