# Line-Plot

### Plotting without line

• In the previous section, we learn how to plot a line graph using pyplot alias plt.
• Now, we are going to see how to plot without the line or more specifically with different notations like 'o' for rings.
• Let's have a look at this code demonstration.
``````from matplotlib import pyplot as plt

time = [0, 1, 2, 3, 4]
revenue = [200, 400, 650, 800, 850]

plt.plot(time, revenue, 'o')
plt.show()``````

### Default X-Points

• While plotting, if we do not specify the x-axis then they will get the default values 0, 1, 2, 3, 4, 5, etc.
• Let's plot a line graph using only y-points:
``````from matplotlib import pyplot as plt

y-points = [3,5,9,2,1,6,7,8]
plt.plot(y-points)
plt.show()``````

### Multiple Line plots

• We can plot multiple line plots in the same graph.
• Matplotlib will automatically place the two lines on the same axes and give them different colors if you call `plt.plot()` twice.
``````from matplotlib import pyplot as plt

lst1 = [0, 1, 2, 3, 4]
lst2 = [200, 400, 650, 800, 850]
lst3 = [150, 500, 550, 550, 560]

plt.plot(lst1, lst2)
plt.plot(lst1, lst3)
plt.show()``````
