Plot chart

Add a plot chart to a workspace to show trends over time among related attributes. Use the chart styling options that are available in the Properties editor to refine the appearance and to add options such as chart overlays.

A plot chart shows changes over a period of time by drawing a continuous line from one data point to the next, one data point for each data sampling and one line for each attribute selected. This type of chart is useful for showing trends over time and among related attributes.

Each time you open the workspace or edit its properties, the plot chart starts anew. The first set of data points is plotted, the next set is plotted after the refresh interval, and a line is drawn from each previous plot point to the current one. If historical data is being collected and a time span has been specified, the plot chart is populated with the historical data (unless data collection was started only recently and historical data has not been gathered yet for the period specified).

The redistribution and restarting of data collection can result in some gaps in the data if the collection interval is frequent, because collection is aligned with time boundaries. Time gaps in your data might affect your plotted points. In some cases lines might not be drawn to connect plotted points.

After adding the chart, use the styling options in the Properties editor to refine the appearance. If the Properties editor is not open, click Properties editor icon Edit properties in the view's title bar. The Font style iconStyle tab shows a thumbnail graphic of the chart with areas that you click to edit the corresponding options.
