Ptr< GnuplotAggregator > ns3::GnuplotHelper::GetAggregator ( )

Gets the aggregator.

Returns
Ptr to GnuplotAggregator object

This function is non-const because an aggregator may be lazily created by this method.

Gets the specified probe.

Parameters
probeNamethe probe's name.
Returns
Ptr to probe

◆ PlotProbe()

void ns3::GnuplotHelper::PlotProbe ( const std::string & typeId,
const std::string & path,
const std::string & probeTraceSource,
const std::string & title,
GnuplotAggregator::KeyLocation keyLocation = GnuplotAggregator::KEY_INSIDE )
Parameters
typeIdthe type ID for the probe used when it is created.
pathConfig path for underlying trace source to be probed
probeTraceSourcethe probe trace source to access.
titlethe title to be associated to this dataset
keyLocationthe location of the key in the plot.

Plots a dataset generated by hooking the ns-3 trace source with a probe, and then plot the values from the probeTraceSource. The dataset will have the provided title, and will consist of the 'newValue' at each timestamp.

This method will create one or more probes according to the TypeId provided, connect the probe(s) to the trace source specified by the config path, and hook the probeTraceSource(s) to the downstream aggregator.

If the config path has more than one match in the system (e.g. there is a wildcard), then one dataset for each match will be plotted. The dataset titles will be suffixed with the matched characters for each of the wildcards in the config path, separated by spaces. For example, if the proposed dataset title is the string "bytes", and there are two wildcards in the path, then dataset titles like "bytes-0 0" or "bytes-12 9" will be possible as labels for the datasets that are plotted.
