Matplotlib Definition and 17 Threads

I'm running Python 3.8.3 on Windows 10 and was have installed matplotlib, but I can't get it to work. If I try import matplotlib then first it seems to spit out some output (always the same) from a couple of basic test programs I wrote (which is really weird), then just gets a bunch of errors...

import matplotlib.pyplot as plt R = 2 for x in range(0,50): y = x**R # plt.plot(x,y,marker = 'o') plt.plot(x,y,'--') plt.xlabel('X-axis') plt.ylabel('Y-axis') plt.title('plot test') plt.legend() plt.show()

I use matplotlib to create files.pgf that I can \include{} in my latex documents. All works nicely, except when I want to make a reference to some equation of my latex document. For example, I when plot several curves on a graph and label them as "Coming from expression ..." where ... is...

I want to submit an article to an aps journal, so the labels of the figures have the "Times New Roman" font. I had used the package matplotlib to get the figures and I want to make "Times New Roman" the default font. So, what code I need to write for this to be achieved? Note that I used the...

I had Python 3.7.3 installed on my laptop. I decided to upgrade to 3.8.0, and after installing all necessary packages, uninstall the old version. The installation of 3.8.0 was successfully done. With pip, I installed scipy, numpy and sympy. Now when I tried to install matplotlib, it threw an...

I wrote a basic plotting code and I run it on the VS code my somehow the program cannot run it I deleted python itself and VS code and I downloaded them again, but the problem is not solved. import matplotlib.pyplot as plt x = [1,2,3] y = [4,5,6] plt.plot(x,y) plt.show()...

How could I improve the below code to fit all the xtickslabels on my plot more nicely (i.e. more spacing between the labels, higher resolution)? Thanks! from pyplot import * yearmonthday=['2003-01-01', '2003-02-01', '2003-03-01', ...] #len(yearmonthday) is 155 kwh = [88883, 99221, 100002, ...]...

I am trying to animate a plot of two distinct points (blue and green points) moving about the complex unit circle using Python's Matplotlib library. The problem I am having is that the animation does not remove and update the previous data points but rather sequentially smears it on the unit...

Hi I have a 2d trajectory of a center of mass which I have saved in an array such that r=[[x(t_1),y(t_1)],[x(t_2),y(t_2)],...,[x(t_n),y(t_n)]] where x is x coordinate of the position and y is the y-coordinate of the position. I have tried this: xx = [t[0] for t in r] xy = [t[1] for t in r]...

Hi, I want to plot the vector field ##\vec F = ye^x \hat i + (x^2 + e^x) \hat j + z^2e^z \hat k## The code I have tried: # The components of the vector field F_x = y*e**x F_y = x**2 + e**x F_z = z**2*e**z# The grid xf = np.linspace(-0.15, 2.25, 8) yf = np.linspace(-0.15, 2.25, 8) zf =...

The Earth's magnetic field is cylindrically symmetric and can be described using cylindrical coordinates, (ρ,z,φ). The components of the magnetic field are given by: (B_φ) = 0 (B_ρ) = −∂A/∂z, (B_z) =(1/ρ) * ∂(ρA)/∂ρ. The vector potential for a dipole field is given by (A_φ) = (B_e)(ρ) *...

Homework Statement I'm plotting moving particles and I need a way to refresh the graph space with every loop. Meaning I want the points to NOT leave a trail of other points behind them . Basically I want to get rid of the old points as I plot new ones. Homework Equations N\A The Attempt at a...

Hello guys, I programmed a physics simulation where a particle with some initial conditions bounces off the walls of a 2d container. The simulation also includes gravity in the y-coordinates. The aim of the project is to produce a visual animation and further on include more particles and...

I've looked around for this and so far haven't found anything close enough to what I'm after. In matplotlib, I want to get a specific tick on the x-axis to label a particular value. I know how to use axvline to get a vertical line marking that point, which is good, and I know how to add...

Any python/matplotlib experts out there?? This one has been driving me crazy all day. I have three vectors, azimuth, frequency and power, which I would like to histogram and plot on a polar axis. I can plot a scatter plot this way no problem but the histogram gets messed up somehow. An example...

Hi, I'm currently working on a C program where I have a huge 2d array that changes with time, so in the end, what I have is a 3d array (double 25*24000*100) in a plain text file (about 700MB). I tried to import with Mathematica7 as a "Table" but after a long time (about 15 minutes) the kernel...

Hi there, I am plotting some data onto a hammer plot using ipy- matplotlib. The axes on the plot range from alpha= -pi:pi and beta=-pi/2:pi/2. I have a value (lets call it delta) for each point on the plot where (alpha=integer,beta=integer). I have arranged the delta values in ascending order...
