Perfect! thats what i wanted to know. thanks!

Hi Andy,

Thanks for your quick reply. I see that i have to use the yoda 2d scatter plot for such plots. I can do that sure.

Regarding the .cc file, let me clarify a bit. I have my own analysis that ive written in rivet lets call it MYANA.cc<http://myana.cc/>. Now this MYANA.cc<http://myana.cc/> has the same plots that the atlas conf note has (except these in my analysis they are histograms and from the note they are ) so i wanted to know if i can just compare it like this
rivet-mkhtml myana_output.yoda ATLAS-CONF-2012-119.yoda
where the latter yoda file ive filled it by hand like we mentioned before. I was asking if i should create a separate ATLAS-CONF-2012-119.cc<http://atlas-conf-2012-119.cc/> to produce the plots in rivet? (for some required reason, im not sure)

The name of the analysis doesn't really matter -- all you need to make sure is that the histogram path names that you use in your analysis match up with the ones in your hand-coded reference .yoda file.

In rivet-cmphistos (which is called by rivet-mkhtml), the histograms (e.g. Histo1Ds) written out of your analysis are converted to Scatter2Ds for the plotted comparison.

Hi Raghav,

The YODA and AIDA formats both discriminate between "histograms" and similar which have number-of-entries, sums of weights, etc., and "graph/scatter/datapoint-set" objects which are just list of x & y points and their errors. Reference data all has to use the latter sort, since the details of the histogram filling aren't recorded.

If you take a look at some of the .yoda reference data files that come bundled with Rivet, you'll see the syntax for the YODA Scatter2D type, which is the relevant thing to use. It's fine to enter the values from a plot grabber, although obviously there are better ways for "official" analysis submissions from the experiments because they have the original data files available.

Regarding writing the .cc analysis code, yes you will need to do this. We need a more specific question, though! There are some tutorials linked from the Rivet website via the "Documentation" link, as well as a quick guide under "Writing an analysis". Let us know if you need help with some aspect in particular.

Cheers,
Andy

I think I know how to do it using the old rivet and an aida file. But
with this yoda file now contains the scale, total entires etc... which
we cant get from the data plot.

Dear Rivet experts,

Im not sure if this is the right place to ask questions, but I would
like to use the data points from the ATLAS conference note
ATLAS-CONF-2012-119
<http://cds.cern.ch/record/1472941/files/ATLAS-CONF-2012-119.pdf> with
the latest version of rivet. I was thinking that I just create a .yoda
file and hand write in all the values i get off a plot grabber. Should
i also create a .cc analysis with this? im not sure how this is done.
thanks!

Cheers
Raghav
