In this type of chart, only the discrete values of the variables are displayed. You can display multiple series of data for comparison. The heights of the bars represent the values of the series and they are animated in sync with the simulation.

Chart Axes

The axes of the chart are displayed differently depending on the units of the variables that are being plotted.

Units Variables Axes
Same One or more Displays one variable axis with units on the left side

Different Two Displays one principal axis on the left side for the solid curve and one secondary axis on the right for the dashed curve

More than two Displays one axis with no units
