在 MATLAB Online 中打开

Hi! How can I enter the correct values into the y-axis on the right? They must match the values of CountArray(:,3)!

load CountArray_1.mat
CountArray = CountArray_1;
x = CountArray(:,1).';
y = CountArray(:,2);
% x = CountArray(:,3).';
% y = CountArray(:,2);
figure
    
E = barh(x,y,'FaceColor',[1 0 0],'EdgeColor',[0 0 0]);
yyaxis left
ylabel('Values A', 'FontSize', 13);
yyaxis right
ylabel('Values B', 'FontSize', 13);
xlabel('Rep', 'FontSize', 13)

Also, is it possible to impose the color black and not orange as shown in the figure?

在 MATLAB Online 中打开

CountArray_1.mat

load CountArray_1.mat

CountArray = CountArray_1;

x = CountArray(:,1).';

y = CountArray(:,2);

% x = CountArray(:,3).';

% y = CountArray(:,2);

figure

E = barh(x,y,'FaceColor',[1 0 0],'EdgeColor',[0 0 0]);

yyaxis left

yticks(x) % optional, depending on what you want to see

ylim([x(1)-1 x(end)+1])

ylabel('Values A', 'FontSize', 13);

yyaxis right

set(gca(),'YColor','k')

yticks(CountArray(:,3)) % optional, depending on what you want to see

ylim([CountArray(1,3)-1 CountArray(end,3)+1])

ylabel('Values B', 'FontSize', 13);

xlabel('Rep', 'FontSize', 13)

Wow, that is confusing. As a consumer of your data visualization, that would be very confusing for me to interpret.

What I'd recommend is if you want the third column to be associated with each bar, then use text to place the number from the third column just to the right of the bar. Let me know if you can't figure that out.

To change just about anything in a graph (font size, color, etc.) see attached demo.
