It requires building PySide6 with the ``--pyside-numpy-support`` +option. This example demonstrates the following features: + +* How to set up a QSurfaceDataProxy from a 2-dimensional numpy array. +* How to use QHeightMapSurfaceDataProxy for showing 3D height maps. +* Three different selection modes for studying the graph. +* Axis range usage for displaying selected portions of the graph. +* Changing theme. +* How to set a custom surface gradient. + +For instructions about how to interact with the graph, see `this page`_. + +.. image:: surface_mountain.png + :width: 400 + :alt: Surface Example Screenshot + +.. _`this page`: https://doc.qt.io/qt-6/qtdatavisualization-interacting-with-data.html |
