class
TaurusTrendDialog
(parent=None, designMode=False, taurusparam=None, toolbar=True, **kwargs)[source]¶ Bases:
guiqwt.plot.CurveDialog
,taurus.qt.qtgui.base.taurusbase.TaurusBaseWidget
A taurus widget for showing trends of scalar data. It is an specialization of
guiqwt.plot.CurveWidget
, for displaying trends and offering the expected Taurus interface (e.g. setting models, save/apply configs, drag&drops,…)See also
-
addModels
(modelNames)[source]¶ Creates TaurusCurveItems (one for each model in modelNames) and attaches them to the plot.
Note
you can also add curves using
add_items()
.addModels()
is only a more Taurus-oriented interface.add_items()
gives you more control.Parameters: modelNames ( sequence
<str
> orstr
) – the names of the models to be plotted. For convenience, a string is also accepted (instead of a sequence of strings), in which case the string will be internally converted to a sequence by splitting it on whitespace and commas.See also
add_item()
-
getMaxDataBufferSize
()[source]¶ returns the maximum number of events that can be plotted in the trend
Return type: int
Returns:
-
getUseArchiving
()[source]¶ whether TaurusTrend is looking for data in the archiver when needed
Return type: bool
Returns: See also
-
maxDataBufferSize
¶ returns the maximum number of events that can be plotted in the trend
Return type: int
Returns:
-
model
¶ reimplemented from
TaurusBaseWidget
-
modelChanged
¶
-
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
-
setMaxDataBufferSize
(maxSize)[source]¶ sets the maximum number of events that will be stacked
Parameters: maxSize ( int
) – the maximum limitSee also
TaurusTrendSet
-
setModel
(modelNames)[source]¶ Removes current TaurusCurveItems and adds new ones.
Parameters: modelNames ( sequence
<str
> orstr
) – the names of the models to be plotted. For convenience, a string is also accepted (instead of a sequence of strings), in which case the string will be internally converted to a sequence by splitting it on whitespace and commas.See also
-
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: See also
