Overview

PyQtGraph

A pure-Python graphics library for PyQt5/PyQt6/PySide2/PySide6

http://www.pyqtgraph.org

PyQtGraph is intended for use in mathematics / scientific / engineering applications. Despite being written entirely in python, the library is fast due to its heavy leverage of numpy for number crunching, Qt's GraphicsView framework for 2D display, and OpenGL for 3D display.

Requirements

pyqtgraph has adopted NEP 29.

This project supports:

All minor versions of Python released 42 months prior to the project, and at minimum the two latest minor versions.
All minor versions of numpy released in the 24 months prior to the project, and at minimum the last three minor versions.
All minor versions of Qt 5 and Qt 6 currently supported by upstream Qt

Currently this means:

Python 3.7+
Qt 5.12-6.0
Required
- PyQt5, PyQt6, PySide2 or PySide6
- numpy 1.17+
Optional
- scipy for image processing
- pyopengl for 3D graphics
  - pyopengl on macOS Big Sur only works with python 3.9.1+
- hdf5 for large hdf5 binary format support
- colorcet for supplemental colormaps
- cupy for CUDA-enhanced image processing
  - On Windows, CUDA toolkit must be >= 11.1

Qt Bindings Test Matrix

The following table represents the python environments we test in our CI system. Our CI system uses Ubuntu 20.04, Windows Server 2019, and macOS 10.15 base images.

Comments

If arrayToQPath uses connect=all, use a different construction for QPainterPath

It's been discussed that the QDataStream >> QPainterPath operationis a real bottle-neck in arrayToQPath. Here is a stack overflow post that points out that QDataStream >> QPainterPath operation is really slow.

Taking a peak at what PythonQwt does, that project constructs an open QPolygonF and draw that. QPainterPath does have an addPolygon method, so we can generate a QPainterPath that is made up of a QPolygonF.

Doing some testing on examples/MultiPlotSpeedTest.py shows a significant performance boost when doing this. This PR shows 35 fps while master branch is at 25 fps.

This PR also incorporates a second optimization, it checks for NaN values on PlotCurveItem.updateData() instead of at arrayToQPath check, and allows for an optimization parameter to be passed to skip the NaN check which does cause a performance hit.

So first thing, the function is largely lifted from PythonQwt, so huge thanks to that project for figuring out this optimization.

~Some caveats, this does not work w/ Qt6; so definitely not ready for merging.~ Works with Qt6 now.

EDIT: on second thought, this NaN check might not be buying us anything... doesn't look like arrayToQPath is called any more often than PlotCurveItem.updateData... so we're just moving the calculation from one part of the library to another...

Added UML class diagram to give overview of the most important classes

As discussed in issue #848, a UML diagram that gives an overview of the most important classes can really help with understanding the PyQtGraph library.

I created a diagram in PlantUML, as suggested. I therefore made this PR so that people have can access to the source file. I think it would be a useful addition to the documentation but I don't know where (and how) to add it. For now I just added it to the doc folder as uml_overview.txt. Feel free move it of course.

The result is as follows. I'm curious to hear your feedback.

Optimize makeARGB for ubyte images

This PR optimizes the channel reordering portion of makeARGB by using the conversion routines of QImage.

It only optimizes for row major ubyte images and defers to the original code for the rest. Improvement in fps is measurable with VideoSpeedTest

Would such a PR that optimizes for specific data types be acceptable? Tagging @outofculture

Add support for Qt5

Are there any plans to add support for PyQt5?

I see you've got a nice wrapper around the Qt imports to support PySide/PyQt4. I had hoped that would mean a simple copy-pasta PyQt4 > PyQt5 but unfortunately you get hit with errors elsewhere (QApplication now being in QWidgets for example).

I can have a go at creating a PyQt5 fork in a branch and see how much I have to mangle it before it works, but I wanted to check nobody else was doing this first.

Avoid using ``np.linalg.inv()`` for transform inversion
This fixes not only latency but high CPU usage when inverting a Qt transform matrix.

There is a known recent issue in numpy pertaining to this: numpy/numpy/issues/17166

I've ripped off the "hard coded" solution from that issue verbatim and using it has reduced both latency and CPU usage in pretty much all mouse related interaction with ViewBox. I'm happy to write up profiling and test code for this in case there are any doubts.

There are even faster solutions inside the referenced issue that might be worth exploring as well; I know we have to keep py2 in mind but it might be worth some flag logic in this case since invertQTransform() seems to be used throughout ViewBox and GraphicsItem. This would explain why I'm seeing improvements outside my original use case (calling GraphicsObject.mapFromView() on label coordinates fed from the mouse).

