scatter

For examples, see Matlab Graphics - Scatter Plots.
scatter(x,y,<sz>,<c>) creates a scatter plot with circles at the locations specified by the vectors x and y, sized by sz and colored by c
- Size:
  - To plot every circle at the same size, specify sz as a scalar
  - To use a different size per point, specify sz as a vector with the same length as x and y
- Color:
  - To use a single color for every circle, specify c as a color name or an RGB triplet
  - For varying colors, specify c as a vector or a three-column matrix of RGB triplets
    - Here a vector indexes into the MATLAB Graphics Colormap
scatter(___,'filled') fills in the circles
scatter(___,mkr) specifies the marker type
scatter(___,Name,Value) modifies the chart using one or more name-value pair arguments
scatter(ax,___) plots into the axes specified by ax instead of the current axes
s = scatter(___) returns the Scatter object
