How to plot 4 Tiled plots with 2 x axis and 2 y axis in one figure

I want to plot 4 tiled diagrams in one figure. I already use tiledlayout to creat a secon x axis. The first diagram is correct, but when I try to plot the second diagram next to the first (using tiled layout again) only an empty diagram appears and the data from the second diagram are plottet in the first diagram.

How can i plot 4 of those diagramms like the first in one figure?

% Al2O3 für alle EF

% EF 4 mm

tmp = readtable('project.xlsx', 'Sheet', '4');

x1= table2array(tmp(:,12));

y1= table2array(tmp(:,2));

x2= table2array(tmp(:,25))

y2= table2array(tmp(:,15));

y3= table2array(tmp(:,3));

y4= table2array(tmp(:,16));

figure()

t = tiledlayout(2,3);

t1=tiledlayout(t,1,1)

ax1 = axes(t);

plot(ax1,x1,y1,'or')

ax1.XColor = 'r';

ax1.YColor = 'r';

set ( gca,'XLim', [0, 4])

xlabel('Thickness [mm]')

ylabel('w/w [%]')

ax2 = axes(t);

plot(ax2,x2,y2,'ok')

ax2.XAxisLocation = 'top';

ax2.YAxisLocation = 'right';

ax2.Color = 'none';

ax1.Box = 'off';

ax2.Box = 'off';

set ( gca,'XLim', [0, 4], 'XDir', 'reverse' )

set ( gca,'YLim', [0, 0.525])

xlabel('Thickness [mm]')

ylabel('w/w[%]')

nexttile;

t2=tiledlayout(t,1,1)

ax1 = axes(t);

plot(ax1,x1,y2,'or')

ax1.XColor = 'r';

ax1.YColor = 'r';

set ( gca,'XLim', [0, 4])

xlabel('Thickness [mm]')

ylabel('w/w [%]')

ax2 = axes(t);

plot(ax2,x2,y3,'ok')

ax2.XAxisLocation = 'top';

ax2.YAxisLocation = 'right';

ax2.Color = 'none';

ax1.Box = 'off';

ax2.Box = 'off';

set ( gca,'XLim', [0, 4], 'XDir', 'reverse' ) % Hier muss hintere Zahl mit Glas-Dicke (Nenndicke) übereinstimmen

xlabel('Thickness [mm])')

ylabel('w/w [%]')

Hi @Luisa,

Can you share the 'project.xlsx' file, that'll help in reproducing the issue.

[Stephen23]

Rather than creating a sub-table and then calling TABKE2ARRAY like this:

x1 = table2array(tmp(:,12)); 

a simpler way to obtain the table content is to use curly-brace indexing:

x1 = tmp{:,12};

https://www.mathworks.com/help/matlab/matlab_prog/access-data-in-a-table.html

[Luisa]

@Rahul here is the table

Answer 1

[Stephen23]

Do NOT call TILEDLAYOUT multiple times.

Only call TILEDLAYOUT once. After that you call NEXTTILE for each plot.

"I want to plot 4 tiled diagrams in one figure."

Your code specifies two rows and three columns, which thus makes space for six plots:

t = tiledlayout(2,3);

whereas if you really want four plots then you should specify two rows and two columns:

tiledlayout(2,2); % call only ONCE!
[X,Y,Z] = peaks(20);
% Tile 1
nexttile
surf(X,Y,Z)
% Tile 2
nexttile
contour(X,Y,Z)
% Tile 3
nexttile
imagesc(Z)
% Tile 4
nexttile
plot3(X,Y,Z)

[Luisa]

Thanks for the hint. I have a problem with plotting the second axis (y and x) after calling nexttile. How can i plot the second axis correct?

[Stephen23]

Tidying up that workbook would make importing the data simpler and more reliable, e.g.:

• fill out the table starting from cell A1,
• no empty columns,
• no duplicate header names.

T = readtable('project.xlsx', 'Sheet','4', 'Range','L2:P18')

Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

[Luisa]

Thanks so far.

Here is a more cleare tabe (I hope so). I want to plot conc. A_side1 (y axis one) over Thicknes 1 (x Axis one) and in the same diagramm conc.A_side 2 (y axis two) over Thickness 2. Then the nexttile should start the secon plot doing the same with Conc.B side 1 over Thickness 1 and conc.B_side 2 over Thickness 2 (again one diagram)

[Stephen23]

Note the lower case with CONC_A_SIDE1, consistent naming would make data easier to work with.

Thanks for your help, that looks quit good. Now only one more problem exist. T.Thickness2 should have an extra x-Axis because the x-values frome Side 2 (t.Thickness2) must be revers to those of T.Thickness1. Is there any possibility to creat this in the diagramm? (x.axis bottom form 2.6-3.8 for T.Thickness1 and x.axis top from 3.8 to 2.6 for T.Thickness2)

From this page i used the side i get the code to plot to x-Axis. For one figure it is working. But if i want to plot a second figure with multiple x-axis in the same figure it is not working
