Stretch Axis to Fit Graphics View QT Designer - python

I am trying to get the x axis to fill the entire of the graphics view.
What I have now (the x axis stops around two thirds of the way of the graphics view:
what I am trying to acheive:
I have tried plot.setXRange() with zero padding but that just changes the x axis limits.
I am also unsure about why I cannot see the origin (the x and y axis does not intercept)
Just in case, here is the generated python file from QT designer.ui:

I want to add a Viewbox to my code to make an AutoPan for X axis (pyqtgraph)

This is a GUI where I plot data from serial communication.
I want to add an AutoPan for my GUI but I don't know how.
I read there is an autopan in Viewbox but don't know how to implement it.
The option of Autopan is available when I launch the gui buy right clicking on the gui and selectign it manually but I want it to be enabled by default .

How to output to the application itself

I wrote a program that adds two numbers entered by the user into QLineEdit.
The result of the addition is output to the console in Pycharm.
How to make the result output to the application itself? (so that the user can see the answer).
I guess that there is some special method for this, but what is it?

It's not magic. You just have to create a widget that will display the answer. Then set the text on that widget when you do the calculation.
self.answerLabel = QtWidgets.QLabel(self.widget)
def cal(self, Probnei):
val_1 = self.First_n.text()
val_2 = self.Second_n.text()

How to update value of QLCDNumber on PyQT5?

I am trying to update my QLCDNumber, but I failed several times. In my code, you can see that I want to take the input numbers from the double spin boxes and show them as a total sum of the previous land use values in my LCD widget. I have created a function with .value() but it doesn't work properly. The code is bit large, but I highlighted the QLCDNumber part.
Screenshot here:

Created ui in Qt designer does not look the same when python code is run

I created a ui in Qt designer and transitioned the .ui file into .py file. However, when I run the python code, The ui does not look the same as in the designer when I run the code. I don't understand why this is happening as I can see all of the elements in the code?

I expect this:
but it looks like this:

For some reason you do not put all the widgets in the central widget?
I unfortunately could not see what result you want to get.
Try it:
