You can use the Bar chart to display characteristic values from a database in bars and group them into selected time periods and categories. You can display the data side by side or as a stacked diagram.

Columns

In this section, select the measured values or the value series that are to be sorted or grouped. Use thebutton to open the axis and signal settings in a property window, see Axis scaling and signal assignment.
Group by Signal

Select the category to which the visualized data should be grouped, e.g. material.
Options

Default Aggregation

Determines which operator is used to summarize the values in the aggregation interval:

  • Count: Quantity of values of the selected value series

  • Sum: Sum of values of the selected value series

  • Average: Average of values of the selected value series

  • Minimum: Minimum value of the selected value series

  • Maximum: Maximum value of the selected value series

  • Last value: Parameter display of the last acquired value

  • StdDev: Standard deviation of the selected value series

  • Median: Median of the selected value series

Aggregation Interval

Defines which time range is to be summarized and represented by a bar.

This option allows you to specify a selected time range for the selected value sequence in the bar chart. By default, the bar display is automatic depending on the selected time filter and tile size.

Instead of automatically summarizing the values (A), time-based aggregation allows you to make a targeted selection in time intervals, e.g. year (Y), month (M), day (D) or hour (H). The graph is updated directly. Unlike automatic aggregation, settings made here do not change even if the time range is redefined using the time or zoom filter. Switching is not possible if the grouped view has been selected for a category.

View

Defines the time range that is displayed in the diagram on the time axis:

  • Continuous (C): The view operator is deactivated and the data is displayed continuously over the time range selected as the dashboard filter.

  • Yearly/Monthly/Weekly view: The X-axis represents the selected range (one day, one year or one week).

View Aggregation

Determines which operator is used to summarize the individual values of the intervals in the displayed area (Weekly view, Monthly view or Yearly view).

Sort by

The following sort options are supported for displaying the respective aggregate function:

  • Category asc: sort alphanumerically by category in ascending order

  • Category desc: sort alphanumerically by category in descending order

  • Max. value: sort visualized categories by maximum value in descending order

  • Min. value: sort visualized categories by maximum value in ascending order

Number of categories

Define how many categories should be displayed here.

Show other category

All categories that have not been recorded under Number of categories are summarized under Other.

Show Percentages

Here, the percentage values of the visualized values in relation to the total quantity can be set (only possible in stacked view).

Show Percentages not enabled

Show Percentages enabled




Display legend

Shows the name of the displayed signal and the standard aggregation used.

Display difference

When enabled, the differences from the previous value series or bar are displayed.
