Publisher review:scatplot - Scatter plot with color indicating data density. Scatter plot with color indicating data densityUSAGE:out = scatplot(x,y,method,radius,N,n,po,ms)out = scatplot(x,y,dd)
DESCRIPTION:
Draws a scatter plot with a colorscale representing the data density computed using three methodsINPUT VARIABLES:x,y - are the data pointsmethod - is the method used to calculate data densities:'circles' - uses circles with a determined area centered at each data point'squares' - uses squares with a determined area centered at each data point'voronoi' - uses voronoi cells to determin data densities default method is 'voronoi'radius - is the radius used for the circles or squares used to calculate the data densities if(Note: only used in methods 'circles' and 'squares'
default radius is sqrt((range(x)/30)^2 (range(y)/30)^2)N - is the size of the square mesh (N x N) used to filter and calculate contours default is 100n - is the number of coeficients used in the 2-D running mean filter default is 5(Note: if n is length(2), n(2) is tjhe number of % of times the filter is applied)
po - plot options:0 - No plot1 - plots only colored data points (filtered)2 - plots colored data points and contours (filtered)3 - plots only colored data points (unfiltered)4 - plots colored data points and contours (unfiltered)default is 1
ms - uses this marker size for filled circlesdefault is 4
OUTPUT VARIABLE:out - structure array that contains the following fields:dd - unfiltered data densities at (x,y)ddf - filtered data densities at (x,y)radius - area used in 'circles' and 'squares'methods to calculate densities
xi - x coordenates for zi matrix yi - y coordenates for zi matrixzi - unfiltered data densities at (xi,yi)zif - filtered data densities at (xi,yi)[c,h] = contour matrix C as described inCONTOURC and a handle H to a contourgroup objecths = scatter points handles
scatplot is a Matlab script for Development Tools scripts design by alex sanchez.
