    Class ScatterPlot

    Representation of a Scatter Plot.

    Scatter plots are used to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another. Each row in the data set is represented by a marker whose position depends on its values in the columns set on the X and Y axes.

    The Scatter Plot supports additional variables corresponding to the color, size, and the shape of the markers to be set, thus adding more dimensions to the plot.

    • Configures a newly created visual with reasonable default values given the current data set.

      Returns void

      This method is called when a visual is created by the user, but the exact configuration produced is undefined and can change between versions. This method should only be used if you want to mimic the user's action in the application, and it should only be called once. It implicity calls Spotfire.Dxp.Application.Visuals.VisualContent.ApplyUserPreferences.
      Code samples on how to create and configure a visualization are available in Spotfire Technology Network. Additional action needed for the Map Chart: in order to load the default layers (i.e. base map layer) you need to explicitly call Spotfire.Dxp.Application.Visuals.Maps.MapChart.AutoConfigureLayers.

      2.0

    • Determines whether the current plot configuration is valid.

      Returns boolean

      true if the current plot configuration is valid; otherwise, false.

Only data tables used by this visualization will be included.

      Returns void

      This will only refresh the data tables where the Spotfire.Dxp.Data.DataTable.NeedsRefresh property is true.
