Python – Get Data From CSV and Create Chart

Hello everyone, this blog shows how we can import data from csv and plot as mesg grid chart in python libraries, through the help of Pycharm IDE (Community Version)

Prerequisite :

• 1. Install Python 3.6
• 2. Download Pycharm IDE (Community Version)
• 3. Basic knowledge of Python programming language

The following are the steps for creating mesh-grid in pycharm :
1. Installing NumPy,Pandas and Matplotlib libraries in Pycharm IDE :

• • 1. Create a scratch file in Pycharm.
  • 2. Click on “File” and goto settings.
  • 3. Goto “Project Interpreter” and click on ‘+’ symbol to add new libraries.

2. Writing python code for importing csv data and creating meshgrid :

• • 1. Create a csv file containing these data “-5,5,0.01”.
  • 2. Use this python code in your scratch file .

import csv
import numpy as np
import matplotlib.pyplot as plt

point = “”
with open(‘C:/Users/Helical/Desktop/Blog/Python/MeshGrid.csv’,’r’) as csvfile:
meshreader = csv.reader(csvfile, delimiter=’,’)
for row in meshreader:
point = point + ‘, ‘.join(row)
print(point)
meshpoints = point.split(‘,’)
points = np.arange(float(meshpoints[0]),float(meshpoints[1]),float(meshpoints[2]))
dx, dy = np.meshgrid(points,points)
z = (np.sin(dx)+np.sin(dy))
plt.imshow(z)
plt.colorbar()
plt.title(‘plot for sin(x)+sin(y)’)
plt.show()

• If you are able to sucessfully run the code, then you will generate mesh grid in an new Pycharm window.
