(Defined in: jpgraph_scatter.php : 64)
Class usage and Overview A variant of scatter plot is the so called Field Plots this is
basically a scatter plot where each scatter point is an arrow with a
direction between 0 to 359 degrees. This effectively allows the
visualization of 3 parameters at each point (x,y,angle). As an
additional bonus there is also possible to define a callback for each
scatter plot to also define the color for each point.

Class Methods
Description Create a new instance of a field plot Example
Description Specify a callback that gets clled for each arrow in the field plot
The callback should return an array with the elements
Example // teh further we get from the pole function FldCallback($x,$y,$a) { $polex=4; $poley=40; $maxr = 3000; // Size and arrow size is constant $size=""; $arrowsize=""; // Since we have different scales we need the data points // to be of the same magnitude to give it a distance // interpretation. $x *= 10; // Colors gets colder the further out we go from the center $r = ($x-$polex*10)*($x-$polex*10)+($y-$poley)*($y-$poley); $f = $r/$maxr; if( $f > 1 ) $f=1; $red = floor((1-$f)*255); $blue = floor($f*255); $color = array($red,0,$blue); return array($color,$size,$arrowsize); } // Setup the field plot $fp = new FieldPlot($datay,$datax,$angle); // Setup formatting callback $fp->SetCallback('FldCallback');
