Pyqtgraph setconfigoption. 用了PlotWidget,直接嵌入到PyQt .
Pyqtgraph setconfigoption I created a few plots without trouble, but when I went to change import pyqtgraph as pg 可以使用pyqtgraph. setConfigOption('background', '#f0f0f0') before the widget is created, however, this does not apply to the legend items. If there are no movable objects under the mouse cursor, then dragging with the left button will pan the scene instead. setConfigOptions (** opts) [source] ¶ Set global configuration options.

QApplication. 用了PlotWidget,直接嵌入到PyQt import sys import numpy as np import pyqtgraph as pg # Set white background and black foreground pg. So essentially, you could include this snippet of code in any file that you know will be imported after the QApplication is created. 3k次,点赞4次,收藏13次。本文介绍了如何使用PyQt5和pyqtgraph库创建一个具有自定义旋转横坐标轴的直方图控件。通过定义`RotateAxisItem`类实现旋转坐标轴,然后在`PyQtGraphHistWidget`类中构建直方图,包括设置数据、绘制直方图条形以及添加鼠标移动时的实时信息显示功能。 pyqtgraph. setConfigOption调整左键操作。涉及的技术包括pyqtgraph库的配置和鼠标交互设置。 pyqtgraph. 文章浏览阅读1. instance() if inst is None: QAPP = QtGui. plot():将一组新的数据添加到现有的绘图小部件; GraphicsLayout. 1 什么是pyqtgraph? PyQtGraph是Python的图形和用户界面库,它充分利用PyQt和PtSide的高质量的图形表现水平和NumPy的快速科学计算与处理能力,在数学、科学和工程领域都有广泛的应用。 其主要目标是: 为数据(绘图,视频等)提供快速可交互式图形显示 We would like to show you a description here but the site won’t allow us. 我在创建小部件之前使用命令 pyqtgraph. getConfigOption (opt) [source] # Return the value of a single global configuration option. clear() followed by self. setConfigOption('antialias',True) # 等价于上一句,所不同之处在于setconfigOptions可以传递多个参数进行多个设置, 六、Qt 快速教学 几乎所有的PyQtGraph库的图形界面都是由Qt来生成。Qt的文档写得很好,我们鼓励所有pyqtgraph开发人员熟悉它。本节的目的是介绍如何使用Qt(使用PyQt或PySide)编写pyqtgraph开发者程序。窗口和布局 Qt GUI几乎都是由几个基本组件组成: 一个窗口。这通常由QMainWindow提供,但请注意,如果 在pyqtgraph中也使用相同的系统,但pyqtgraph也允许许多指定相同样式选项的简写方法。 pyqtgraph中的许多函数和方法都接受指定线条样式(笔),填充样式(笔刷)或颜色的参数。 对于大多数这些函数参数,可以使用以下值: matplotlib 很方便,但是 pyqtgraph 是专门为 性能优化 过的,会更快。; 提高绘图效率的方法1: 利用 PlotDataItem 的 connect="finite" 来批量绘制 多段线 。; 有些人会推荐使用下面的方法提高效率,但是如果按照下面的方法进行配置的话,connect=" finite" 就失效了。原因未知。 The following are 13 code examples of pyqtgraph. 14.
