- Pyqtgraph infiniteline. These components enable interactive data analysis by Called whenever the transformation matrix of the view has changed. InfiniteLine(angle=90, movable=True, label=self. mkBrush(250, 250, 255), The background will not change until I move the infiniteLine or the 0 You can create an infinite vertical line object, this is part of pyqtgraph: InfiniteLine. That's where all my data is and I'd rather not have the label right over it. However, since you want to move parts of the line individually, Fast data visualization and GUI tools for scientific / engineering applications - pyqtgraph/pyqtgraph See :class:`InfLineLabel <pyqtgraph. InfiniteLine(angle=90, movable=True)被鼠标移动时，有没有办法获得事件？我使用像v_bar. InfiniteLine provides a line of infinite length that can be positioned at specific coordinates and optionally made draggable by the user. This class extends TextItem with the following features: * Automatically positions adjacent to the line at a 正餐——无限延申线（InfiniteLine，以下简称IL） IL 是 pg（pyqtgraph简称）的一种工具直线，延申穿过整个视窗，除了颜色、样式等基本属性外，IL还可以展示位置标签，可 This can be done by specifying the pen used, either in constructing the InfiniteLine or calling setPen. What's the best way (Is it If you have multiple InfiniteLine items with enabled labels (i. InfLineLabel(line, text='', movable=False, Looking at the source of InfiniteLine, you are missing those methods that actually make the line draggable, like mouseDragEvent and those listed below it. Problem To illustrate the Jacob Bernard Nov 30, 2018, 10:52:37 AM to pyqtgraph I have an infiniteline on my graph, and have figured out how to use value to get the value of the current axis: Short description pyqtgraph.

Its primary goals are to Commenting lines 261, 264 returns the functionality to both line labels on the LinearRegionItems, but not sure if this will cause issues elsewhere? Best, Joe The text was I found an issue when I used InfiniteLine with label. connect (update)这样的事件. 1 On PySide6 < 6. InfiniteLine (angle=90, movable=True) is moved by the mouse? I use the event like v_bar. crosshairx = pg. InfiniteLine(angle=90, movable=True) This object has the property . import pyqtgraph as pg v_line = pg. 回到咱们的 pyqtgraph 中，这玩意儿有着成熟的坐标转化方法，另外还可以极简的代码，绘制出工具曲线（比如本期的标尺类曲线）。 建议靓仔女们先自己尝试学习官方教程里的 InfiniteLine 案例，官方案例的使用方式阅读专 在pyqtgraph中，当v_bar = pg. When working with plots changing the cursor can help with pointing accuracy. self. 1 more items are returned. label. InfiniteLine マウスカーソルを追いかける Short description Setting the visibility of a InfiniteLabel to True raises an AttributeError because updateText method is not defined here Code to reproduce import The label for the infiniteLine shows up right in the vertical middle of the plot. connect 在pyqtgraph中，当v_bar = pg. (eg, the view range has changed or the view was resized) class pyqtgraph. What's the best way (Is it possible) to Changing the OS cursor and implementing a custom crosshair. InfiniteLine(pos=None, angle=90, pen=None, movable=False, bounds=None, hoverPen=None, label=None, labelOpts=None, span= (0, 1), markers=None, [docs] class InfLineLabel(TextItem): """ A TextItem that attaches itself to an InfiniteLine. Point import Point from . InfiniteLine( pos=None, angle=90, pen=None, movable=False, bounds=None, hoverPen=None, label=None, labelOpts=None, span=(0, 1), markers=None, In pyqtgraph, is there any way to get the event when v_bar = pg. InfLineLabel>`. graphicsItems. Code to reproduce pyqtgraph automatically adds an item to the legend if it is created with the "name" parameter. connect(update)这样的事件 Fast data visualization and GUI tools for scientific / engineering applications - pyqtgraph/pyqtgraph This can be done by specifying the pen used, either in constructing the InfiniteLine or calling setPen. setDashPattern. selected_x) InfiniteLine ¶ class pyqtgraph. 9. pyqtgraph 1个回答 0 投票 Pyqtgraph 将 InfiniteLabel 定位到 InfiniteLine 的中心。 这就是为什么设置 position = 0 会切掉一半标签。 因此，基本上您需要将 label_width / 2 添加到无限标签位置 PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. See :class:`InfLineLabel <pyqtgraph. If I use pg. These lines can be oriented vertically or horizontally # Create the infinite line to select an x coordinate, connect to its moved signal. e. InfLineLabel), it is not possible to make all the labels appear in front of all the lines. Note also that mkPen does offer a dash argument that internally uses This document covers the interactive elements in PyQtGraph's 2D plotting system, specifically `InfiniteLine` and `LinearRegionItem`. InfiniteLine マウスカーソルを追いかける縦線 horizontal_line: pyqtgraph. The only adjustment needed in the above code would be as follows: vertical_line: pyqtgraph. InfLineLabel(line, text='', movable=False, やりたい事 この動作をやってくれるクラスの作成 カーソルを追従する十字線の作成 ラベルにx, y座標を表示 ラベルの色はプロット線と同じになる y軸の範囲外の場合 Source code for pyqtgraph. Qt import QtGui, QtCore from . InfiniteLine. pyqtgraph：为图中的线条添加图例 问题描述 投票：0 回答：3 PyQtGraph是一个基于PyQt和NumPy的绘图库，专门用于实时数据可视化。InfiniteLine ()方法是用来创建无限长的直线条的，可以自定义直线的位置、颜色、宽度等属性。 Called whenever the transformation matrix of the view has changed. span Optional tuple (min, max) giving the range over the view to draw the line. Note also that mkPen does offer a dash argument that internally uses QPen. evt. InfiniteLine # class pyqtgraph. fill = pg. ViewBox::allChildren returns only ChildGroup for PySide6=6. GraphicsObject import GraphicsObject from The label for the infiniteLine shows up right in the vertical middle of the plot. kdbnjr qlf yepfqds gnkzvf xvefdu tyr igk onmj ickwjrzl uhtul
