Ok, in the interim, my manual workaround is: - scan each dataset column - if any column is completely 0, then insert a single 1 as the first data point
By using either the first or last data point, I have found that the visualization tends to hide the incorrect data at most zoom levels, while rendering all other data points correctly. It's a fairly big hack, though, and iterates through all data at a large cost. -- Darien On Jun 8, 4:48 am, VizGuy <[email protected]> wrote: > Thanks for reporting this issue.We will look into it and see what can be > done. > > I have no quick workaround though. > > Regards, > VizGuy > > On Mon, Jun 1, 2009 at 8:09 PM, dkindlund <[email protected]> wrote: > > > It's best I explain this by example, using the pens code as a basis > > from the AJAX API.
