Configuring Crossplots

Data Settings

  1. Go to the Data tab.
  2. Name: Enter a name for the crossplot. This name is displayed as the title of the crossplot.
  3. Plot type: Select how to display the crossplotted points
    • Density Plot (Binned): A density plot of the binned results.
    • Point by Point: Colour code the crossplotted points using values from a third data set. This mode may not be appropriate for very large numbers of points.
  4. Horizontal Data Set: Choose the data to define the X axis
  5. Vertical Data Set: Choose the data to define the Y axis
  6. Data Type (horizontal and vertical): Choose the type of data for the axis
    • 3D Volume
    • 2D Volume
    • Horizon
    • Well Curve
    • Vertical Dimension
  7. Data Source (horizontal and vertical): Choose the source of data for the axis, according to the selected Data Type
    • The example shows volumes containing acoustic impedance on the horizontal axis and VpVs on the vertical axis.
  8. Colour Data Set: (for point-by-point plot types) Select the Data Type and Data Source to use for colour values
  9. Select the probe to define the extents of the analysis.
    • Probes are required when crossplotting volumes.

View Settings

  1. Plot type: Select how to display the crossplotted points.
    • Density Plot (Binned): A density plot of the binned results.
    • Point by Point: Colour code the crossplotted points using values from a third data set.
      • Colour values use the Colour Data Set selected in the Data tab.
      • Dot Size: The size of each point in the plot.
  2. Class: The Class settings for the Colour Data Set.
  3. Use min and max from class settings:
    • Enabled: Use the min and max values from the Colour Data Set class.
    • Disabled: Enter minimum and maximum values for the colour range.
  4. Auto adjust values: Enable this option to automatically update the minimum and maximum when the crossplot data changes.
  5. Adjust: click to set the minimum and maximum values from the available data.

Axes Settings

Configure labels, scales and ranges for the horizontal and vertical axes.

Define axes settings
  1. Label: A label for the horizontal and vertical axes.
  2. Range: Minimum and maximum values for the horizontal and vertical axes.
    • Symmetric option: Enable to set minimum and maximum values symmetric around 0, i.e. minimum = maximum * -1
  3. Grid Lines: Adjust the number of horizontal or vertical grid lines.
  4. Flip Axis: Flip the plot on its vertical axis.

Note: To reset the range of the axes, simply right click on the plot and select Zoom to fit.

Polygon and Ellipses

Polygon and ellipse styles can be configured. (see Highlighting crossplot points (from sections), Highlighting geobodies (from crossplots), Using Litho-Fluid Models).
