Column mock-up

This column mock-up plot is a simple plot of the data to allow visual comparaison with the output from TimeScale Creator. For interval tables the defining events are also shown

The data plotted here is the Major Cambrian markers column from the trilobites dataset for the interval. For intervals tables the events re also shown 0 - 700 Ma
