The example shows - how to: - - \list - \li Create an application with Q3DScatter and some widgets - \li Use QScatterDataProxy to set data to the graph - \li Adjust some graph properties using widget controls - \endlist - - For instructions about how to interact with the graph, see \l{Qt Data Visualization Interacting with Data}{this page}. - - \image scatter-example.png - - \include examples-run.qdocinc - - \section1 Creating the Application - - First, in main.cpp, we create a QApplication, instantiate Q3DScatter, and a window container - for it: - - \snippet scatter/main.cpp 0 - - The call to QWidget::createWindowContainer is required, as all data visualization graph classes - (Q3DBars, Q3DScatter, and Q3DSurface) inherit QWindow. Any class inheriting QWindow cannot be used - as a widget any other way. - - Then we'll create horizontal and vertical layouts. We'll add the graph and the vertical - layout into the horizontal one: - - \snippet scatter/main.cpp 1 - - We're not using the vertical layout for anything yet, but we'll get back to it in - \l {Using widgets to control the graph} - - Next, let's create another class to handle the data addition and other interaction with the - graph. Let's call it \c ScatterDataModifier (See \l {Setting up the graph} and - \l {Adding data to the graph} for details): - - \snippet scatter/main.cpp 2 - - The application main is done. We can show the graph and start the event loop: - - \snippet scatter/main.cpp 3 - - \section1 Setting up the Graph - - Let's set up some visual qualities for the graph in the constructor of the \c ScatterDataModifier - class we instantiated in the application main: - - \snippet scatter/scatterdatamodifier.cpp 0 - - None of these are required, but are used to override graph defaults. You can try how it looks - with the preset defaults by commenting the block above out. - - Finally we create a QScatterDataProxy and the associated QScatter3DSeries. We set custom label format - and mesh smoothing for the series and add it to the graph: - - \snippet scatter/scatterdatamodifier.cpp 2 - - That concludes setting up the graph. - - \section1 Adding Data to the Graph - - The last thing we do in the \c ScatterDataModifier constructor is to add data to the graph: - - \snippet scatter/scatterdatamodifier.cpp 3 - - The actual data addition is done in \c addData() method. First we configure the axes: - - \snippet scatter/scatterdatamodifier.cpp 4 - - This could have been done in the constructor of \c {ScatterDataModifier}, but we added it here - to keep the constructor simpler and the axes configuration near the data. - - Next we create a data array: - - \snippet scatter/scatterdatamodifier.cpp 5 - - and populate it: - - \snippet scatter/scatterdatamodifier.cpp 6 - - Finally we tell the proxy to start using the data we gave it: - - \snippet scatter/scatterdatamodifier.cpp 7 - - Now our graph has the data and is ready to be used. There isn't much interaction yet, though, - so let's continue by adding some widgets to play with. - - \section1 Using Widgets to Control the Graph - - First, back in the application main, we'll create some widgets: - - \snippet scatter/main.cpp 4 - - And add them to the vertical layout we created earlier: - - \snippet scatter/main.cpp 5 - - Now, let's connect them to methods in ScatterDataModifier: - - \snippet scatter/main.cpp 6 - - Here are the methods in ScatterDataModifier the signals were connected to: - - \snippet scatter/scatterdatamodifier.cpp 8 - - And so we have an application in which we can control: - - \list - \li Label style - \li Camera preset - \li Background visibility - \li Grid visibility - \li Dot shading smoothness - \li Dot style - \li Theme - \li Shadow quality - \li Label font - \endlist - - \section1 Example Contents -*/ |
