Member Function Documentation

void Plasma::SignalPlotter::addPlot ( const QColor & color )

Add a new line to the graph plotter, with the specified color.

Note that the order you add the plots must be the same order that the same data is given in (unless you reorder the plots).

Parameters

color the color to use for this plot

Definition at line 169 of file signalplotter.cpp.

void Plasma::SignalPlotter::addSample ( const QList< double > & samples )

Add data to the graph, and advance the graph by one time period.

The data must be given as a list in the same order that the plots were added (or consequently reordered).

Parameters

samples a list with the new value for each plot

Definition at line 182 of file signalplotter.cpp.

QColor Plasma::SignalPlotter::backgroundColor ( ) const

The color to set the background.

This might not be seen if an svg is also set.

Returns: the color of the plotter background

QFont Plasma::SignalPlotter::font ( ) const

The font used for the axis.

Returns: the font used to draw the text of the vertical values

QColor Plasma::SignalPlotter::fontColor ( ) const

The color of the font used for the axis.

Returns: the color used to draw the text of the vertical values

QPixmap Plasma::SignalPlotter::getSnapshotImage	(	uint	width,
		uint	height
	)

Render the graph to the specified width and height, and return it as an image.

This is useful, for example, if you draw a small version of the graph, but then want to show a large version in a tooltip etc

Parameters

width	the width of the snapshot
height	the height of the snapshot

Returns: a snapshot of the plotter as an image

Definition at line 571 of file signalplotter.cpp.

QColor Plasma::SignalPlotter::horizontalLinesColor ( ) const

The color of the horizontal grid lines.

Returns: the color used to draw the horizontal grid lines

uint Plasma::SignalPlotter::horizontalLinesCount ( ) const

The number of horizontal lines to draw.

Doesn't include the top most and bottom most lines.

Returns: the number of horizontal lines that will be drawn

uint Plasma::SignalPlotter::horizontalScale ( ) const

The number of pixels horizontally between data points.

Returns: the number of pixel drawn between two data points

double Plasma::SignalPlotter::lastValue ( uint i ) const

Return the last value that we have for plot i.

Returns 0 if not known.

Parameters
