[Rivet] rivet-mkhtml problems

[Andy Buckley]

Hi Roy,

The plotting is falling over because it can't find the max(y-value) of 
the datasets when there are no datasets. Peering at the output and then 
looking in the .yoda file, the problem is probably these guys:

# BEGIN YODA_SCATTER2D /ATLAS_2012_I1083318/d02-x01-y01
Path=/ATLAS_2012_I1083318/d02-x01-y01
Title=
Type=Scatter2D
XLabel=
YLabel=
# xval	 xerr-	 xerr+	 yval	 yerr-	 yerr+
# END YODA_SCATTER2D

# BEGIN YODA_SCATTER2D /ATLAS_2012_I1083318/d02-x01-y02
Path=/ATLAS_2012_I1083318/d02-x01-y02
Title=
Type=Scatter2D
XLabel=
YLabel=
# xval	 xerr-	 xerr+	 yval	 yerr-	 yerr+
# END YODA_SCATTER2D

Note that these describe scatter plots with no points to plot -- any 
idea why you are getting those?

So it's understandable why the plotting is failing, but we should make 
it more robust: probably add some default behaviour that if there are no 
points and not explicitly requested {X,Y}{Min,Max} values, then make an 
empty plot in the 0..1, 0..1 range. I'll add that for the next Rivet 
release.

Andy

However the strange thing is that to produce each histogram 49, 48, 47 ... etc. I need to press return before the histogram is produced. If I do this until all histograms are plotted, the program exits correctly and I can view the histograms which look ok. However in this case I exited with Control-C.
