class TaurusTrend2DDialog(parent=None, designMode=False, toolbar=True, stackMode='deltatime', buffersize=512, options=None, autoscale='xyz', **kwargs)[source]

Bases: guiqwt.plot.ImageDialog, taurus.qt.qtgui.base.taurusbase.TaurusBaseWidget

This is a widget for displaying trends from 1D Taurus attributes (i.e., representing the variation over time of a 1D array). Sometimes this kind of plots are also known as “spectrograms”.

The widget shows a 3D plot (Z represented with colors) where the values in the 1D array are plotted in the Y-Z plane and are stacked along the X axis.

getMaxDataBufferSize()[source]

returns the maximum number of events that can be plotted in the trend

Return type:int
Returns:
getModel()[source]

reimplemented from TaurusBaseWidget

getModelClass()[source]

classmethod getQtDesignerPluginInfo()[source]

reimplemented from TaurusBaseWidget

getStackMode()[source]
getUseArchiving()[source]

whether TaurusTrend is looking for data in the archiver when needed

Return type:bool
Returns:
keyPressEvent(event)[source]
maxDataBufferSize

returns the maximum number of events that can be plotted in the trend

Return type:int
Returns:
model

reimplemented from TaurusBaseWidget

modifiableByUser

whether the user can change the contents of the widget

Return type:bool
Returns:True if the user is allowed to modify the look&feel
resetMaxDataBufferSize()[source]

Same as setMaxDataBufferSize(512) (i.e. 512 events)

resetStackMode()[source]
resetUseArchiving()[source]

Same as setUseArchiving(False)

setModel(model)[source]

reimplemented from TaurusBaseWidget

setModifiableByUser(modifiable)[source]

reimplemented from TaurusBaseWidget

setStackMode(mode)[source]

set the type of stack to be used. This determines how X values are interpreted:

  • as timestamps (‘datetime’)
  • as time deltas (‘timedelta’)
  • as event numbers (‘event’)
Parameters:mode (one of 'datetime', 'timedelta' or 'event') –
setUseArchiving(enable)[source]

enables/disables looking up in the archiver for data stored before the Trend was started

Parameters:enable (bool) – if True, archiving values will be used if available
stackMode
useArchiving

whether TaurusTrend is looking for data in the archiver when needed

Return type:bool
Returns:
