Added a property to restore the old zoom behavior. +- Added properties to control the minimum and maximum allowable zoom level of the camera. +- Added a method for getting the list of custom items added to the graph. +- Added a property for specifying the graph background margin. + +Fixed issues +------------ + +General: +- Label widths now update consistently when axis range changes. +- Made selection texture creation more robust. +- Grid lines and labels no longer change size if aspect ratio changes. +- Q3DTheme::ColorStyleObjectGradient now works for surface graphs. +- Removed the superfluous common.pri. +- Fixed non-visible selected object drawing in static optimization mode. +- Gradient color styles are now supported equally in both default and static optimization modes. +- Specular highlight now works with rotated objects in static optimization mode. +- Fixed a crash in static optimization mode when data is updated without resizing. +- Fixed changing items in static optimization mode. +- Fixed issues with static optimization mode when some items were outside axis ranges. +- Slice mode grid lines should no longer vanish into the background when using high ambient light + value. +- Reduced the size of the surface selection texture, allowing selection to work with larger + surfaces. +- Fixed QAbstract3DGraph::renderToImage in OpenGL ES2 environments. +- Fixed crash when attempting to enable slicing without row/column selection modes. +- QCustom3DLabels now use the same shader as other labels, which means the specular highlight + no longer makes camera facing custom labels unreadable with some themes. +- Made various selection queries thread safe. +- Fixed selection query synchronization issue when using threaded renderer. +- Font size is automatically reduced if the label gets too wide to fit the label texture. +- Fixed the ordering of the subviews. +- Fixed surface normals in cases where the surface values were not in the same order + (ascending or descending) along both axes. +- Fixed a crash when removing and changing items on the same render frame. +- Fixed an issue with grid line color on surface graphs. +- Prevented selecting bars through the floor in bar graphs. +- Fixed recurring GL_INVALID_VALUE OpenGL errors. +- Improved the surface shadows. +- Fixed the OpenGL context cleanup upon renderer destruction. +- Fixed scatter item autosizing when adding a new series. +- Fixed a crash related to selection render buffer reuse. +- Fixed the flipped Z-coordinate for absolutely positioned custom items. +- Fixed shadows when viewing the graph directly from above or below. + +New examples +------------ + +- Qmlspectrogram example added. It shows how to display 2D spectrogram using surface graph with + gradients and orthographic projection. Also demonstrates the use of polar axes. +- Bars example now demonstrates zooming to selection, which leverages the new ability to + control the camera target. +- Textured surface example added. +- Volumetric example added. It shows how to use the new QCustom3DVolume object to visualize + volumetric data. +- Reflection added to Bars and Customproxy examples. +- Custom camera targeting added to Bars example. |
