Integrate ploting of simple graphs using matplotlib about calculator_pyqt HOT 19 CLOSED

Ok then integrate PyQtgraph.

from calculator_pyqt.

yes it is allowed

from calculator_pyqt.

please provide some description on this.. like which graphs and how to modify etc..

from calculator_pyqt.

I'm working on it. Will revert soon

#27 PR opened for graphing options. @taapas1128 Please review

from calculator_pyqt.

This is assigned to @07kshitij . Try to follow the proper procedure before directly working on it .

from calculator_pyqt.

Okay, I'll reconsider the same

After a lot of reading, what I found was math.some_function works only for scalar values, i.e. to get values corresponding to a single input, while np.some_function works for arrays. Since, for plotting purposes we need at least a few data points, taking them as an array (in the form of a range of function to be plotted) is the most ideal way IMO. So, I don't see any way to avoid using numpy. Also, the StackOverflow link mentioned by you works only for non-math functions (as they operate on arrays fine), while functions like sin/cos give typeError. Replacing them by np.sin etc works perfectly fine.

Yeah numpy is fine then I just wanted to know why you needed that dependency . And did you deal with the other issue ?

from calculator_pyqt.

Actually I didn't understand what you meant by using Tkinter dependency(Don't know much about it, I read a bit but didn't get much). Can you please elaborate more. (As to what part of code feels erroneous to you)

from calculator_pyqt.

Actually the window that opens while plotting the graph possibly it does not open a PyQt window but a Tkinter window by default. So read the Stack overflow article there instead of calling the mathplotlib library the import mathplotlib with PyQt dependency .

Okay, will read about it.

I came across this StackOverflow article that uses pyqtgraph, a GUI library built on PyQt and numpy. It basically does the same function as matplotlib, but doesn't use it. (Basically it's a PyQt lib). Will it be fine if I use it?

Yes you can integrate it .. didn't the previous article about matplotlib with pyqt suffice ?

It was too big to integrate into the already set code. In PyQtgraph, I simply need to import pyqtgraph and replace matplotlib everywhere with PyQtgraph.

I'm opening a PR for the same, kindly review.

Isn't there a relatively simpler way out (like taking input from the keyboard). For implementing a new pop-up with function reference to the original Calculator_class, I think we need one more *.py and one *.ui file for the new dialog. But redirecting the buttons to the new dialog still remains tricky.
(P.S. I read the StackOverflow article. We can't do it that way as it takes input from the keyboard, i.e. no use of all those buttons etc, and integrating them is the real challenge)

Okay I understand you can do one thing take the input equation as usual but delete the range button; instead when the plot button is clicked ask for range using a popup.

Okay great, one more thing, is taking inputs from keyboard allowed, for the range form, I think of displaying 3 text boxes of starting index, ending index and step size and ask the user to enter the corresponding values from keyboard. Is it allowed?
