Hi! I have a question regarding labelling points in matlab. I have a figure which needs to be labelled based on the data in the table. I read the example of labelling, but it mostly label based on the number of the points, not the data itself. I attach the picture of the figure and their corresponding label. The 'sampling point' should be labelled based on the data in LabelSamplPoint in cell 16 (I attach the picture of the table). I am confused about how to put the data in cell 16 as the label to the points in the plot. The point itself is from cell 15 for y-axis and the x-axis is cell 1. Could you please help me? Thank you very much for your help.

mask = ~isnan(finalCSVnew.LabelSamplPoint);
xvals = finalCSVnew{mask, 1}; %assuming you are right
yvals = finalCSVnew{mask, 15}; %are you sure?? This appears to be SamplError not a y value
labvals = FinalCSVnew.LabelSamplPoint(mask);
text(xvals, yvals, labvals)

labvals = sprintfc('%g', finalCSVnew.LabelSamplPoint(mask));
