How to create isopleths of dissolved oxygen for lake?

ayman

I am trying to create an isopleth of dissolve oxygen for a lake as shown below using JMP. The data I have includes month, depth, and dissolved oxygen.

In JMP there are two methods that might work, depending upon your table setup. Likely a contour is what you want

 

Below is a picture, from JMP sample data Little Pond. Its x axis is spatial distance not time. You will have to customize the color scheme.  A script to create the picture follows.

 

You can produce a contour with Main Menu Graphs > Contour Plot or Graph Builder. Contour plot has more customization.

 

From Contour choose Days and Depth for X and Dissolved Oxygen for Y Ask to fill areas.  You can choose your levels for the Z variable (Dissolved Oxygen).

 

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Little Pond.jmp" );

obj = dt << Contour Plot(
	X( :X, :Y ),
	Y( :Z ),
	Show Data Points( 0 ),
	Fill Areas( 1 ),
	Label Contours( 1 ),
	Transform( "None" ),
	Specify Contours( Min( -4 ), Max( 8 ), N( 7 ) ),
	SendToReport(
		Dispatch( {}, "Contour Plot Graph", FrameBox, {Frame Size( 594, 326 )} )
	)
);
