adding textbox to plot - text doesnt stay in one line

Hi,

i want to add a text box to my chart. I followed the documentation but in my case, the text doesnt stay in one line and I'm wondering how I can resolve this.

It should be 'Biomass = 1.03' and 'Electricity = 2.065'.

    figure()
    hb = bar(out.combinednew{:,1}, [out.combinednew{:,3},out.combinednew{:,9},out.combinednew{:,12}]);
    legend(out.combinednew.Properties.VariableNames([3,9,12]));
    xlabel('Primary Energy Demand');
    xscale = Tmin:2:Tmax;
    xticks(Tmin-2:2:Tmax+2);
    xticklabels({'HP',xscale,'LGB'})
    hb(1).FaceColor = [0.83 0.83 0.83];
    hb(2).FaceColor = [0.4660 0.6740 0.1880];
    hb(3).FaceColor = [0 0.4470 0.7410];
    txt = {'Primary energy factors:','Biomass =' num2str(Basisdaten.Primaerenergiefaktor.Biomasse.today), ...
        'Electricity =' num2str(Basisdaten.Primaerenergiefaktor.Strom.today),};
    dim = [.15 .6 .3 .3];
    annotation('textbox',dim,'String',txt,'FitBoxToText','on');

Furthermore I would like to have subscripted letters in the legend on the top right but I'm reading those out from the labels in a table. Is this possible?

Thanks!

To fix the one-line-text problem, enclose the relevant text in [ ] to make it a single character vector:

txt = {'Primary energy factors:',['Biomass =' num2str(Basisdaten.Primaerenergiefaktor.Biomasse.today)], ...
      ['Electricity =' num2str(Basisdaten.Primaerenergiefaktor.Strom.today)]};

It is happening because its creating seprate cells.

you can modify like below :

txt = {'Primary energy factors:','Biomass = ' ,num2str(11), ...
        'Electricity = ' num2str(12),};
display(txt)

txt = 1×5 cell array
    {'Primary energy factors:'}    {'Biomass = '}    {'11'}    {'Electricity = '}    {'12'}

txt = {'Primary energy factors:',['Biomass = ' ,num2str(11)], ...
        ['Electricity = ', num2str(12)],};
display(txt)

txt = 1×3 cell array
    {'Primary energy factors:'}    {'Biomass = 11'}    {'Electricity = 12'}

figure()
    xlabel('Primary Energy Demand');
    txt = {'Primary energy factors:',['Biomass = ' ,num2str(11)], ...
        ['Electricity = ', num2str(12)],};
    dim = [.15 .6 .3 .3];
    annotation('textbox',dim,'String',txt,'FitBoxToText','on');
