plot line between points pandas












0















I would like to plot lines between two points and my points are defined in different columns.



#coordinates of the points

#point1(A[0],B[0])

#point2(C[0],D[0])

#line between point1 and point 2



#next line would be

#point3(A[1],B[1])

#point4(C[1],D[1])    

#line between point3 and point 4



plot_result:

   A  B  C  D  E  F

0  0  4  7  1  5  1

1  2  5  8  3  3  1

2  3  4  9  5  6  1

3  4  5  4  7  9  4

4  6  5  2  1  2  7

5  1  4  3  0  4  7


i tried with this code:



import numpy as np

import matplotlib.pyplot as plt

for i in range(0, len(plot_result.A), 1):

    plt.plot(plot_result.A[i]:plot_result.B[i], plot_result.C[i]:plot_result.D[i], 'ro-')



plt.show()


but it is a invalid syntax. I have no idea how to implement this






python matplotlib

    In matplotlib a line between two points (x1,y1) and (x2,y2) is created via plt.plot([x1,x2], [y1,y2]).

The first two parameters of the method plot are x and y which can be single points or array-like objects. If you want to plot a line from the point (x1,y1) to the point (x2,y2) you have to do something like this:



for plot_result in plot_result.values: # if plot_results is a DataFrame

    x1 = row[0] # A[i]

    y1 = row[1] # B[i]

    x2 = row[2] # C[i]

    y2 = row[3] # D[i]

    plt.plot([x1,x2],[y1,y2]) # plot one line for every row in the DataFrame.

A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy...
