    Remarks

    If a dashboard item is bound to a large dataset, the Web Dashboard limits visible data to speed up the rendering of the visual elements when you design a dashboard. First, the dashboard control obtains the underlying data and performs all required calculation. After the calculation process, the control renders the visual elements. At this point, if the number of the data item’s unique values is larger than a certain number N, the dashboard control uses only the first N values to render the elements. The number varies for each dashboard item.

    The image below shows the difference between a chart that displays limited visible data and a chart that displays all data:

    Chart with Limited Visible Data vs. Chart with Complete Visible Data

    Initially, the Web Dashboard limits visible data only in Designer mode. To change the settings, specify the LimitVisibleDataMode property value:

    <DxDashboard Endpoint="api/dashboard" style="width: 100%; height: 100%;"
                 LimitVisibleDataMode="DevExpress.DashboardWeb.LimitVisibleDataMode.DesignerAndViewer">
    </DxDashboard>
