How to insert both value and percentage in pie chart?

Dear all,

I just want to know how to insert in the same pie chart the values that comprise the already presented percentage?

This is the code

      figure
      xe=[5, 20, 15];
      explode=[ 1 0 1];
      pe=pie(xe, explode);
    
        %%%% tagging 
        pText = findobj(pe,'Type','text');
        percentValues = get(pText,'String');
        txt = {'Geothermal: '; 'PV: '; 'EVs: '};
        combinedtxt = strcat(txt,percentValues);
        %%%%Set text
        pText(1).String = combinedtxt(1);
        pText(2).String = combinedtxt(2);
        pText(3).String = combinedtxt(3);

That's another terrible user interface/oversight to go along with bar -- hadn't ever used it in MATLAB before; pie charts just are a format I used rarely, if ever...anyways, that aside you've got to build them yourselves it seems, but isn't too difficult, just annoying--

labels=compose('%s: %d (%0.1f%%)',string(txt),xe(:),100*xe(:)/sum(xe));
hP=pie(xe,explode,labels)

works -- you might want to try

labels=compose('%s: %d \n(%0.1f%%)',string(txt),xe(:),100*xe(:)/sum(xe));

and 'spearmint about alternate formatting.

NB: You'll have better luck and the above assumes the trailing ":" and blanks have been removed from the variable names/section names.
