StatisticCanvasVisualizer

simple module

This module visualizes statistics on a 2D canvas. See the base module for how to configure which statistic is displayed. If configured properly, then it displays the last value of the statistic to the right of the visualization of the corresponding network node. The value and the unit is wrapped in a filled white rectangle.

Extends

Name	Type	Description
StatisticVisualizerBase	simple module	This is a base module for statistic visualizer simple modules. It keeps track of the last value of a statistic for multiple network nodes. The actual visualization of statistic values is done in derived modules. It subscribes for the signal determined by the signalName parameter at the module specified by the subscriptionModule parameter. If the visualizer receives such a signal it checks if the source matches the sourceFilter parameter. If the signal passes the check it determines the last value of the statistic specified by the statisticName parameter.

Parameters

Name	Type	Default value	Description
visualizerTargetModule	string	""	module path relative to the visualizer where the visualization should appear in the user interface, root module by default
tags	string	""	tag added to each visualization for disambiguation in the runtime environment
networkNodeVisualizerModule	string	"^.networkNodeVisualizer"	the network node visualizer module, refers to a sibling submodule by default
subscriptionModule	string	""	module where the visualizer subscribes for the signal, root module by default
displayStatistics	bool	true
signalName	string	""	signal name to subscribe, no signal name by default
statisticName	string	signalName	statistic name to get the value, signal name by default
statisticUnit	string	""	statistic unit, undefined by default
sourceFilter	string	"**"	pattern that must match the signal source, no source filter by default
format	string	"%n: %v %u"	determines what is displayed, info by default
unit	string	""	display the value in this unit, statistic unit by default
font	string	""	statistic value font, automatic by default
textColor	string	"black"	statistic value font color, black by default
backgroundColor	string	"white"	statistic value background color, white by default
opacity	double	1.0	opacity of the visualization
placementHint	string	"top"	annotation placement hint, space separated list of any, top, bottom, left, right, topLeft, topCenter, topRight, etc.
placementPriority	double	0	determines the order of annotation positioning
zIndex	double	10	determines the drawing order of figures relative to other visualizers
