Data Set with multiple markers, how do I get the legend to display this?

3 views (last 30 days)
I have a data set I've been playing with that has low energy observations and high energy observations. I was wanting to display the low energy data with the '*', and the high energy data with the '^'.
Here's the code I've got:
function [fitresult, gof] = createFit1(xdata1, ydata1)
HeliumData_Voyager
%CREATEFIT1(XDATA1,YDATA1)
% Create a fit.
%
% Data for 'untitled fit 1' fit:
% X Input : xdata1
% Y Output: ydata1
% Output:
% fitresult : a fit object representing the fit.
% gof : structure with goodness-of fit info.
%
% See also FIT, CFIT, SFIT.

%%Fit: 'untitled fit 1'.
[xData, yData] = prepareCurveData( xdata1, ydata1 );
% Set up fittype and options.
ft = fittype( '1/(a*(x)^b+c*(x)^d+e*(x)^f)', 'independent', 'x', 'dependent', 'y' );
opts = fitoptions( 'Method', 'NonlinearLeastSquares' );
opts.Algorithm = 'Levenberg-Marquardt';
opts.Display = 'Off';
opts.Robust = 'Bisquare';
opts.StartPoint = [0.5 0.165607687252584 0.777847540631553 0.913375856139019 0.63235924622541 0.0975404049994095];
% Fit model to data.
[fitresult, gof] = fit( xData, yData, ft, opts );
% Plot fit with data.
figure( 'Name', 'untitled fit 1' );
h1 = plot(fitresult, xData(1:14), yData(1:14),'*');
hold on
h2 = plot(fitresult, xData(15:27), yData(15:27), '^');
hold off
hold on
h3 = plot(fitresult);
set(gca,'XScale','log')
set(gca,'YScale','log')
axis([.001,100,.00001,20])
legend( h1, 'Voyager Data', 'Line of Best Fit', 'Location', 'SouthWest' );
% Label axes

You probably don't need the data set for this question, but for good measure:
xdata1 = [0.0021859258,0.0035637526,0.0049688127,0.007943902,0.012700333,...

0.2899725,0.381267,0.5013045,12.45768,12.954449,15.1476755,14.378171,...
17.712223,19.658836,20.982672,22.395653,30.620895,24.856985,27.95077,...
33.1117,35.805107];
ydata1 = [2.17084,1.5341274,1.6444274,2.4091163,2.025231,2.673546,2.7679887,...
2.5823257,2.3269181,1.8893886,1.3352263,0.8803091,0.5803841,0.42464474,...
4.8200923E-4,3.8242337E-4,2.194412E-4,2.9647112E-4,1.8235153E-4,...
1.3813264E-4,1.0463649E-4,8.496173E-5,4.1460968E-5,6.144804E-5,...
4.875252E-5,3.2894895E-5,2.5501544E-5];
And I'll attach the graph, where you can see I've already got the stars and triangles. However, I can't get the legend to show both types of markers. I want the stars to say Voyager Data, and the triangles to say Pamela Data.
I've tried the following:
legend( [h1,h2], 'Voyager Data', 'Pamela Data', 'Line of Best Fit', 'Location', 'SouthWest' );
However, that didn't work. How can I accomplish this?

Why are you including 'fitresult' in your plotting commands? See if this code does what you want:
function [fitresult, gof] = createFit1(xdata1, ydata1)
% HeliumData_Voyager
%CREATEFIT1(XDATA1,YDATA1)
% Create a fit.
%
% Data for 'untitled fit 1' fit:
% X Input : xdata1
% Y Output: ydata1
% Output:
% fitresult : a fit object representing the fit.
% gof : structure with goodness-of fit info.

ft = fittype( '1/(a*(x)^b+c*(x)^d+e*(x)^f)', 'independent', 'x', 'dependent', 'y' );
opts = fitoptions( 'Method', 'NonlinearLeastSquares' );
opts.Algorithm = 'Levenberg-Marquardt';
opts.Display = 'Off';
opts.Robust = 'Bisquare';
opts.StartPoint = [0.5 0.165607687252584 0.777847540631553 0.913375856139019 0.63235924622541 0.0975404049994095];

plot( xData(15:27), yData(15:27), '^');
plot(fitresult);

That did it! Thanks!
To answer your first, this is simply a lot of iterations of code, so some things I haven't "cleaned" out just yet since I've been working on this code for some time now.
Thanks for the help!

It was their inclusion that prevented legend from functioning the way you expected. Basically, extra axes were being plotted in each 'plot' command.
