Sorry for asking stupid questions, but I'm not getting it

Main Problem: Bar chart is always overlaying line plot

Month = [1 2 3 4 5 6 7 8 9 10 11 12]
Temp = [15.8 15.8 15.8 15.7	15.8 15.1 14.7 14.6	15.0 15.7 16.2 16.1]
Prec = [88.0 108.4 129.3 169.5 197.3 212.9 204.3 145.6 121.0 116.2 101.3 99.9]
 left_color = [0 0 0]
 right_color = [0 0 0]
 set(figure(1),'defaultAxesColorOrder',[left_color; right_color]);
hold
xticks([1 2 3 4 5 6 7 8 9 10 11 12])
 xlabel ('Monate')
h1=plot(Month,Temp,'color','r')
axis ([1 12 0 30])
yyaxis right
axis ([1 12 0 300]) 
h2=bar(Month,Prec,'b')  

I know, this alreasy looks confused, because I am, I changed everything thousand times, now I'm absolutely coinfus.

What I was trying to do:

Plotting a line graph and bars in oine figure. Line graphe in foreground.

Left yaxis for the Line Graph

Right yaxis for the bars

bars blue, line red

So far, everythign worked but I'm not managing to bring the Line graph to the foreground

Help needed. Thank you

This is actually not a newbie issue...

As far as I know, it's a known issue with yyaxis.

A workaround by @Charles Brown using two axes taken from here works very well

figure(42);
clf();
Month = [1 2 3 4 5 6 7 8 9 10 11 12];
Temp = [15.8 15.8 15.8 15.7	15.8 15.1 14.7 14.6	15.0 15.7 16.2 16.1];
Prec = [88.0 108.4 129.3 169.5 197.3 212.9 204.3 145.6 121.0 116.2 101.3 99.9];
% first init the left & right axes, give both the same position
% left axis needs to be created second to be on top.
rightAx = axes('Position',[0.1300 0.1100 0.7750 0.8150]);
leftAx = axes('Position',[0.1300 0.1100 0.7750 0.8150]);
xticks([1 2 3 4 5 6 7 8 9 10 11 12]);% not necessary really
xlabel ('Monate');
h1=plot(Month,Temp,'color','r');
axis ([0 13 0 30]);
% yyaxis right
subplot(rightAx);
h2=bar(Month,Prec,'b');
% Need to move the Y-axis after plotting the foreground data for some
% reason.
rightAx.YAxisLocation = 'right';
% Now we have to set the background of the front axis to be transparent.
set(leftAx, 'Color', 'None');

still need some playing with the tick marks but it's a good start

Thank you again for your help.

This really works out for me!

I created a little Matlab Script for plotting climate diagrams (as you already have seen).

The final code looks like this:

figure(1);
clf();
Month = [1 2 3 4 5 6 7 8 9 10 11 12]; %Monate
Temp = [15.8 15.8 15.8 15.7	15.8 15.1 14.7 14.6	15.0 15.7 16.2 16.1]; %Temperaturdaten
Prec = [88.0 108.4 129.3 169.5 197.3 212.9 204.3 145.6 121.0 116.2 101.3 99.9]; %Niederschlkagsdaten
x=['J','F','M','A','M','J','J','A','S','O','N','D'] %Label nach Monaten
%%Workaround um Line über Bar zu plotten
% first init the left & right axes, give both the same position
% left axis needs to be created second to be on top.
rightAx = axes('Position',[0.1300 0.1100 0.7750 0.8150]);
leftAx = axes('Position',[0.1300 0.1100 0.7750 0.8150]);
xlabel ('Monate');
h1=plot(Month,Temp,'color','r','LineWidth',2); 2
set(gca,'XTickLabel',[])
axis ([1 12 0 30]); %Limits der Achsen
ylabel('Temperatur in °C')
% yyaxis right
subplot(rightAx);
h2=bar(Month,Prec,'b'); 
axis ([1 12 0 300]);
% Need to move the Y-axis after plotting the foreground data for some
% reason.
rightAx.YAxisLocation = 'right';
 y=ylabel('Niederschlag in mm', 'rot', 270);  % Y Label rechts (Niederschlag) und Drehung um 270°
set(y, 'position', get(y,'position')+[0.4,0,0]);  %Label für Y Achse um 4 pt nach rechts
% Now we have to set the background of the front axis to be transparent.
set(leftAx, 'Color', 'None');
set(gca,'xticklabel',x.') %Ticks werden durch Vektor x (Monate) benannt
title('Klimadiagramm Sibundoy') 

This is for a place in colombia, no negative temperatures. But in other there are of course.

It should look like this: https://images.climate-data.org/location/81/climate-graph.png

Is there any possibility to ajust the x and y axis for negaive Temperatures?

Okay, I think, i got it:

figure(1);
clf();
Month = [1 2 3 4 5 6 7 8 9 10 11 12]; %Monate
Temp = [-3.3 -1.7 2.9 10.2 16.1 19.4 20.9 20.5 16.2 10.1 4.4 -0.3]; %Temperaturdaten
Prec = [40 38 35 42 51 75 69 45 48 27 39 38 ]; %Niederschlkagsdaten
x=['J','F','M','A','M','J','J','A','S','O','N','D'] %Label nach Monaten
%%Workaround um Line über Bar zu plotten
% first init the left & right axes, give both the same position
% left axis needs to be created second to be on top.
rightAx = axes('Position',[0.1300 0.2350 0.7750 0.9150]);
set(rightAx, 'Color', 'None');
leftAx = axes('Position',[0.1300 0.1100 0.7750 0.9150]);
%xticks([1 2 3 4 5 6 7 8 9 10 11 12]);% not necessary really
%set(gca,'xticklabel',x.')
xlabel ('Monate');
h1=plot(Month,Temp,'color','r','LineWidth',2); %Plotten der Temperaturkurve Stärke 2
set(gca,'xticklabel',x.') %Ticks werden durch Vektor x (Monate) benannt
axis ([1 12 -5 30]); %Limits der Achsen
ylabel('Temperatur in °C')
% yyaxis right
subplot(rightAx);
h2=bar(Month,Prec,'b'); %Plotten der Säulen für den Niederschlag
axis ([1 12 0 300]); %Limits der Achsen
% Need to move the Y-axis after plotting the foreground data for some
% reason.
rightAx.YAxisLocation = 'right';
 y=ylabel('Niederschlag in mm', 'rot', 270);  % Y Label rechts (Niederschlag) und Drehung um 270°
set(y, 'position', get(y,'position')+[0.4,0,0]);  %Label für Y Achse um 4 pt nach rechts
% Now we have to set the background of the front axis to be transparent.
set(leftAx, 'Color', 'None');
%set(gca,'xticklabel',x.') %Ticks werden durch Vektor x (Monate) benannt
set(gca,'xtick',[])
title('Klimadiagramm Chisinau') %Titel Klimadiagramm
set(gcf,'color','w');

edit: almost, now its the ticks of the y axes :D

The ticks on the right y axis should be always 10 times the tick on the left side:

limits like this:

left -5 --> right -50

left 30 --> right 300
