pyqtgraph...

[David Francis]

Hi, I am new to programming but have managed to design a GUI interface for my project. I would now like to have a graph on my GUI but when I add one it takes over the whole window... is there a way of imbedding a graph into a text box??

1. A text box is a text box. I wouldn't recommend embedding whatever into it.

2. "takes over the whole window" ?? Did you read the docs concerning PlotWidget etc.?

3. Did you launch pyqtgraph.examples.run(), and thoroughly look the sources? You will see there some embedding examples

4. Google is not your foe!

Sorry for being nasty, but if you are a beginner, and instead of doing some work you immediately cry "help!", you will remain a beginner forever.

Hi David, 

While the guy above me was being mean to you for some unclear reason, he is not all wrong. 

I suggest you should google “Plotting PyQt5” or “PyQt5 and pyqtgraph”. I remember there are a few very nice tutorials out there. The thing you are looking for is to embedded a custom widget to your GUI. That custom widget can be a PlotWidget (which is from pyqtgraph package).

Hi,

Thanks for the information, I obviously have tried google and been trolling the internet for the last 3 weeks trying to sort this but to no avail....

But thanks for responding to my question

Hi David,

I have done a lot of work embedding images, plots and charts into PyQt5 applications. Please describe a bit more what you are trying to accomplish and I'll see if I can get you pointed in the right direction. I'm pretty maxed out with work, so it may be a few days before I get back to you.

Regards,
Erik

hi 

If you want i had written a short example using pyQt and pyqtgraph if it could help :

from PyQt5.QtWidgets import QApplication,QVBoxLayout,QHBoxLayout,QWidget,QPushButton,QGridLayout

from PyQt5.QtWidgets import QInputDialog,QSlider,QCheckBox,QLabel,QSizePolicy,QMenu,QMessageBox,QSpinBox

from PyQt5.QtWidgets import QShortcut

        # done  when you start the class 

        super(WIND, self).__init__() # permet d'initialiser la class WIND avec init de la la class Qwidget dont elle depend

        self.setup()

        self.ActionButton()

    

    def setup(self):

        

        self.vbox1=QVBoxLayout() #layout Vertical box

        self.checkBox1=QCheckBox('Check box',self)

        self.box3.editingFinished.connect(self.Actionbox)

        self.Button1.clicked.connect(self.ActionButton1)

        self.checkBox1.stateChanged.connect(self.ActionCheckBox1)

        

    def Actionbox(self):

        print('box', self.box3.value())

    

    def ActionButton1(self):

    appli = QApplication(sys.argv) 

    #appli.setStyleSheet(qdarkstyle.load_stylesheet_pyqt5()) Si tu veux en noir 

    e = WIND()

    e.show()

    appli.exec_()

Hi Erik,

Thanks you for your offer, I am going to have a go myself and see if I can sort it, if not I may give you a shout...

Thanks again

Dave

[David Francis]

Hi Julien,

Thanks for your input I will give it a try.

Many thanks Dave

Here's a utility function I use to add a plot item to a QWidget, then you can just call widget.plotItem.plot(...)...

def add_plot(widget):
    """Add a plot item (that will behave nicely) to a basic QWidget (e.g.
    generated by QTDesigner).

    widget: QWidget

    returns None
    """

    layout = QtGui.QHBoxLayout()
    widget.setLayout(layout)
    layout.setSpacing(0)

    widget.plotView = pg.GraphicsView()
    layout.addWidget(widget.plotView)

    widget.plotItem = pg.PlotItem()
    widget.plotItem.resize = widget.resize
    widget.plotView.setCentralItem(widget.plotItem)
