Basic Visualization Widgets Sample Clauses

Basic Visualization Widgets. Visualization of sensors readings is achieved through the use of sensor statistics widget. The widget makes use the Highcharts library (▇▇▇▇://▇▇▇.▇▇▇▇▇▇▇▇▇▇.▇▇▇). Generally speaking, we consider two types of widgets, one for visualizing real‐time information (i.e., one single value) and one visualizing historical information (i.e., a time series). In order to visualize the real‐time value of a given sensor, a Gauge chart has been selected. To visualize the historical timeline of sensor measurements, a line chart has been selected. In the following we consider, for each of them, how they can be generated using the two approaches outlined in the previous section. 8.4.1 Real-time sensor reading visualization widget
