Plot local maxima of a scalogram

Hello every body, 
I am asking your kindness to help me to plot the local maxima of a
scalogram 
(computed with the Discrete wavelet Transform). Indeed, I find the local 
maxima of the scalogram by considering the localmax matlab function but I

can't plot the obtained result as a significant figure that allows me to 
interpret the signal singularities. 

Best regards.
