MATLAB: How to change marker size when plotting

markersizeplot

I want to change the marker size and line width for my following plot:
function [fitresult, gof] = createFit(diameter, time)
%CREATEFIT(DIAMETER,TIME)
%  Create a fit.
%
%  Data for 'Raw Data' fit:
%      X Input : diameter
%      Y Output: time
%%Fit: 'Raw Data'.
[xData, yData] = prepareCurveData( diameter, time );
% Set up fittype and options.
ft = fittype( 'power1' );
opts = fitoptions( 'Method', 'NonlinearLeastSquares' );
opts.Display = 'Off';
opts.StartPoint = [155.522818446907 -1.88432816467686];
% Fit model to data.
[fitresult, gof] = fit( xData, yData, ft, opts );
% Plot fit with data.
figure( 'Name', 'Raw Data' );
h = plot( fitresult,'b', xData, yData, '.k', 'MarkerSize',10);                   %Works without 'MarkerSize',10 but not with it
legend( h, 'time vs. diameter', 'Raw Data', 'Location', 'NorthEast' );
% Label axes
xlabel diameter
ylabel time
grid on
hold on;
axis([0 22 0 41]);

Best Answer

h = plot( fitresult,'b', xData, yData, '.k', 'MarkerSize',10);
Looks like you've exceeded the smarts of the enhanced plot command; granted it looks like it might should work but I don't see that the extra named parameters are actually listed in the doc.
I'm guessing you'll need to go at it in two steps; either separate the fit and the data plots initially or
hL=plot(fitresult,'b', xData, yData, '.k');  
hL(1).'MarkerSize'=10;
I'm guessing will work....might be worth a support request unless somebody sees something I missed. Complexity has its paybacks in adding all these objects and so on--the interfaces just get more and more convoluted.
Addendum Test above; does work with the correction that it's hL(1) that's the data line, not hL(2) I had presumed first based on order in the argument list.
Worth a query to TMW on whether the original should work or not; I'm not positive altho I'm guessing they'll say "no"...
