Visualizing the intensity of data values (Heatmap)

The Heatmap widget visualizes the history of the intensity of data values. You can, for example, display the energy consumption (red = high energy consumption; green = low energy consumption), machine states or production quantities in a specific period.

Procedure

To define widget-specific display options, follow these steps:

  1. Create a new widget or edit the existing one.

  2. In step 3 "Details", you define

  3. The KPI calculation period

  4. Whether the data is displayed in the day view or the week view.
  5. The color in which the different intensities are to be displayed. If required, specify the values for minimum and maximum of the color scaling.

  6. If you do not define fixed values, the lowest and the highest measured value is used for the color scale. In case of extreme peaks, the Heatmap may return a distorted picture.

Result

The Heatmap visualizes the data values according to the assigned color scale.
