Hello everybody,
I have a problem to plot a bar chart with a line plot. Basically, it does not plot the line (although it is not necessary, I just need the marker).
Which is the problem? Here my function:
x=["24h","48h","72h"];
y= [0.59 0.78; 0.61 0.84; 0.74 0.98];
yyaxis left
bar(x,y)
ylim([0 1])
ylabel('Y_{EtOH} [g/g]');
legend 'no adapted' 'adapted';
C= orderedcolors("reef");
colororder(C(2:3,:));
hold on
yyaxis right
names={'24h';'48h','72h'};
x=["24h","48h","72h"];
y2= [0.74 0.74; 0.44 0.57; 0.37 0.44];
plot(x,y2,'LineStyle',"none");
set(gca,'xtick',1:3,'xticklabel',names);

plot expects the inputs as numerical values.
You can plot the values directly, for which the x-values will be the corresponding indices.
y= [0.59 0.78; 0.61 0.84; 0.74 0.98];
bar(y)
ylim([0 1])
ylabel('Y_{EtOH} [g/g]');
legend 'no adapted' 'adapted';
C = orderedcolors("reef");
colororder(C(2:3,:));
%corrected v
names={'24h';'48h';'72h'};
hold on
y2= [0.74 0.74; 0.44 0.57; 0.37 0.44];
plot(y2, '*', 'HandleVisibility', 'off');
set(gca,'xtick',1:3,'xticklabel',names);

x=["24h","48h","72h"];
y= [0.59 0.78; 0.61 0.84; 0.74 0.98];
yyaxis left
bh = bar(x,y);
ylim([0 1])
ylabel('Y_{EtOH} [g/g]');
C = orderedcolors("reef");
colororder(C(2:3,:));
hold on
yyaxis right
names={'24h';'48h';'72h'};
x=["24h","48h","72h"];
Cx = categorical(x);
y2= [0.74 0.74; 0.44 0.57; 0.37 0.44];
plot(Cx, y2, '*');
set(gca,'xtick',Cx,'xticklabel',names);
legend(bh, {'no adapted' 'adapted'}, 'location', 'north');

Not when you are using categorical x for the bar() call: when you do that then plot() coordinates can only be category names without any offset.
You would need to switch to using numeric x for the bar() call, knowing that your settting xticks is going to give the appropriate label. After that it would be a matter of figuring out where the bar positions are; that could either be estimated or could be done by examining the graphics objects created by the bar() call.
