`TaurusTrendDialog`

class TaurusTrendDialog(parent=None, designMode=False, taurusparam=None, toolbar=True, **kwargs)[source]

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,…)

Import from taurus.qt.qtgui.extra_guiqwt as:

from taurus.qt.qtgui.extra_guiqwt import TaurusTrendDialog

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> or str) – 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.

Return type:: bool

resetMaxDataBufferSize()[source]: Same as setMaxDataBufferSize(16384)

TaurusTrendSet

setModel(modelNames, **kwargs)[source]

Removes current TaurusCurveItems and adds new ones.

Parameters:: modelNames (sequence<str> or str) – 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.

addModels()

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

Returns:
Return type:: bool
