We have data from ImageJ with angle and distance. We are looking for a tool to plot this on polar coordinates kind of like
http://stackoverflow.com/questions/11250166/matlab-rose-plot-increasing-radial-incrementsWe also have an added component of time such that we'd like to assign colors based on time.
Is there a method to do this in ImageJ or should we look into writing our own?
Here's a very no-frills version of what we are looking for, but with frills...
var scaleFactor = 50; // how long to scale lines on graph
var wedgeAngle = 5 / 180 * PI / 2; // in this example, wedge is 5 degrees wide
macro "radial graph [f4]" {
angles = newArray(85, 115, 83, 78, 90, 95, 15); // in arrays for development; real data from text files
dists = newArray( 3, 4, 2.5, 1, 3.25, 2, 1.5);
times = newArray( 0, 0, 0, 1, 1, 2, 3);
colors = newArray("red", "magenta", "cyan", "green", "yellow"); // change from names to numbers
newImage("plot", "RGB black", 512, 512, 1);
xc = 256;
yc = 256;
a = newArray(2);
x = newArray(2);
y = newArray(2);
for (i=0; i<angles.length; i++) {
angle = (angles[i] / 180) * PI;
a[0] = angle-wedgeAngle;
a[1] = angle+wedgeAngle;
for (k=0; k<a.length; k++) {
x[k] = xc + dists[i] * sin(a[k]) * scaleFactor;
y[k] = yc + dists[i] * cos(a[k]) * scaleFactor;
run("Colors...", "foreground=" + colors[(times[i])] + " background=black selection=cyan");
} // for k (makes the wedge)
makePolygon(xc, yc, x[0], y[0], x[1], y[1]);
run("Fill", "slice");
} // for i
run("Select None");
} // end macro
Thank you!!!
