Figure 12.16 Drawing a Polygon
Contours
A related command, In Polygon, tells whether a given point falls inside the polygon specified. This code
checks some points from the JMP man pictured in Figure 12.16.:
In Polygon(0,60, GcoordX,GCoordY); //returns 0
In Polygon(30,38, GcoordX,GCoordY); //returns 1
Or you can add In Polygon to the JMP man script. Run this script, and then click various locations in the
picture and watch the Log window.
new window("The JMP man",
graph box(framesize(300,300), xscale(-10,80),yscale(-10,80),
pen color("black"); fill color("black");
polygon(gCoordX, gCoordY);
mousetrap({},print(if(in polygon(x,y,gCoordX,gCoordY),"in","out")))));
Contour draws contour lines using a grid of coordinates. Its syntax is:
Contour(xVector,yVector,zGridMatrix,zContour,);
Given an n by m matrix zGridMatrix of values on some surface, defined across the n values of xVector
by the m values of yVector, this function draws the contour lines defined by the values in zContour in
the colors defined by zColors.
// testContour
x = (-10 :: 10) / 5;
y = (-12 :: 12) / 5;
grid = J( 21, 25, 0 );
z = [-.75, -.5, -.25, 0, .25, .5, .75];
zcolor = [3, 4, 5, 6, 7, 8, 9];
