| | | | | | | | Magnetometer chart changed from polar chart view to chart view. Also changed the series to LineSeries. Change-Id: Ibdf2dc1c86e63fd20caa8d3c1a09377ea6de8f4b Reviewed-by: Otto Ryynänen <otto.ryynanen@qt.io>
* Move series updates to C++Maurice Kalinowski2017-02-161-0/+191
Instead of jumping to and from the QML engine for each sensor update, rather stay inside C++ and let QML only do the visual updates. This only updates the items which use Charts, as updates to a series is expensive. Change-Id: Idc7a98d2865e7095264f226c0ac5bbb5a977d18a Reviewed-by: Titta Heikkala <titta.heikkala@qt.io>
