Type '''x = linspace inside the brackets (0, 50, 10)'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now let us draw a simple '''sine curve''' using these '''points.'''

Type '''plot inside the brackets (x, sin(x))'''

|-

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| This happened because we selected few '''points''' that is 10 for a large '''interval''' of 0 to 50.

'''Plot''' '''function''' does not '''plot''' the '''analytical function.'''

It plots the '''points''' given by '''analytical function'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''y = linspace(0, 50, 500)'''

'''plot(y, sin(y))'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now, let us use '''linspace''' command to get 500 points between 0 and 50 and draw the '''sine curve''' again.

Type

'''y = linspace inside the brackets (0, 50, 500)'''

'''plotinside the brackets (y, sin(y))'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot Window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we see a '''sine curve''' with a '''smooth curve'''.

Notice we also have two '''plots''' one '''overlaid''' upon another.

In '''pylab''', by default all the '''plots''' are '''overlaid'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| To '''distinguish''' between two '''overlaid plots''' we use '''legend''' '''command.'''

Type '''legend inside the brackets( square brackets['sin(x)', 'sin(y)'])'''

The '''legend''' '''command''' takes '''parameter '''as a '''list''' of '''strings.'''

Then it assigns '''strings''' to''' plots''' in the order they were created.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot Window]

Exercise 1

Draw two plots for the given form

# First plot is a parabola of the form '''y = 4(x ^ 2)'''
# Second plot is a '''straight line''' of the form '''y = 2x + 3''' in the '''interval''' -5 to 5.
# Use legends to indicate each plot.

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Pause the video. Try this exercise and then resume the video.

Draw two '''plots''' first plot being a '''parabola''' of the form '''y = 4(x ^ 2)''' and the second being a '''straight line''' of the form '''y = 2x + 3''' in the '''interval''' -5 to 5.

Use '''legends''' to indicate what each '''plot''' is doing.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''x = linspace(-5, 5, 100)'''

'''plot(x, 4 * (x * x))'''

'''plot(x, (2 * x) + 3)'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| <Switch to the terminal for solution.>

Type '''x = linspace inside the brackets (-5, 5, 100)'''

We can obtain the two '''plots''' in different '''colours''' using the following '''commands'''.

Type

'''plot inside the brackets (x, 4 * (x * x)) '''

'''plot inside the brackets (x, (2 * x) + 3)'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''legend([r'$y = 4(x ^ 2)$', r'$y = 2x + 3$']) '''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now, we will add a legend to identify the plots

Type '''legend inside the brackets( inside square brackets [r'$y = 4(x ^ 2)$', r'$y = 2x + 3$']) '''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot Window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We can see the '''legend''' added to the plot.

<Pause>

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''clf()'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Next we will learn to '''switch''' between the '''plots''' and perform '''operations''' such as '''saving''' the '''plots''' etc.

Let us see how to accomplish this.

But before we move on, let us '''clear''' our '''screen'''.

Type '''clf()'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''x = linspace(0, 50, 500) '''

'''figure(1)'''

'''plot(x, sin(x), 'b')'''

'''figure(2)'''

'''plot(x, cos(x), 'g')'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Switch to '''terminal'''

Type '''x = linspace inside the brackets (0, 50, 500) '''

To accomplish more control over '''individual plots''' we use the '''figure command '''

Type '''figure(1)'''

'''plot inside the brackets (x, sin(x), 'b')'''

'''figure(2)'''

'''plot inside the brackets (x, cos(x), 'g')'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot Window]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we have two''' plots''', a '''sine curve '''and a '''cosine curve''' in two different '''figures'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Ipython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| The '''figure command''' takes an '''integer''' as an '''argument. '''

This is''' '''the '''serial number''' of the '''plot''' to select corresponding '''plot'''.

All the''' plot commands '''we run hereafter are applied to the selected '''plot'''.

In this '''example, figure''' 1 is the '''sine plot''' and '''figure''' 2 is the '''cosine''' '''plot'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''title('cos(x)')'''

'''savefig('cosine.png')'''

'''figure(1)'''

'''title('sin(x)')'''

'''savefig('sine.png')'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| For example, we can '''save''' each''' plot '''separately.

Type

'''title('cos(x)')'''

'''savefig('cosine.png')'''

'''figure(1)'''

'''title('sin(x)')'''

'''savefig('sine.png')'''

The figures will be saved in current working directory. Now close both the plot windows.

|-

Draw a '''line''' of the form '''y = x''' as one '''figure''' and another '''line''' of the form '''y = 2x + 3'''.

Save each of them.

|-

'''figure(1)'''

'''x = linspace(-5, 5, 100)'''

'''plot(x, x)'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Switch to the '''terminal''' for solution.

To solve this problem we will use the '''figure command''' to create first '''plotting area'''

Type

'''figure(1) '''

'''x = linspace(-5, 5, 100) '''

'''plot(x, x)'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''plot(x, ((2 * x) + 3))'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now use the '''figure command''' to create second '''plotting area''' and '''plot '''the''' figure'''

Type

'''figure(2) '''

'''plot(x, ((2 * x) + 3))'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now to switch between the '''figures''' we can use '''figure command'''.

We will save the figure as follows

Type

'''figure(1)'''

'''savefig('plot1.png')'''

'''figure(2)'''

'''savefig('plot2.png')'''
