MATLAB: What happend about the plotting style

graphr2014bgraphics

As I know that starting in R2014b, MATLAB graphics titles use a bold and slightly larger font for better visibility. I am using R2014b, what happend to my plotting style?

The left is a example picture from help center, the right is my plotting. You can see the difference between the titles.

What happens if you do the following?

get(gca,'FontSize')
get(get(gca,'Title'),'FontSize')
get(get(gca,'Title'),'FontWeight')

My guess is that it's going to be something interesting about your font, so you should probably also do this:

get(gca,'FontName')

MATLAB: Line marker specifiers duplicated – subplot legend

Are you sure you're not just seeing your plots behind the legend? Things are pretty crowded in that tiny axes. What happens if you add this:

set(get(gca,'Children'),'Visible','off')

to hide the plots in that axes.

BTW, I don't think your code actually matches the picture. Your code doesn't do "hold on" until after you plot p2. That means that plotting p2 would have overwritten p1. And yet we can see some square markers.

Use the legend function after the three plots

close all
k = input('Number of frequency points = ');     %%256
w = 0:pi/k:pi;
alpha=0.3
num=((1-alpha)/2)*[1 1]
den=[1 -alpha]
hlp=freqz(num,den,w)
num1=((1+alpha)/2)*[1 -1]
den1=[1 -alpha]
hhp=freqz(num1,den1,w)
figure
subplot(2,1,1)
plot(w/pi, abs(hlp),'k','LineWidth', 2);hold on
grid on;
xlabel('\omega/\pi', 'FontSize', 12, 'FontWeight', 'Bold')
ylabel('Amplitude', 'FontSize', 12, 'FontWeight', 'Bold')
title('|H(\omega)|', 'FontSize', 12, 'FontWeight', 'Bold')
set(gca, 'FontSize', 14, 'FontWeight', 'Bold')
plot(w/pi, abs(hhp), 'LineWidth', 2);hold on
grid on;
xlabel('\omega/\pi', 'FontSize', 12, 'FontWeight', 'Bold')
ylabel('Amplitude', 'FontSize', 12, 'FontWeight', 'Bold')
title('|H(\omega)|', 'FontSize', 12, 'FontWeight', 'Bold')
set(gca, 'FontSize', 14, 'FontWeight', 'Bold')
plot(w/pi, abs(all_pass),'r', 'LineWidth', 2);hold on
grid on;
xlabel('\omega/\pi', 'FontSize', 12, 'FontWeight', 'Bold')
ylabel('Amplitude', 'FontSize', 12, 'FontWeight', 'Bold')
title('|H(\omega)|', 'FontSize', 12, 'FontWeight', 'Bold')
set(gca, 'FontSize', 14, 'FontWeight', 'Bold')
legend ('low pass','high pass','all pass','Location', 'Northwest')
set(legend,'FontSize',7);
