Thanks for your help!
I know how to make a bedgraph file, but it's just that I thought galaxy
could automatically make a bedgraph file ( or track ) out from a text file.
Maybe I was thinking wrong.

I think you need to include a track line and specify "bedgraph", like this
Is that maybe the problem? It sounds like UCSC is treating your file as a
standard "bed", which it will do without the track line.

dataset). Confirm that this database is at UCSC by matching the database
short name "dbkey" with that used in Galaxy. If the database is not at UCSC,
then Visualization within Galaxy is still an option (Trackster).

explicitly labeled as being a data value for display, but that does not
impact display. Not all values for all datatypes are labeled the same as
external sites do, yet many display correctly based on the file format type

track for UCSC genome browser". This is not necessary, but does allow for
some user-defined labels. For full control over the track and (again,
optional) browser lines used by UCSC, create this information in a text file
on your computer, save, load into Galaxy, and merge with the bedgraph data
using "Text Manipulation -> Concatenate datasets tail-to-head".

server at http://usegalaxy.org, please send a shared history link and I can
take a look and provide feedback ("Options -> Share or Publish, generate
link, and email back directly to me). But, hopefully the above helps to
resolve anything that was unclear. I just tested a bedgraph a few minutes
ago, to confirm that there were no issue between Galaxy & UCSC for a sample
bedgraph dataset, and it worked fine.
