Newbie: Order of line and plot in a simple figure

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

It works..

Thank you som much....

I spent hours with that issue and couldn't figure out how to solve it.

You saved my weekend :)

Now I'm gonna spend some time, trying to understand what you exactly did :)

edit: Okay, got it... but I would never have found that solution

[Fidelino83]

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

leftAx = axes('Position',[0.1300 0.1100 0.7750 0.8150]);

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?

[TADA]

axis, xlim & ylim should work

I changed the boundaries in line 20 to the following

axis ([0 13 -100 300]);

and it worked as expected

[Fidelino83]

@TADA: Not really

Of course you can change the limit of the left Y axis, my problem is to adjust the X axis of the precipitation. It's position and with it the 0 tick of the right Y axis should still be at the same position as the 0 tick of the left Y axis.

[Fidelino83]

Okay, I think, i got it:

figure(1);

Month = [1 2 3 4 5 6 7 8 9 10 11 12]; %Monate

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

[TADA]

when setting the x limit of both axes to the same values they should be perfectly aligned

axis(leftAx, [-3 15 -10 90]);
axis(rightAx, [-3 15 -30 400]);

there are still some shenanigans with the y axis tic marks but you can play with it to clean them up, or simply remove the box on box axes:

set([leftAx, rightAx], 'Box', 'off');

Wünderschön, endlich habt ihr geschaffen! :)
