The measurement data is visualized using diagram widgets. This chapter introduces you to the common chart types and functions. More information about widgets can be found in the Widgets Widgets chapter.
¶ Chart Types
The Charts diagram widget package contains various diagrams that are available for displaying your measured values. A distinction is made between diagrams for time series and latest values.

¶ Point Query
Hover your cursor over the chart to see the point values of the readings.
¶ Free Choice of Temporal Resolution
You determine the temporal resolution of your diagram via the time window settings of the dashboard time window or the widget time window. Select the appropriate settings option in the widget settings.
You have the choice between real-time or historical resolution with freely selectable limits and grouping intervals.
In addition, the diagrams' zoom function allows you to take a closer look at specific sections of the diagram. The zoom area is set by clicking and dragging the cursor on the chart.
