I would like to programatically create some horizontal min and max grid lines on a chart to bracket some data to show out of tolerance. Anyone know how?
Add 2 extra plots to the chart - one will be the min line and one the max. To do this, bundle the three data values and wire the resulting cluster into the chart terminal.
You can also add cursors with only the horizontal line showing and set their values. If you want to use min max values which are not horizontal but have a slope or vary with time, adding 2 plots (functions of max/min) are the way to go.
