chainmap_t

typedef std::map<std::string,std::string> chainmap_t

global typedef here is ok, since this is a standalone executable, including a main().

As such it does not need to be in a namespace at this point as it won't in any case be visible outside this translation unit

main()

int main	(	int	argc,
		char **	argv
	)

control stuff

control flags and labels

leave this commented here - now instead of bombing out if we don't specify the reference file, just carry on as if it was not specified at all, so as this changes the external behaviour of the code we want this retained

don't fail anymore if can't open the reference file, now continue without plotting the refereces, instead printing a warning on the plots

get release data

we divide the resolutions by these values if we have an "entries" histogram to tell us how many events there are overall

get from Chains?

set up the correct reference chain names ...

get the actual chain name and track collection from

the Chain histogram if present

reference chains

set up the plot panels

read config in from a file if requested ...

read the histos - 1 panel per histo

read in the panel descriptions

use the default values as single histogram panels

use the default panels

a better colour palette than the egregious root default

Fixme: add the 2D histogram processing here ??

words can not express the sheer unpleasantness in trying to do anything serious with subpanels

• if any margins between pads are set to 0, root messes up the pad margins so they are 0 with seemingly no way to prevent it - have to use a very small (but non 0) value, but then the margins don't size properly.
• Once you cd() to one of the child pads, if you ask for the child GetWh() or GetWw() you don't get the parameters of the child pad, but the main pad etc

How are you supposed to get the paremeters of the actual pad ? It is insane.

histos within the panel

leave this code commented here for the time being ... if ( histo.name()=="pT" || histo.name()=="pT_rec" ) ypos = 0.19;

calculate all the postions for the items in the legend

legends ....

leave these comments here for testing ...

get the actual chain name and track collection from the Chain histogram if present

refit the resplots - get the 2d histogram and refit

get the test histogram

Actually DO refit the references - if we are adding together many resplots, then the means etc may not even have been calculated

leave this code commented here since we want to know where to change this in the future it was added for a reason, so is useful to keep for now

useful test for debugging ...

everything else

leave this code commented here since we want to know where to change this in the future it was added for a reason, so useful to keep for now

debugging ...

rebin if requested ...

now recalculate reference

leave for documentation purposes ...

again, this changes the external behaviour so we want to leave this "continue" in place, but commented

only set the plot name once )

replace the "/" in the filename so we don't try to make plots in subdirectories by accident

calculate and set axis limits

resolutions

calculate power

try to localise all axis range setting, log, lin scales etc to this one place

sort out the range settings for the xaxis ...

calculate the log range

keep the original equation by way of documentation ...

leave this code commented here since we want to know where to change this in the future it was added for a reason, so it is useful to keep for now
std::exit(-1);

calculate the required range such that the histogram labels won't crowd the points

actually draw the plot here ...

loop over histograms in panel

NB: now, we no longer print the individual plots - only the "panels" individual plots can still be printed by creating a "panel" which contains only that plots - in fast the "histos" item that before provided details of the separate plots is now interpreted as a list of single plot panels so this is done for you

loop over panels

if deleting all non-used reference histograms

make sure we are not using the same reference as test file

clean up reference file

copy the release tree

debugging ...

close files

now actually overwrite the old reference file
