Bug ID: 359962
Summary: [wish] linear interpolation in Plotter (QtQuick item)
Product: frameworks-kdeclarative
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: wishlist
Priority: NOR
Component: general
Assignee: notm...@gmail.com
Reporter: lukas.schneiderba...@gmail.com
CC: kdelibs-b...@kde.org
The QtQuick item 'Plotter' (as for example used in the plasma-nm plasmoid)
always uses catmull-rom interpolation on any data it gets. This might not
always be the desired way of plotting the given data. Also, it can lead to poor
artefacts (for example on big steps of the y-values).
To remedy this, I suggest to add an option to choose linear interpolation
instead of Catmull-Rom interpolation.
The soon to be attached patch implements this by adding a Q_PROPERTY
"interpolation" to the Plotter-class, which allows the options
Interpolation.Linear and Interpolation.CatmullRom. The default is still
Interpolation.CatmullRom to avoid changing the behaviour of existing Plasmoids.
Reproducible: Always
