New TRestMetadataPlot class has been added to the framework. It is used in a very similar way to the TRestAnalysisPlot class, but it is used to create graphs with points extracted from metadata members.
We can assign to a <plot any metadata member as an xVariable, and each graph inside the plot will be associated to a corresponding yVariable.
We can access any metadata member from any metadata class that it is accessible to TRestRun.
Simply specifying the format TRestMetadataClass->fDataMember.
An example has been also uploaded to the repository: examples/metadataPlot.rml.
Using TREX-DM data the example file generates the following evolution plot with the data found inside the class TRestSummaryProcess from thousands of files of data.
