MATLAB: Ticks on second y-axis

Question

Hey there,

I'm one step away from reaching my wanted result. I have a bar chart and tow y-axis. The problem is that the right y-axis won´t accept my "ytricks" command.

Here is the code:

N=5;                             % number of bars
y1=[0,289.17;                    % first data set
    0,507.71;
    0,775.66;
    0,1346.97;
    0,1853.58]; 
y2=[2.36,0;                      % second data set
    3.97,0;
    5.52,0;
    7.72,0;
    8.51,0];   
y1(:,1)=nan;
y2(:,2)=nan;                        % NB: column 2, then column 1 are set NaN for bar chart plotting
x=[1:N].';                          % use the serial index to plot against; transpose
z=plotyy(x,y1,x,y2,@bar,@bar);      % plot, save axes handles
yyaxis left
set(z(2),'xtick',[])                % turn off labels on RH x-axis; keep only one set
ylabel(['Time [s]']);
yticks(0:200:2000);
yyaxis right
yticks(0:1:10);                     % not working !
yl = ylabel('Temperature [°C]');
set(yl, 'Color', 'k');
set(z(1),'xticklabel',[0.5,0.75,1,1.5,2])   % tick labels on first...
xlabel(['Factor']);
l = cell(1,2);                      % legend
l{1}='Time'; l{2}='Temperature';
m = legend(l);
set(m,'FontSize',12);

and here is the result:

Can someone help me scaling the right y-axis (1:1:10)?

Thanks in advance

Answer 1

Either use plotyy or yyaxis

I am demonstrating how to do it with plotyy

z=plotyy(x,y1,x,y2,@bar,@bar);      % plot, save axes handles
% Access axes using set 

set(z(1),'YTick',0:200:2000,'xticklabel',[0.5,0.75,1,1.5,2]);
% Access axes properties directly (you can also use set here)

z(1).YLabel.String = 'Time [s]';
% Access axes using set 
set(z(2),'YTick',0:1:10);
% Access axes properties directly (you can also use set here)
z(2).YLabel.String = 'Temperature [°C]';
xlabel('Factor');
m=legend('Time','Temperature','Location','northwest');
set(m,'FontSize',12);
