But the output is not quite giving me what I want: What's going on here? The SCATTER function expects its 'S' parameter to contain the marker area in points squared. The properties have changed in R2015a release. The scatter() function only allows one marker definition so the data are plotted within a loop that iterates through a list of markers. Why is scatter so slow for variable marker size?. When C is a vector the same length as X and Y, the values in C are linearly mapped to the colors in the current colormap. Default is rcParams['lines.markersize'] ** 2. c: color, sequence, or sequence of color, optional. Per the documentation, scatter marker size property is marker proportional to area while the line marker property is proportional to diameter.The default values are 36 and 6 points, respectively, so they are the same visually by default.
