How do I change the color of a berfit plot? I have two fits that I am plotting on the same graph, and I would like to change the symbol color/shape and line color. I have tried the standard plot color formatting and it hasn't worked and can't find a solution anywhere. I have two arrays of random data to show you the structure of my code:
Temp_x = [
9
8
7
6
5
4
3
];
Temp_y = [
1e-3
5e-3
1e-2
2e-2
3e-2
5e-2
1e-1
];
Temp_y2 = [
2e-3
6e-3
2e-2
3e-2
4e-2
6e-2
1.1e-1
];
figure;
berfit(fliplr(Temp_x'),fliplr(Temp_y')); %transpose and flip data so it would be in the right order for berfit
hold on;
berfit(fliplr(Temp_x'),fliplr(Temp_y2'))
legend('Tempy','Curve Fit', 'Tempy2', 'Curve Fit')
title('Temp Title')
subtitle('Temp Subtitle')
axis([1 15 1e-4 .1])
hold off;
The plot shows this:

hold off;
Get the plotted lines:
h = findobj(gcf,'Type','line')
h =
4x1 Line array: Line (Curve Fit) Line (Tempy2) Line (Curve Fit) Line (Tempy)
Set their colors:
h(1).Color = 'b';
h(2).Color = 'r';
h(3).Color = 'k';
h(4).Color = [0 0.6 0];

You can capture the fit data from berfit and use the normal plot command to plot the data with full control over the symbols, lines, and colors.
Temp_x = [
9
8
7
6
5
4
3
];
Temp_y = [
1e-3
5e-3
1e-2
2e-2
3e-2
5e-2
1e-1
];
Temp_y2 = [
2e-3
6e-3
2e-2
3e-2
4e-2
6e-2
1.1e-1
];
figure;
Temp_x = fliplr(Temp_x'); %transpose and flip data so it would be in the right order for berfit
Temp_y = fliplr(Temp_y');
Temp_y2 = fliplr(Temp_y2');
ber1 = berfit(Temp_x, Temp_y)
ber1 = 1x7
0.1000 0.0500 0.0305 0.0189 0.0106 0.0049 0.0010

ber2 = berfit(Temp_x, Temp_y2);
hp = plot(Temp_x, Temp_y, 'bx', Temp_x, ber1, 'b-', Temp_x, Temp_y2, 'rx', Temp_x, ber2, 'r-');
set(gca, 'YScale', 'log')
grid on
legend('Tempy','Curve Fit', 'Tempy2', 'Curve Fit')
title('Temp Title')
subtitle('Temp Subtitle')
axis([1 15 1e-4 .1])
