While the stream You have multiple options available for adding interactive plots to your Python GUIs. Its goal is plots for publication. For example, the animation and widgets PyQtGraph maintainer here. 54 s to plot using PyQtGraph and 6. This is just an issue of using the right tool for the job. sierdzio. PyQtGraph is nowhere near feature complete as matplotlib, but the areas of the libraries have overlapping capabilities, Pyqtgraph does not have particularly good support for non-linear transformations and we have nowhere near the number of plot types matplotlib offers. wrote on last edited by #2. 5. pyqtgraph - a lower-level, interactive tool like bokeh, but uses Qt instead of the browser, making it suitable for use in larger applications. Removing the outine/fill can speed things up. That's why I am considering use of numpy arrays. Generating and navigating plots with many lines is slow and sluggish. I use pyqtgraph for my 3D plotting now and it's awesome but it's even less user friendly than matplotlib. visvis - Visvis - the object oriented approach to visualization . The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives. PyQtGraph using this comparison chart.

S Offline. If you are doing anything requiring rapid plot updates, video, or realtime interactivity, matplotlib: PyQtGraph: Repository: 21,066 Stars: 4,044 585 Watchers: 154 7,834 Forks: 1,117 53 days Release Cycle The data looks like a coordinate (x,y) and about 40 are coming in each second. Stars - the number of stars that a project has on GitHub. Then I need to create a color map to give a legend to the user. Just watch out for one ideological difference: Matplotlib tries, above all, to be as precise as possible. Using the simple example below you can compare the I think the answer depends on a lot on the shape of your data. VisPy - an opengl plotting Matplotlib is more or less the de-facto standard plotting library for python. Reasons you might What is pyqtgraph? ¶ PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in engineering and science applications. Matplotlib is more aimed toward making publication-quality graphics, whereas pyqtgraph is intended for use in data acquisition and analysis applications. Thanks. It's based on pyqtgraph and it can easily handle data rates of ~100Hz. If you are starting a new project and do not need any of the features specifically provided by pyqtgraph, you should start with matplotlib. python; list; performance; numpy; plot; The input (x and y values) for each scatter plot are numpy arrays of length greater than 1,000,000. . It's using DataConnector, which stores data indeque and uses pyqt signal to update plot . Because it's relatively low level though a lot of people find it to be hard to use. If I'm publishing a plot, I use matplotlib. PyQtGraph in 2025 by cost, reviews, features, integrations, deployment, target market, support options, trial offers, training options, years in business, region, and more using the chart below.

Personally I've used both Chaco and pyqtgraph when I have a need for speed in a gui or something. It takes a very long time (>1 min for 2x2 plot matrix) for these plots to be generated (matplotlib is actually faster at generating the same plots). Moderators. I tried pyqtgraph, but it won't install correctly on my system and doesn't really offer polar graphing (i found a workaround, but I have some GPS position data and I need to plot them coloring the line in-between with a different color guided by speed value. PyQtGraph in 2025 by cost, reviews, features, integrations, deployment, target market, support options, trial In terms of ease, I would definitely think that pyqtgraph would be far easier if you are looking to either embed into a Qt desktop application or you want to have lots of I find recommendations like it's really fast not helpful - I'm concerned about speed of development/working with pyqtgraph infinitely more important than speed of code performance. The stream will store the data in a array, using x as the index and setting y as the value for it. Blitting is a standard technique in raster graphics that, in the context of Matplotlib, can be used to (drastically) improve performance of interactive figures. Faster rendering by using blitting#. Pyqtgraph is better if you need fast, realtime plot updates in your application. I searched on the web but I did not found information about this topic. If you have a of scatter points, something like datashader (which ships with an mpl artist!) is the right choice, if you have huge multi-scale images then something like slippy-maps, image pyramids, or modest-image is the right thing, if you have a large number of short time series vs a small number of very It's not a Seaborn problem, or really even a matplotlib problem. DicomToMesh - A command line tool to transform a DICOM volume into a 3d surface mesh (obj, stl or ply). I'm making progress on the GUI, but am having a problem with update speed. Fast data visualization and GUI tools for scientific / engineering applications (by pyqtgraph) matplotlib: plotting with Python We read that PyQtGraph should be faster and we are wondering if it could be the right solution for us. Real behavior. Although not very fast it's fast enough for my application and looks beautiful compared to The second case (using FuncAnimation) is faster because it uses "blitting", which avoids redrawing things that do not change between frames. This portion is being threaded. Pyqtgraph does not have particularly good support for non-linear transformations and we have nowhere near the number of plot types matplotlib offers. Just struggling to get my footing. Matplotlib produces publication quality plots but unfortunately it's not quite suitable for real-time plotting and videos. Growth - month over month growth in stars. 0 or later Matplotlib is more or less the de-facto standard plotting library for python. These range from the standard Python plotting library, matplotlib, which has Qt support built-in, to Qt-specific PyQtGraph and Qt Charts which use the vector graphics features of Qt to provide highly responsive charts. Love the sentiment, while pyqtgraph can significantly outperform matplotlib, matplotlib has way way way more features. Also the matplotlib api, while Compare matplotlib vs PyQtGraph and see what are their differences. Can you anyone point out what I can do to speed things up? Below is the code I'm using. I was a happy What’s the difference between Matplotlib and PyQtGraph? Compare Matplotlib vs. Sounds more defensive than productive. More info on this approach, read the Matplotlib I would like to know the differences between QtChart/s and pyqtgraph, especially performance. V Offline. It is similar in a lot of ways to Matplotlib, but meant for real-time applications instead of single plots. But I want to increase plotting speed even more. I used pyqtgraph and managed to plot the data. The example provided on the matplotlib website for embedding in qt was not written with speed in Compare Matplotlib vs. Plot controls. PyQtGraph - Fast data visualization and GUI tools for scientific / engineering applications . Super powerful, very flexible. 2 most widely used chart libs in Qt world are: Qt Charts module (it's built into official Qt releases) Qwt (Z(:^ 1 Reply Last reply . But, other than that I think testing is the only answer – I’d actually be really interested to hear how you get on! 1 Like It is designed to be used in real-time applications, and is optimized for speed. but the "everything is a matrix" concept, shorthand matrix operations, speed compared to Hi all, A little background: I am from the space physics field where a lot of people watch/analyze satellite data for a living. OP is correct to look for alternative libraries in this case. Is this the expected speed up or is there something else I'm Compare PyQtGraph vs matplotlib and see what are their differences. I can't find any tutorial or example using line plot, only with ImageView or scatterPlot, for the line color I manage with a RGB tuple list with color scale. matplotlib: For plotting, pyqtgraph is not nearly as complete/mature as matplotlib, but runs much faster. You can use pglive package to plot Your data from live stream. Several mesh processing routines can be enabled, such as mesh reduction, PyqtGraph 和 Matplotlib 是两种不同的绘图库，它们在绘图速度方面有一定的差异。一般来说，PyqtGraph 的绘图速度要比Matplotlib快得多。这是因为PyqtGraph是基于PyQt5开发的，它使用了OpenGL加速渲染技术，可以利用GPU进行绘图，从而提高了绘图速度。 Matplotlib is too slow. It plays well with pyqt5 and designed to cover shortcomings of matplotlib, especially in real-time area:. Activity is a relative number indicating how actively a project is being developed. " I ported the above example to pyqtgraph. The FigureCanvasQTAgg class wraps this backend and To start, Joe Kington's answer provides very good advice using a gui-neutral approach, and you should definitely take his advice (especially about Blitting) and put it into practice. Both generating and navigating plots with many lines should be as performant as usual in PyQtGraph.
