Calendar Heatmap

Open

A calendar heatmap is a graphical representation that condenses time-based data into a compact visual display. It uses a calendar layout to map data values to individual dates, using color intensity to indicate the magnitude of the values. Each day in the calendar is assigned a color, with darker shades representing higher values and lighter shades representing lower values. It can be used to visualize the following data:

1. Manufacturing Downtime: Calendar heatmaps can be used to visualize equipment downtime over time. This helps identify recurring issues, plan maintenance, and optimize production schedules.

2. Production Output: Tracking daily or monthly production output helps identify peak periods and bottlenecks in the production process, aiding in capacity planning.

3. Energy Consumption: Calendar heatmaps can visualize daily energy consumption patterns for industries or households, aiding in energy conservation efforts.

4. Renewable Energy Production: Displaying solar panel output or wind turbine performance on a calendar heatmap helps analyze energy generation trends and optimize system maintenance.

Starting the Control

To start the control click on the “Assets” button in the upper left corner of the PI Vision display.

In the upper part select “weruCalendarHeatmap” by clicking on it.

Afterwards the desired attribute from the asset tree could be added to the display via drag and drop. The Calendar Heatmap control appears on the display and can be used.

Configuration

With a right click on the control it is possible to press "Configure". Thereby the configuration tile appears.

• Settings

  • Auto Limits: Sets minimum and maximum value dynamically depending on the data

  • Get limits from AF: Sets minimum and maximum value from the asset/attribute that was initially used for the control

  • Minimum: Configures the minimal value for the control

  • Maximum: Configures the maximal value for the control

  • Intervals: Specifies how many intervals the range between min. and max. is divided into

  • Use continuous scale: Does not divide the range into different intervals, but uses a continuous color range

  • Aggregation: The control uses all data points that are available in the selected time range. These are aggregated per day. The following data points are available:

    • Integral: Computes the definite integral over each day

    • Minimum: Considers only the minimum value per day

    • Maximum: Considers only the maximum value per day

    • Average: Computes the average value over each day

    • Standard Deviation: Computes the Standard Deviation for each day

  • Min Color: Sets the color for the lowest number

  • Max Color: Sets the color for the highest number

Removing the Control

Before removing the control it is necessary to switch into edit mode (Icon in the upper right corner). Thereafter it is possible to click on the control and press the delete key to remove the control.
