How to plot csv file data: PyQt5 tutorial - Part 06

Embed Matplotlib in PyQt5. The video is part 06 of PyQt5 GUI learning series. It contains instructions to make a csv file data plotting application. All columns of the data will be plotted and the header of each column will be labeled in the legend. The legend is draggable. Various themes are added to the Combo box widget. A user can select any theme for the plot. In this way, you will learn how to use PyQt5 designer to make GUI with combo box, properly selecting horizontal and vertical spacing, and the layouts. This application is very useful in generating rapid plots for various time series data as well.

Thank you for this. Trying out CSV files that I have right now.

very very useful video thanks a lot you are my savior!

So glad it was helpful!

Hi, thanks for the continued support! The lessons learned from this videos are very useful. This video shows how to integrate matplotlib into a PyQt5 environment.. Is is possible in addition to integrate matplotplib widgets? Specifically, the RangeSlider widget: from matplotlib.widgets import RangeSlider. I almost got it done using your code as a template, however, the mouse events aren't passed on to the RangeSlider . Any insights appreciated

[@pyshine_official]

Hi, Yes its possible, Multiple Matplotlib widgets can be added in the same way as in the above video. For slider input the widget can be added in a way similar to the video related to Video processing GUI at pyshine.com

Thanks for the video again, could you help me with getting multiple such canvasses which could then read data from different .csv files?

[@wonderman2864]

Hello, this is a great job! This video helped me a lot to do my project! Thank You so much. Can you please plot a csv file data using scatter as well in pyqt5?

[@pyshine_official]

You're welcome and thanks for pointing out, we can use plt.scatter function

[@fxois3318]

Seems to work in python 3.10, thank you so much ! Would it be possible by to add dynamically checkboxes that allows to hide/display individually each one of the curves of the csv file ?

[@pyshine_official]

Yes it is possible

[@AkshatJain-fh9zn]

Hey, you have done a great job! Can you provide a link to your source code? I'm also building a pyqt5 application and want to use interactive map for timeseries data. Your video inspired me a lot :)

[@pyshine_official]

Hello! So glad to hear it. You can find the source code in the description under video. pyshine.com/Make-GUI-With-Matplotlib-And-PyQt5/

Hi, thanks for this awesome video. How can a plot the x-axis as one of the columns of the CSV file? For example, if a have (time, velocity) table. Thanks

[@pyshine_official]

You're welcome! Please try the main_vsall.py code in this link pyshine.com/Drag-and-Drop-CSV-file-with-axis-selection-gui/. Any column can be selected as x axis and plot other as well

[@pablokrahl5481]

@@pyshine_official Thanks a lot and congratulations on the precious work! Best wishes

[@colsoft09]

Thanks for this great tutorial. You have done a good job. I have only one problem. When I open a CSV file, it plots alright in the window but it pops out another window titled Figure 1, but it has no plot in it. What can be the problem?

[@pyshine_official]

Hi! most welcome! Please use Matplotlib version 3.2.1 and Python 3.6.5 . Also which OS you are using? You can install the matplotlib as: pip3 install matplotlib==3.2.1

[@user-yh8qg1ug6x]

Not sure if you need it or not, it's a spyder IDE problem just add plt.ioff() in the code will solve it.

[@bitabehboodi5121]

I want to get a csv file from the user and connect it to the machine learning project. Can you help me about that?

[@pyshine_official]

Simply read csv via pandas library as a data frame df the df will be like a dictionary where keys will be colums and values will be vectors or lists. Use pd.read_csv() function

[@mohamedsamehmohamedzaki]

is there a video on how to plot real time data?

Nice video, I actually have a problem. After clicking a csv file, I'm not getting the csv file imported, what did I miss, I wrote whole code by watching it

[@pyshine_official]

Hi! Please copy the code from pyshine.com/Make-GUI-With-Matplotlib-And-PyQt5/

[@pyshine_official]

Also it is highly recommended to install matplotlib version 3.2.1

[@1UniverseGames]

@@pyshine_official thanks for the response. Yes I'm using the 3+ version
