How can I put table cells in a plot title?

I have two different table that contain data of variables. The first one contains the values and times of the variables and the second one contains the unit and the decimal point of each of the variables that I want to plot ( see the picture).

I have already made a loop that plots the data. I am trying to write something that compares the two tables, and then if the variable columns have both the same value (e. g. the same name of the variable), the unit and decimal point gets added into the plot title. This was my first idea:

    Var1=T.Variable; %variable name column of the first table
    Var2=AuswertungVorlage.Variable;%the variable name column of the second table
    if cellfun(@isequal, Var1, Var2) %comparing both columns
    title(Var1) %wrong and not completed.

The title that I would like to be printed should look somewhat like this : Variablename [unit] * 10^(decimal point).

Thanks a lot in advance for the help!

hello

you have to convert your cells into string first and then concatenate the strings elements in one larger string - this you can put in the title command

Hi Mathieu,

okay I converted them into a string through the string function, the code executes without errors but the plots are with no titles. Here is the complete loop:( U countains the array of the variables that get plotted), apparently title(string(U(k)) is not wrong, but the complicated thing is that I want to put not only the variable name but also the unit and the decimal factor:[unit] * 10^(decimal point)

Thanks a lot for the help :)

for k = 1:numel(U)
X = T.Variable==U(k);

Uhrzeit = round(seconds(T.Time(X)/1000));
Uhrzeit.Format='hh:mm:ss';
Uhrzeit = sort( Uhrzeit,'ascend');
Wert = T.Value(X);

if (answer == 'j')
    ind = find(Uhrzeit >= st & Uhrzeit <= et);
    Uhrzeit = Uhrzeit(ind);
    Wert = Wert(ind);
end

if cell2mat(antwort) == '1'
    freq1=freqbereich1.fb1;
    freq1 = double(split(string(freq1(1:end-1)) , "."));
    freq1 = freq1(:,1);
    ftime1=linspace(Uhrzeit(1),Uhrzeit(end),height(freqbereich1));
    freqbereich1.ftime1=ftime1';
    nexttile
    plot(ftime1(1:end-1),freq1);
    hold on 
    plot(Uhrzeit,Wert)
    Var2=string(AuswertungVorlage.Variable);%the variable name column of the second table
    if (U(k) == string(Var2))%comparing both columns
    title(string(U(k))) 
    end
    hold off

I can try to further help but the input data (U) is missing

[Ramo Rafsel]

the input data (U) is the following, which I want to compare with the variables from the table that I uploaded a part of:

U ={'E1_ABD_FEventcnt','E1_LD_Act','H1_PRES_hPa','H2_PRES_S03mmHg','H2_PRESS','H2_TMP'};

I tried the following code, I get however no titles...

    Var2=variableunits.Variable;% the variable name column of the second table
    tf = strcmpi(U(k),Var2);    % if one of the variable names (from u) match the Var2, the result is 1.
    if (tf == true) % if the result is 1 or true -->
    title(Var2,variableunits.unit,variableunits.Faktor)% --> plot the varable name, with the unit and the faktor                                          
    end
    hold off

Hello,

From my understanding, you are trying to set the title of the plot with the values that are retrieved from any specific cells of the table.

Here is a sample code:

% Declaring some values for the table
Variable = {'H2TEMP';'H1TEMP'};
Decimal = [3;4];
units = {'mS/cm';'mS/cm'};
% Creating a sample table with some values
T = table(Variable, Decimal, units);
% Creating a string with the table values
titleString = append(T.Variable{1},' ',T.units{1}, num2str(T.Decimal(1)));
plot((1:10).^2);
% Puts the string created above as the title of the plot
title(titleString);

Here, the values from the first row of the table are retrieved and concatenated to form a string. This string is then passed onto the title of the plot.

The title in the output plot looks like this:

NOTE:

1. num2str() is used to convert a number to a character array, which is useful while concatenating the strings.
2. append() is used to combine strings
