This script takes a delimited string of level values (up to 12) and plots them on the chart as per parameters. Alerts can be set up for crossing, etc, using the Alerts panel as per usual.
Very handy if you have a spreadsheet or list of values to plot.
For example, say your spreadsheet has a list of these 12 levels to plot: 3800 3811 3822 3837 3851 3862 3877 3887 3902 3913 3928
The values could be copied to notepad / text editor, and the line breaks replaced with a delimiter, such as the ';' character (note: no trailing delimiter), to produce a delimited string: 3800;3811;3822;3837;3851;3862;3877;3887;3902;3913;3928
And then simply copy / paste this delimited string into the "Levels Delimited String" parameter.
