Stacked area chart

    A stacked area chart shows how a single or multiple measures change over time. The area between the axis and the line is filled with color to indicate volume. If multiple data categories are displayed, they overlap. The top line represents the sum of all the measures.

    Use this chart type to see totals by category. For example, the total of sales by product category.

    1. Open the All workbooks overview page and select your workbook.

    2. Open the dashboard to which you want to add a chart.

    3. In the upper-right corner, click Edit.

    4. Click AddChart (Wizard). You'll see the chart creation wizard.

    To open chart settings, click to the right of the chart type above the wizard slot fields. You'll see a dialog window with the following controls:

    Control Default state Description
    Header On Displays the specified text in the centered line above the chart.
    Legend On Displays the field name associated with color line below the chart.
    Sum in tooltips On Displays the sum of the values of all the lines on data point hover.
    Navigator Off Displays the Navigator for selected lines below the chart.
    Labels overlap Off Allows the labels with a large amount of text to overlap.
    Use with caution - this may negatively affect the labels readability.

    After managing the controls, click Apply to see the results on the chart preview.

    To open slot settings, click in a row with the slot name.

    X and Y axes:

    Setting Description Possible values
    Axis title Sets an axis label. Auto: Uses a field name. If the section contains several fields, Visualization uses the name of the field added to the list first.
    Manual: Allows you to enter an axis title manually.
    Off: Axis will have no label.
    Axis type Sets the axis type. The setting is available for fields in the axis section that have the Fractional number type. Linear: Sets a linear axis type.
    Logarithmic: Sets a logarithmic axis type, preferable for charts with a wide range of values. A logarithmic axis allows you to display a fast-growing graph in a convenient form for analysis, reducing values by order of magnitude.
    Grid Displays a grid on the chart. On: Displays the grid.
    Off: Hides the grid.
    Grid step Sets the grid spacing in pixels. Auto: Sets the grid size automatically.
    Manual: Allows you to set the grid size in pixels.
    Labels Displays data field labels on the chart. On: Displays labels.
    Off: Hides labels
    Labels view Sets the appearance of the label display. The setting is available if the Labels setting is set to On. Auto: Positions label values automatically.
    Horizontal: Positions label values horizontally.
    Vertical: Positions label values vertically.
    Angle: Displays label values at a 45-degree angle.
    Empty values (null) Specifies how to process empty values.
    Not supported by Scatter chart.
    Ignore: Doesn't display empty values in a chart.
    Connect: Joins values of fields that have empty values between them.
    Display as 0: Displays empty values in charts as zero (0) field values.
    Scaling Sets the scale of chart axes. Auto: Sets the scale automatically. You can specify how Visualization sets the scale: from the minimum to the maximum field values (Autoscale from min to max) or from 0 to the maximum field value (Autoscale from 0 to max).
    Manually: Allows you to set the axis scale manually. You can set the maximum and minimum values along the axis. Visualization trims the chart lines by this value.

    Colors:

    On the left, you can select a line from a data source in the Colors slot of your chart.

    On the right, you can select a color scheme and a color for the line. Select AUTO to let Visualization do the coloring for you.

    • When visualizing multiple measures, consider which of them needs the most attention. For better readability, put the most important measure at the bottom of the fields list - this way, it'll be located at the base of the chart:

    • To display the values for each data point, drag Measure values to the Signatures section.