I also would like to benchmark using *np.ravel() to pass the matrix results to QtGui.QTransform() since I've done that with good results in QPicture() drawings and it should in theory be faster then the existing multiple element access.

Implemented pColorMeshItem

As discussed in the issue #1262 I proposed here a minimal implementation of an item mimicking the pcolormesh function of matplotlib. As I didn't know what to do to make the pull request valid I decided to make it as minimal as possible. I am willing to integrate it more into pyqtgraph if someone gives me some directions. In particular a I think a kind of pColorMeshWidget with axis and Histogram would be an excellent end result of this work.

experimental line drawing mode for thick lines

Proof of concept using drawLines code from PlotSpeedTest.py. Drawing thick lines probably involves a polygon flood fill by Qt, which gets slower the more complicated the polygon gets. So the idea here is to draw many many short line segments. This has its own overhead but is far less than before.

To see it in action in PlotSpeedTest.py, ~~check enableExperimental,~~ set to line width more than 1 ~~and check skipFiniteCheck.~~

~~It's only meant to support fully finite data.~~

I don't use thick lines myself, so feel free to take over this PR.

Adding TextItem to plot changes the axis range (appears on Ver. 0.11, the bug was not present on 0.10)

Now that I am migrating to Version 0.11, I have noticed an annoying problem that was not present on 0.10.

When I add ArrowItem and TextItem to an existing plot, I get this:

Ticks_wrong

Whereas I would expect this (pyqtgraph ver. 0.10):

Ticks_right

I noticed that this happens only if I label the peaks by calling:

    def label_peaks(self, plot_wg2, pos_peaks, GLS = True, o_c = False, activity = False, MLP = False, DFT=False):

        if GLS == True and DFT == False and self.avoid_GLS_RV_alias.isChecked():
            x_peaks = pos_peaks[0][pos_peaks[0]>1.2]
            y_peaks = pos_peaks[1][pos_peaks[0]>1.2]
        else:
            x_peaks = pos_peaks[0]
            y_peaks = pos_peaks[1]


        if GLS == True:
            N_peaks = int(self.N_GLS_peak_to_point.value())
            if o_c == True:
                log = self.radioButton_RV_o_c_GLS_period.isChecked()
            elif activity == True:
                log = self.radioButton_act_GLS_period.isChecked()
            elif MLP == True:
                log = self.radioButton_RV_MLP_period.isChecked()
                N_peaks = int(self.N_MLP_peak_to_point.value())
            elif DFT == True:
                log = self.radioButton_RV_WF_period.isChecked()
                N_peaks = int(self.N_window_peak_to_point.value())

            else:
                log = self.radioButton_RV_GLS_period.isChecked()

            type_per = "GLS"
        else:
            N_peaks = int(self.N_TLS_peak_to_point.value())
            log = False
            type_per = "TLS"

        if len(x_peaks) <  N_peaks:
            N_peaks = len(x_peaks)
            print("You have reached the maximum number of %s peaks."%type_per)

        for i in range(N_peaks):

            text_arrow = pg.TextItem("", anchor=(0.5,1.9))

            if log == True:
                arrow = pg.ArrowItem(pos=(np.log10(x_peaks[i]), y_peaks[i]), angle=270)
                text_arrow.setText('%0.2f d' % (x_peaks[i]))
                text_arrow.setPos(np.log10(x_peaks[i]),y_peaks[i])
                
            elif log == False and GLS == True:   
                arrow = pg.ArrowItem(pos=(1/x_peaks[i], y_peaks[i]), angle=270)
                text_arrow.setText('%0.2f d' % (x_peaks[i]))
                text_arrow.setPos(1/x_peaks[i],y_peaks[i])
                
            elif log == False and GLS == False: 
                arrow = pg.ArrowItem(pos=(x_peaks[i], y_peaks[i]), angle=270)
                text_arrow.setText('%0.2f d' % (x_peaks[i]))
                text_arrow.setPos(x_peaks[i],y_peaks[i])


            plot_wg2.addItem(arrow)
            plot_wg2.addItem(text_arrow)

The "bug" appears only if I use TextItem. Adding ArrowItem behaves OK. So what changed w.r.t. version 0.10?

AxisItem-based grid item
The idea is to display the grid lines in a GridItem and not extend the AxisItems ticks.

This PR attempts to fix #1606, which reports that tick labels never seem to be displayed just right, when the grid is enabled.

