推荐答案

选项1:升级

我想您的意思是插入QChartView，因为QChartView继承自QGraphicsView，所以这是一个不错的选择，为此，我们执行以下操作:

Option 1: Promoted

I suppose you mean inserting a QChartView, because QChartView inherits from QGraphicsView, this would be a good option, for this we do the following:

1. 首先在.pro
中添加QT += charts
2. 将QGraphicsView放置到设计中.
3. 右键单击QGraphicsView并选择Promote to...
4. 执行上述操作时，将出现一个菜单，该菜单应在Promoted Class Name的QChartView和Header file的QtCharts中进行设置，然后按add按钮，最后按promote

1. first add QT += charts in the .pro
2. place the QGraphicsView to the design.
3. Right click on the QGraphicsView and select Promote to...
4. When doing the above, a menu appears, in the menu it should be set in QChartView in Promoted Class Name, and QtCharts in Header file, then press the add button and finally press promote.

使用QWidget作为基础而不是QGraphicsView，可以完成相同的操作.

The same could be done using QWidget as a base instead of QGraphicsView.

为什么选择一个或另一个小部件作为基础?

之所以选择它，是因为Qt Designer通过moc在默认情况下会建立某些属性，并且如果窗口小部件不具有该方法，则它将无法编译.由于所有小部件都从QWidget继承而来，因此这将成为任何新的小部件在Qt Designer中对其进行推广的基础.

It is chosen because Qt Designer through moc establishes certain properties by default, and if the widget does not have that method then it will not compile. as all widgets inherit from QWidget this would be the basis for any new widget to promote it in Qt Designer.

另一种选择是为QtDesigner编译QtChart插件，因为它必须从以下

Another option would be to compile the QtChart plugin for QtDesigner, for it you must download the 5 files from the following link:

然后执行以下操作:

qmake
make
sudo make install

最后，您可以在Qt Designer中访问QtCharts::QChartView

At the end you can access QtCharts::QChartView in Qt Designer
