Double bar chart graphic

  • Last UpdatedSep 12, 2025
  • 6 minute read

A double bar chart graphic shows two sets of data side by side for easy comparison. Each category on the x-axis features two bars—one for each data set—grouped together. This arrangement gives you a visual comparison of the values within the same category.

Example

The following double bar chart graphic has its NumberofItems property set to Twelve.

Configure the graphic

Configure the following properties for this graphic:

  • Follow asset context - The asset context affects properties that are configured to display asset stream ref data and asset metadata. When this is enabled:

  • Follow time context - When this is enabled:

    • If this content is in a visualization, it uses the visualization's time context as the time range for the data it displays. For details, see Create a new visualization.

    • If this content is in an experience, it uses the time selected in the time selector content item as the time range for the data it displays. For details, see Add a time selector.

  • Time - If Follow time context is disabled, select the time range for the data displayed in the content item.

  • In the Options section:

    • NumberOfItems - The number of data points to display on the chart.

      This changes the number of some properties available.

    • Statistics - The retrieval mode for the graphic.

      If Current is selected, configure the DataPoint property for each data point. If another option is selected, configure the DataPointReference, StartTime, and DataPointDuration properties for each data point.

      See Understand retrieval mode for details.

    • ColorA - The color of the bars for the first set of data points.

    • ColorB - The color of the bars for the second set of data points.

    • ShowTitleAs - Enables the Title property in the Graphic Properties section to set the graphic title and sets the font size.

      Title is a larger font. Subtitle is a smaller font.

    • ShowTimeProperties - Enables the DataPointDuration property.

      This option is not available when Statistics is Current or Simulation is enabled.

    • Limits - Enables limits for the graphic.

      If enabled, the HiHiLimit, HiLimit, LoLimit, LoLoLimit, and TargetLimit properties are available.

    • HiHiLimit - Enables the high alert limit for the graphic.

      This is available when Limits is enabled. If enabled, the HiHiLimit property in the Graphic Properties section is available.

    • HiLimit - Enables the high warning limit for the graphic.

      This is available when Limits is enabled. If enabled, the HiLimit property in the Graphic Properties section is available.

    • LoLimit - Enables the low warning limit for the graphic.

      This is available when Limits is enabled. If enabled, the LoLimit property in the Graphic Properties section is available.

    • LoLoLimit - Enables the low alert limit for the graphic.

      This is available when Limits is enabled. If enabled, the LoLoLimit property in the Graphic Properties section is available.

    • TargetLimit - Enables the target value for the graphic.

      This is available when Limits is enabled. If enabled, the Target property in the Graphic Properties section is available.

    • ShowLabels - Displays the numeric scale for the x-axis.

    • ShowUOM - Enables units of measure for the x-axis, if ShowLabels is enabled.

      Set the UOM property in the Graphic Properties section.

    • ShowAxisNames - Enables labels for the axes on the graphic, if ShowLabels is enabled.

      Set the XAxisName and YAxisName properties in the Graphic Properties section.

    • ShowLegends - Enables legends for the data sets.

      If enabled, set the Legend property for each data set.

    • ShowValues - Displays the values for the data points.

    • ShowCard - Displays a colored background behind the graphic.

    • Simulation - Displays test data for the graphic.

      If enabled, the Statistics and DataPoint properties are not available but the SimMax, SimMin, and SimPeriod properties are available.

  • In the Graphic Properties section:

    • DataPoint1A-12B - The data point or value for each bar on the graphic, starting from the center.

      This is available when Statistics is Current and Simulation is disabled. The number of properties available is based on the NumberOfItems selected.

      To select a data stream, select the field and then select the pencil icon. In the DataPoint window, select Streams. In the Search window, use the filters to find and then select the stream, asset stream reference, or asset metadata to display.

    • DataPointDuration - The period, in minutes, used when calculating statistics.

      This is available when Statistics is not Current and ShowTimeProperties is enabled. It can't be zero, but it can be negative when a StartTime is specified.

    • DataPointReference1A-12B - The data point or value for each bar on the graphic, starting from the center.

      This is available when Statistics is not Current and Simulation is disabled. The number of properties available is based on the NumberOfItems selected.

      To select a data stream, select the field and then select the pencil icon. In the DataPointReference window, select Streams. In the Search window, use the filters to find and then select the stream, asset stream reference, or asset metadata to display.

      Ensure the Data Binding Mode is Constant when configuring DataPointReference1A-12B in combination with Statistics.

    • Decimals - The number of decimal places for the data point value, up to 2.

      Invalid values are discarded.

    • HiHiLimit - The value above which a high alert color appears on the graphic.

      This is available when HiHiLimit is enabled.

    • HiLimit - The value above which a high warning color appears on the graphic.

      This is available when HiLimit is enabled.
