I converted the boxplot color to black. So i want to distinguish median with different pattern. I tried giving notch option to boxplot. But that does not look nice. Is there any way to represent median in dotted lines?? or any other nice representation???

Can you please show an example, because the color of the median line defaults to red. So I don't think I understand what you're saying. At any rate, you can modify that line like this:

load carsmall;
boxplot(MPG)
h = findobj(gca,'tag','Median');
set(h,'linestyle','-.');
set(h,'Color',[0 0 0])

As an example,

 figure
h = boxplot(abs((t_base)-(t_60min)),'notch','on','sym','k*',   'colors','k');title('Base 60min')
set(h,{'linew'},{2})

Here when the color black is chosen for whole boxplot, then the median is not distinguished. So i enabled notch to 'on'. So that the median is distinguish with sharp edges. But when there is a case the 25th percentile and the median are same, then the median looks like horns. As an example i am attaching the image link below

The example you gave is working. But still when the median and 25th percentile are same, we can not distinguish the median.
