    Gauge Chart
    In This Topic

    A Gauge chart is a Bar chart with a radial axis and overlapping bars to show ranges. It uses the needle and the dial to represent the data. The direction of the needle and the colors in the dial shows the performance at a glance.

    Gauge Plot Properties

    The Gauge Plot properties discussed below can be accessed from the Properties Panel on selecting the Chart > Plot from the Report Explorer. You can access some of the important properties from the Plot's Smart Panel too. See Chart Smart Panels topic for more information. Both the Properties Panel and the Smart Panel can be accessed by right-clicking the plot in the design area.



    The action to perform when the plot is clicked. The action can be a hyperlink, a bookmark, a drill-through, or a slice. For more details on each of these actions, see


    The line style for the column and bar borders.


    The name of the plot. By default, a chart containing a single plot has the plot name as 'Plot1'.



    The Clipping Mode determines how a plot (columns or bars) extends within the plot area. The ClippingMode can be set to

    Gauge Labels

    Gauge labels collection that lets you set the labels, usually to display the exact pointer value.

    Gauge Pointers

    Gauge pointers collection that lets you customize the needle and the needle pin.


    Inner radius of the gauge is the percentage relative to the chart's outer radius.


    The Opacity is the percentage value of the opacity of the plot fill color. 100% opacity means the columns or the bars are opaque while 0% opacity means that they are completely transparent.


    Rules control the appearance of plots based on specified conditions. For more information on conditions, see Rules topic.


    Indicates the arc angle that defines the clockwise rotation of the chart. For Gauge charts, the default is '-45' degrees. A full rotation makes 360 degrees.


    Indicates the arc degrees from 0 to 360 which decides the length of the arc occupied by the plot. For Gauge charts, the default is '270' degrees.


    Gauge chart has only one encoding type.

    Values Encoding

    The Values encoding specifies the data values. This encoding plots the ranges on the gauge's dial. It is important to note that the data value fields should be added in the descending order, for example, 800 > 600 > 400 >200 or the actual field names. In design time, the Values encoding is located below the chart, in the ‘Ranges’ section. See the Create Gauge Chart walkthrough for more information.

    The Values property is the collection of items and each item includes the following properties.


    The Type property provides 'Simple' and 'Complex' options to choose from. However, for Gauge plots, 'Simple' is acceptable.


    The Value property is the collection and usually takes a bound field. However, the Gauge plot takes the first item from the collection.


    To show aggregated values such as Average, Count, and Sum instead of individual values, specify an Aggregate function.
