The Chart Menu

State Chart is a software post-processing feature that provides the

ability to build x-y charts of label activity using state data. The Chart

menu builds a graphical representation of the system under test. The Y

axis always represents data values for a specified label. You can select

whether the X axis represents states (rows in the state listing) or the

data values for another label.

When the X-axis is set to State, X and O markers are available which

display the current sample relative to the trace point and the

corresponding Y-axis data value. Marker placement is synchronized

with the normal state listing.

An accumulate mode is available that allows the chart display to build

up over several runs.

You can generate x-y charts of Label vs. Label or Label vs. State.

Label vs. Label charts

When labels are assigned to both axes, the chart shows how the data

acquired under one label varies relative to the other for a particular

measurement. Label values are always plotted in ascending order from

the bottom to the top of the chart and in ascending order from left to

right across the chart. Plotting a label against itself will result in a

diagonal line from the lower left to upper right corner. All markers are

disabled when plotting this kind of chart.

Label vs. State charts

Label versus State is a plot of data values acquired under a label versus

the memory location of the same data. The label value is plotted

against successive memory location numbers.
