• There are several parameters that determine
• what the figure looks like

4
Example

• fig  plt.figure() axes1  fig.add_axes(0.1, 
  0.1, 0.9,0.9)  axes1.plot(arr1, arr2, 'b--')
• axes1.plot(arr2, arr1, 'r.-')
• O/P

5

• Alpha parameter can be mentioned that
• defines the transparency in the plot.
• Eg fig  plt.figure() axes1  fig.add_axes(
  0.1, 0.1, 0.9,0.9)   axes1.plot(arr1, arr2, co
  lor  '808000', 
• lw  10) axes1.plot(arr2, arr1, color  '0
  0FF00', 
• lw  0.25) axes1.plot(arr1, arr12, color 
   '00FF00', 
• lw  1)

6
Setting line,changing line colors and adding
markers

• The following color abbreviations are supported
• Character color b blue g
  green r red
  c cyan m magenta
  y yellow k
  black w white
• For other color shades hexadecimal color coding
  can be used.

7

• O/P

8

• Ls parameter defines the line style as mentioned
  in the previous table .
• Lw defines the line width that we wish to have in
  the plot
• Egfig  plt.figure()
• axes1  fig.add_axes(0.1, 0.1, 0.9,0.9) 
   
  l,b,w,h -0 and 1
• axes1.plot(arr1, arr2, color  '808000', lw 
   10, ls  '--')axes1.plot(arr2, arr1, color  '0
  0FF00', lw  3.25, ls  '')axes1.plot(arr1, arr1
