Note: you will need to include CrossPlot in your Module Dependencies list.

A cross-plot data object is a simple data structure that holds a reference for 2 or 3 other data objects. The first two references are for the X and Y components of the cross-plot. The third reference is for the the optional z value that can be used to color the points. The data you specify must implement interface import com.interactive.intviewerapi.data.IXpMember. Currently this interface is implemented for IHorizonData, ISeismicData and IPointSetData.

    import com.interactive.intviewerapi.data.IXpData;

        ....

    IXpData xpData = IXpData.factory.createNewInstance(xdata, ydata, null);

Some data sources may have multiple attributes (horizons, pointset, etc.) and so it may be necessary to specify which attribute you want to use for the cross-plot. For example, if you have an horizon dataset with two attributes, "R0" and "R1" you could build the data source to cross-plot R0 vs R1 as follows:

    IHorizonData hdata = ...

    IXpData xpData = IXpData.factory.createNewInstance(hdata, hdata, null); 

    xpData.setXAttribute("R0");

    xpData.setYAttribute("R1");

If you don't specify an attribute, the default one will be used.

To create the crossplot window, follow this template:

    NamedProps props = new NamedProps();

    String hdata = data.getDataName();

    props.putProperty(IXpLayer.DISPLAY_NAME, lname);

    props.putProperty(IXpLayer.COLOR_MODE, IXpLayer.COLOR_MONO);

    IXpWindow lw = IXpWindow.factory.createWindow();

    IXpLayer layer = IXpLayer.factory.createLayer(lw, data, props, false);

    layer.select(...); // required for display, parameter can be null or a query
