Detailed Description

Easy to use widget component for 2D data visualization.

In contrast to it's parent class icl::LowLevelPlotWidget, the icl::PlotWidget interface is allinged with ICL's 2D image annotation framework (see icl::ICLDrawWidget).

Visualization Types

The PlotWidget has two types of content:

Plotting Data (visualized as scatter-plot: PlotWidget::scatter, or series/function plot: PlotWidget::series, or bar-plot: PlotWidget::bars)
Annotation data these are extra primitives that are used to show/highligh additional information in the data plot. Annotations are always drawn in the data coordinate space.

Only plotting data is used for automatic view-port estimation.

General Information

The PlotWidget internally uses a synchronized queue of darw commands. Draw commands can only added in a thread-safe manner if the PlotWidget is locked (see PlotWidget::lock() and PlotWidget::unlock() ). The PlotWidget does not support to reference to be visualized data using a shallow/pointer copy. Instead, the given data is always copied deeply into an internal buffer. By theses means, given data must not be kept in memory or synchronized mannually. While locked, the following operations for data visualization are available:

PlotWidget::clear() clears the former draw command queue
PlotWidget::label and PlotWidget::nolabel set/unset the legend label for the next scatter, series or bar plot
PlotWidget::color sets the drawing color. This is usually used for symbols as well as for any lines for drawing data as well as for annotations.
PlotWidget::pen also affects the drawing color, but it can be used to a custom pen for line drawing. The pen can e.g. be set up to draw dashed lines.
PlotWidget::linewidth does also affect the pen, so using PlotWidget::pen, will also overwrite the last linewidth value.
PlotWidget::fill is used to the the color for filled areas, such as the bars in a bar-plot, or area between the function-graph and the y=0 axis in series plots. It also affects the fill color of rect- and ellipse annotations.
PlotWidget::brush is similar to fill as pen to color. By setting a QBrush, special color patterns can be used for filling.
PlotWidget::sym sets the symbol, that is used for scatter and series plots. Supported symbols are listed in the documentation of the AbstractPlotWidget::Pen::Pen constructor.
PlotWidget::scatter, PlotWidget::series and PlotWidget::bars are used to pass Plotting data that is then visualized. For each of these functions, that are several convenience methods and even template that allow for passing differently shaped data directly.

For annotation data, the following basic methods are provided. Again, for each of these, several convience methods are also available.

PlotWidget::line draws a line (using the current color)
PlotWidget::rect draws a rect (using the current color and fill)
PlotWidget::circle draws a circle (using the current color and fill)
PlotWidget::text draws text into the drawing area (using the currnet color)
PlotWidget::linestrip draws several lines each starting where the last line ended. In this case, only N-1 points have to be passed for N lines
PlotWidget::grid allows to draw a 2D grid annotation

The methods, PlotWidget::title, PlotWidget::xlabel and PlotWidget::ylabel are just convenience function that use the derived Configurable's Configurable::setPropertyValue method in a direct manner.

void icl::qt::PlotWidget::scatter	(	const math::FixedMatrix< T, 2, 1 > *	ps,
		int	num,
		bool	connect = `false`
	)

inline

◆ scatter() [6/6]

void icl::qt::PlotWidget::scatter	(	const std::vector< math::FixedColVector< float, 2 > > &	ps,
		bool	connect = `false`
	)

inline

adds a scatter plot from given vector of fixed vectors

◆ series() [1/2]

template<class T >

ICLQt_API void icl::qt::PlotWidget::series	(	const T *	data,
		int	num,
		int	stride = `1`
	)

adds series data

Parameters

data	data pointer
num	number of elements
stride	data increment to iterate through the data elements stride is given in sizeof(float) units

◆ series() [2/2]

template<class T >

void icl::qt::PlotWidget::series ( const std::vector< T > & data )

inline

adds series data from given std::vector

◆ sym() [1/2]

void icl::qt::PlotWidget::sym ( char s )

sets the current symbol

The symbol is used for series and scatter plots

◆ sym() [2/2]

void icl::qt::PlotWidget::sym	(	char	s,
		int	symsize
	)

inline

sets the current symbol and the symbol size

The symbol size is always given in pixels

◆ symsize()

void icl::qt::PlotWidget::symsize ( float size )

sets the symbols size

◆ text() [1/2]

void icl::qt::PlotWidget::text	(	float	x,
		float	y,
		const std::string &	text
	)

draws a text annotation

Note.: the text anchor is always centered)

◆ text() [2/2]

void icl::qt::PlotWidget::text	(	const utils::Point32f &	p,
		const std::string &	text
	)

draws a text annotation

Note.: the text anchor is always centered)

◆ title()

void icl::qt::PlotWidget::title ( const std::string & title )

inline

sets the diagram title

Please note, that usually the property "borders.top" needs to be set to something around 18. Otherwise, the tiltle is placed within the drawing area

◆ unlock()

void icl::qt::PlotWidget::unlock ( )

inline

unlocks the draw queue

◆ xlabel()

void icl::qt::PlotWidget::xlabel ( const std::string & xlabel )

inline

sets the x-axis label

◆ ylabel()

void icl::qt::PlotWidget::ylabel ( const std::string & ylabel )

inline

sets the y-axis label