Although the current PR seems to accomplish this, I am not quite happy with the current implementation:

I had troubles replicating the way how AxisItem calculates tick positions inside a GridItem. Therefore I just added the AxisItem objects to the GridItem and get the positions by calling the appropriate methods. Not nice but it works.

With this PR, the GridItem has been improved so that it gets the right tick positions from the corresponding AxisItems. However, it needs to be clarified if this approach shall be adopted altogether by AxisItem, without the need for users to manually create a GridItem.

Therefore, I marked it as draft. I am happy to receive/discuss ideas how the current approach can be improved.

Recently, #2385 was introduced that circumvents this problem, by hiding tick labels, when overlap even slightly the axis boundaries. Thus, the changes of this PR are only relevant if the style option 'hideOverlappingLabels' of all AxisItems are set to False.

I think it is useful, to have the possibility, to show tick labels at the plotted range start and/or end, when the tick label positions exactly match the start and/or end coordinate. Afaik matplotlib also does this.

Example to compare the behavior before and after

Extra ScatterPLot point on the GLViewWidget displays

I wrote a simple app using PyQt5 and Pyqtgraph to visualize data in 3D plot. Main window consists of GLViewWidget and 3 buttons to control the simulation. Here is an example of the code I used to do it. In fact I tries to plot an animated point, which moves according to the data given.

from PyQt5 import QtWidgets, QtGui, Qt, QtCore
import pyqtgraph as pg
import pyqtgraph.opengl as gl
import sim_viewer
import sys


class SimulationWin(QtWidgets.QMainWindow, sim_viewer.Ui_MainWindow):
    def __init__(self, data):
        super().__init__()
        self.setupUi(self)
        self.data = data
        self.state = 0
        self.id = 0

        self.x_data = list(self.data["vehicle_local_position"]["x"])
        self.y_data = list(self.data["vehicle_local_position"]["y"])
        self.z_data = list(self.data["vehicle_local_position"]["z"])

        self.viewer = gl.GLViewWidget()
        self.viewer.clear()
        self.viewer.setWindowTitle('STL Viewer')
        self.viewer.setCameraPosition(distance=50)

        g = gl.GLGridItem()
        g.setSize(200, 200, 200)
        g.setSpacing(10, 10)
        self.viewer.addItem(g)

        self.horizontalLayout_2.addWidget(self.viewer)

        self.pause_button.clicked.connect(self.start)
        self.next_button.clicked.connect(self.next)
        self.prev_button.clicked.connect(self.previous)

        self.point = gl.GLScatterPlotItem(pos=[self.x_data[self.id], self.y_data[self.id], self.z_data[self.id]],
                                          color=pg.glColor("#0072BD"))
        self.viewer.addItem(self.point)

        self.timer = Qt.QTimer()

    def update(self):
        self.point.setData(pos=[self.x_data[self.id], self.y_data[self.id], -self.z_data[self.id]])

    def start(self):
        self.state = 1 if self.state == 0 else 0
        if self.state:
            self.animation()
        else:
            self.timer.stop()

    def next(self):
        self.id += 1
        if self.id >= len(self.x_data) or self.id >= len(self.y_data) or self.id >= len(self.z_data):
            self.id = 0
            self.timer.stop()
            print("End Of Simulation")
        else:
            self.update()

    def previous(self):
        self.id -= 1
        if self.id < 0:
            self.id = len(self.x_data)
        else:
            self.update()

    def animation(self):
        self.timer.timeout.connect(self.next)
        self.timer.start(25)

    def closeEvent(self, a0: QtGui.QCloseEvent) -> None:
        self.state = 1
        self.start()
        self.viewer.clear()
        self.close()


if __name__ == '__main__':
    data = {
        "vehicle_local_position":{
            "x" : list(range(100)),
            "y" : list(range(100)),
            "z" : list(range(100)),
        }
    }
    app = QtWidgets.QApplication(sys.argv)
    window = SimulationWin(data)
    window.show()
    app.exec_()

The problem occurs from the start of application: sometimes extra point is added with coordinates (0, 0, 0) as shown in the screenshot: I tried to print self.viewer.items to find this point as an object, also tried to print self.point.pos but this didn't help - there were 2 items (Grid and ScatterPlot) and self.point.pos is equal to coordinates from data given from outside to simulate. This point may start blinking frame by frame: Or just stay in it position till the and of the program.

I tried to remove items, but extra point in this case is deleted with original point. It's necessary to notice, that this problem sometimes may not occur at all till the next launch

I uses: Python 3.8 Windows 10 PyQt5 5.15.7 PyOpenGL 3.1.6 Pyqtgraph 0.12.4

Almost don't understand, what to do with it. Here is additional screenshots:
