Examples
A single-scale Y-axis chart uses one numeric scale for all tags shown on the chart, regardless of the units of measure used for each tag. This example shows autoscaling enabled.
A stacked Y-axis chart is a collection of single-tag charts. It uses an individual Y-axis scale for each tag and stacks each of the single-tag charts vertically on the screen.
A multi-scale Y axis chart also uses individual Y-axis scales for each tag, but includes all tags on the same chart. Since the Y axis represents multiple scales, the upper value for each tag is displayed above of the chart.
