Hi,

I would like to plot a bargraph and add labels to the bars, showing a numerical value followed by the percentage symbol (%). Please find below a MWE:

x=table{:,"Xvalues"};
y=table{:,"Yvalues"};
barGraph=bar(x,y,0.9);
xtips1=barGraph(1).XEndPoints;
ytips1=barGraph(1).YEndPoints;
labels1=sprintfc('%.2f',table.labels);
text(xtips1,ytips1,labels1,'Rotation',45);

I know I can do that by defining 'labels1' as a string and then adding ' + '%' ' into the text command, as in:

x=table{:,"Xvalues"};
y=table{:,"Yvalues"};
barGraph=bar(x,y,0.9);
xtips1=barGraph(1).XEndPoints;
ytips1=barGraph(1).YEndPoints;
labels1=string(table.labels);
text(xtips1,ytips1,labels1 + '%','Rotation',45);

in this case, though, I cannot cut the values in 'labels1' after the second decimanl digit.

Thanks

We do not have your "table" variable and so cannot run the example. Also, "table" is inadvisable as a name for the varable, since it is also the name of a command.

Thanks for pointing this out, I used "table" as a variable only to show exactly how I had structured my code. I meant it to represent a generic table containing values. I wanted to make sure the error did not come from a wrong way of extracting the values. Sorry about it!
