JWAVE_CONTOUR Function

This JWAVE wrapper function provides a convenient interface to the PV‑WAVE CONTOUR procedure. This function always returns a Viewable object (a contour plot) to the JWAVE client.

Parameters

This section lists the parameters that the JWAVE_CONTOUR wrapper can retrieve, unpack, and use to produce a contour plot. These parameters correspond to the parameters and keywords of the PV‑WAVE CONTOUR procedure. You must set these parameters in the client application with the JWaveView.setParam method.

Z—(required) A 2D array containing the values that make up the contour surface.

X—A 1D or 2D array specifying the x-coordinates for the contour surface.

Y—A 1D or 2D array specifying the y-coordinates for the contour surface.

Keyword Parameters

This section lists the keyword parameters that can be retrieved and unpacked in this wrapper function.

Nx, Ny—If set to 1, Z (and X and Y) are interpolated from their given size into these dimensions. If set to 0 (the default), the data is not interpolated.

Filled—If set to 1, the space between contours is filled with color. If set to 0 (the default), contours are not filled.

For detailed information on the keywords listed in the following table, refer to Keyword and Named Color Parameters .

Charsize	Max_Value	[XY]Margin
Charthick	NLevels	[XY]Minor
Clip	Noclip	[XY]Range
C_Annotation	Position	[XY]Style
C_Charsize	Spline	[XY]Tickformat
C_Labels	Subtitle	[XY]Ticklen
C_Linestyle	Thick	[XY]Tickname
C_Thick	Tickformat	[XY]Ticks
Follow	Ticklen	[XY]Tickv
Font	Title	[XY]Title
Gridstyle	[XY]Charsize	[XY]Type
Levels	[XY]Gridstyle

Named Color Parameters

These parameters must be set by the JWAVE client Java application with the JWaveView.setNamedColor method.

Returns

This wrapper returns a Viewable object (of a contour plot) to the JWAVE Java client application.

Example

In the client Java application, the setParam method is used to set the parameters to be passed to this JWAVE wrapper on the server. JWAVE_CONTOUR unpacks the parameters and builds a PV‑WAVE CONTOUR command to produce a contour plot.

This Java code sets the name of the wrapper function and some parameters. These lines of code would appear in the JWAVE client application.

JWaveView myJWaveView = new JWaveView(connection, ”JWAVE_CONTOUR”)

myJWaveView.JWaveView.setParam(”X”, elev_data);

myJWaveView.JWaveView.setParam(”CHARSIZE”, 2);

myJWaveView.JWaveView.setParam(”TITLE”, ”Boulder”);

myJWaveView.setNamedColor(”BACKGROUND”, java.awt.Color.blue);
