Detailed Description

Plotting various data in a single widget.

Author: Jan Benda

Bug:

autoscale with zero interval

check initTics algorithmns. Make them iterative!

Todo:

execute init* routines immediately in draw(), only draw* routines should be posted.

logarithmic axis

add axis as an own plot object in addition to border

more colors and gradients (index is index to either a color, a gradient? or a picture!

matrix plot (contour colors)

create an update command to redraw shifted data.

Constructor & Destructor Documentation

Plot	(	KeepMode	keep,
		QWidget *	parent = `0`
	)

Constructs a plot with KeepMode keep. If you set keep to Plot::Pointer and you are using multible threads, then you need to provide a mutex for locking the data via setDataMutex().

Plot ( QWidget * parent = 0 )

References Plot::Copy.

Plot	(	KeepMode	keep,
		bool	subwidget,
		int	id = `0`,
		MultiPlot *	mp = `0`

bool tryLock ( int timeoutms = 1 )

Try to lock the plot mutex for at maximum timeoutms milliseconds.

void unlock ( void )

Unlock the plot mutex.

void setDataMutex ( QMutex * mutex )

Provide a mutex that is used by Plot to lock access to data while they are plotted. If you want to change the mutex, you first have to disable the mutex by calling clearDataMutex().

See Also: setDataMutex(QReadWriteLock*), lockData()

void setDataMutex ( QReadWriteLock * mutex )

Provide a mutex that is used by Plot to lock reading access to data while they are plotted. If you want to change the mutex, you first have to disable the mutex by calling clearDataMutex().

See Also: setDataMutex(QMutex*), lockData()

void clearDataMutex ( void )

Disables the data mutex.

See Also: setDataMutex()

void lockData ( void )

Lock the data mutex if it was set by setDataMutex() before.

See Also: tryLockData(), unlockData()

bool tryLockData ( int timeout = 1 )

Try to lock the data mutex for reading. Returns true if the lock was obtained within timeout milliseconds.

See Also: lockData(), setDataMutex(), clearDataMutex()

bool equalDataMutex ( const Plot & p ) const

Returns true if this has the same data mutex as p.

See Also: setDataMutex()

bool noDataMutex ( void ) const

Returns true if no data mutex is set.
