将图形嵌入GUI（Qtdesigner和Pyside）

Question

我是堆叠溢出的新手。这是我的第一篇文章，所以如果我错了，请纠正我。将是准确的并解释我的问题。

我有一个记录，偏航和俯仰的传感器，记录的数据已根据项目要求进行处理和剪裁。我想嵌入在GUI中生成的图形。我正在使用Qt设计师和Pyside来做这件事。

我确实阅读了pyqtgraph文档并浏览了示例，文档并没有很好地掌握它。但是我按照步骤进行了操作，

“在Designer中，创建一个QGraphicsView小部件（”显示小部件“类别下的”图形视图“）。 右键单击QGraphicsView并选择“Promote To ...”。 在“已提升的班级名称”下，输入您要使用的班级名称（“PlotWidget”，“GraphicsLayoutWidget”等）。 在“标题文件”下，输入“pyqtgraph”。 点击“添加”，然后点击“推广”。“

现在如何处理图形视图小部件和pyqtgraph以在gui中绘制图形？

这是我的QtDsigner代码：

Answer 1

您不再需要创建PlotWidget对象，因为graphicsView是，您只需要更改：

model = doc2vec.Doc2Vec(documents1, size = 100, window = 300, min_count = 10, workers=4,dbow_words=1)

为：

pw = pg.PlotWidget()
self.graphicsView.pw.plot(pitch) #This is not working
