Hi Deqiang, Here is a saved session that will show you that it is possible to display data with the value of 0.
http://genome.ucsc.edu/cgi-bin/hgTracks?hgS_doOtherUser=submit&hgS_otherUserName=Vanessa&hgS_otherUserSessionName=zero_wiggle You see that there is a line at 0 where the data has a value of 0. When you zoom out you see that when there is no data, there is no line. Here is the what was uploaded for this custom track example: track db=hg19 type=wiggle_0 priority='80' name='Wiggle bedGraph Format' description='wiggle bedGraph format thru zero' visibility=full color=200,100,0 altColor=0,100,200 chr21 33031597 33032705 -1.00 chr21 33032705 33033813 -0.75 chr21 33033813 33034921 -0.50 chr21 33034921 33036029 -0.25 chr21 33036029 33037137 0.00 chr21 33037137 33038245 0.25 chr21 33038245 33039353 0.50 chr21 33039353 33040461 0.75 chr21 33040461 33041569 1.00 track db=hg19 type=wiggle_0 priority='90' name='Wiggle bedGraph to zero' description='wiggle bedGraph format to zero' visibility=full color=200,100,0 altColor=0,100,200 chr21 33031597 33032705 -1.00 chr21 33032705 33033813 -0.75 chr21 33033813 33034921 -0.50 chr21 33034921 33036029 -0.25 chr21 33036029 33037137 0.00 chr21 33037137 33038245 -0.25 chr21 33038245 33039353 -0.50 chr21 33039353 33040461 -0.75 chr21 33040461 33041569 -1.00 track db=hg19 type=wiggle_0 priority='100' name='Wiggle bedGraph from zero' description='wiggle bedGraph format from zero' visibility=full color=200,100,0 altColor=0,100,200 chr21 33031597 33032705 1.00 chr21 33032705 33033813 0.75 chr21 33033813 33034921 0.50 chr21 33034921 33036029 0.25 chr21 33036029 33037137 0.00 chr21 33037137 33038245 0.25 chr21 33038245 33039353 0.50 chr21 33039353 33040461 0.75 chr21 33040461 33041569 1.00 Hopefully leads you in the right direction.

But I found that 0 can not be displayed. In that situation, I can not distinguish whether it is zero or no data. Any help is appreciated.
