Colours
We can either use character codes or the color names as values to the parameter color in the plot().
Character Colour
'b' blue
'g' green
'r' red
'c' cyan
'm' magenta
'y' yellow
'k' black
'w' white
Linewidth and Line Style
The linewidth is given in pixels. The default is 1 pixel. You can increase the number to increase the width.
Linestyle can be "solid", "dotted", "dashed" or "dashdot".
Let us now make some graphs :
Plotting a Line Chart
• Single line chart
import matplotlib.pyplot as plt
city=['Delhi','Mumbai','Chennai','Kolkata']
temp=[35,21,40,22]
plt.xlabel('Metro Cities')
plt.ylabel('Temp in Celsius')
plt.title('Temperature Study of the Day')
plt.plot(city,temp,marker='*',markersize=10,color='red',
linewidth=2, linestyle='dashdot')
plt.show()
The above code will create a line graph as shown below:
Temperature Study of the Day
40.0
37.5
35.0
Temp in Celsius 30.0
32.5
27.5
25.0
22.5
Delhi Mumbai Chennai Kolkata
Metro Cities
