Plots in Matlab using Latex interpreter

Hi

I want to insert a bar over a parameter in xlabel of plot for representing it as an average value. I have used Latex interpreter for this using command:

xlabel('Average throughput $\it{\bar{T}} \rm{(files/slot)}$','interpreter','latex');

set(get(gca,'XLabel'),'Fontname','Times new roman','FontSize',14);

When i excute the command, it doesn't change the font type to Times new roman rather a different font is displayed. Only the font size changes. I think the problem is with \bar{T}. I have changed to Tex and removed $ signs as well then it shows the same text as shown in xlabel.

I will be oblidged if someone could give me suggestion.

When you use $$ then that is Math mode, which uses a different font by default. To control the font inside Math mode, you need to embed font commands. See https://www.mathworks.com/matlabcentral/answers/321122-how-to-change-the-fontname-of-axes-labels-when-using-the-latex-interpreter#answer_251215

Dear Walter,

I got a similar issue but my code, does not give me an error or anything else. I have found the interpreter function for making more appealling the text which I am introducing to my pie chart, but it is not working properly.

Can you help me with any workaround to overcome the issue highlithed in the figure that I have shared.

I look forward to hearing from you

Best regards

    x=[Gas, Petrol, PV_siliceLCA];
    explode=[0 1 0];
    p=pie(x, explode);
  
    pText = findobj(p,'Type','text');
    percentValues = get(pText,'String');
    txt = {'Gas_m^3: ';'Petrol_Lts: '; 'PV_W·h: '};
    combinedtxt = strcat(txt,percentValues);
 
    pText(1).String = combinedtxt(1);
    pText(2).String = combinedtxt(2);
    pText(3).String = combinedtxt(3);
