I am trying to plot 3 sets of data on the same scatter in 3 different colors but one of them doesn't have a letter code. I need one set unfilled black circles, one set filled grey circles, and one set filled black circles. Whenever I try to plot the grey though I get the error "There is no color property on the Scatter class". I've tried plotting with the plot function to get around this but I get a jumble of lines instead of dots. Does anyone know how to fix this? I've been working around it by selecting the points in the plotter and changing their color but that's tedious and annoying. I've including the code below. Thanks!
scatter(cp1,bd1, "k") % plot connected porosity vs bulkdensity of vdp1 set
hold on
scatter(cp2, bd2, 'color', [0.5 0.5 0.5], 'filled')
hold on
scatter(cp3, bd3, "k", 'filled')

Ran in:
There are two ways to specify the color - as the 4th input or with Name-Value pairs.
To use the 4th input, follow this example from the documentation
x = linspace(0,3*pi,200);
y = cos(x) + rand(1,200);
c = linspace(1,10,length(x));
scatter(x,y,[],[0.5 0.5 0.5],'filled')
Alternately, use the correct property name. Here is an example from the documentation.
theta = linspace(0,2*pi,300);
x = sin(theta) + 0.75*rand(1,300);
y = cos(theta) + 0.75*rand(1,300);
sz = 40;
scatter(x,y,sz,'MarkerEdgeColor',[0 .5 .5],...
'MarkerFaceColor',[0 .7 .7],...
'LineWidth',1.5)
