[galaxy-user] Displaying bed files in ucsc

Hello, I have a bed file in this format: chr# start end scores. I tried to view it in ucsc main but it showed only where the fragments are(based on the start and end coordinates) with numerical scores beside each fragment. How do I view the file as a histogram format? What format will I need to convert the file to and where can I do the conversion? Any advise is greatly appreciated! Jose
