How to Multiplots on Same Canvas using Matplotlib

Subplot function can be used to plot multiple graphs in same canvas.

Case 1:- Create graph in same ROW

import matplotlib.pyplot as plt
import numpy as np
 
%matplotlib inline
    
x = np.linspace(0, 5, 11)
y = x ** 2
 
#Instantiate figure and axes object. 
#fig, ax = plt.subplots()
 
# bydefualt on not passing any parameters in constructor, Just a figure and one subplot
f, ax = plt.subplots(nrows=1, ncols=2)
ax[0].plot(x, y)
ax[0].set_title('Simple plot')

ax[1].plot(y, x)
ax[1].set_title('Simple plot')

Case 2:- Create graph in same Column

import matplotlib.pyplot as plt
import numpy as np
 
%matplotlib inline
    
x = np.linspace(0, 5, 11)
y = x ** 2
 
#Instantiate figure and axes object. 
#fig, ax = plt.subplots()
 
# bydefualt on not passing any parameters in constructor, Just a figure and one subplot
f, ax = plt.subplots(nrows=2, ncols=1)
ax[0].plot(x, y)
ax[0].set_title('Simple1 plot')

ax[1].plot(y, x)
ax[1].set_title('Simple2 plot')

Matplotlib/subplot/python Syntax and Analysis “fig, ax = plt.subplots()”

The Matplotlib subplot() function can be called to plot two or more plots in one figure. Matplotlib supports all kind of subplots including 2×1 vertical, 2×1 horizontal or a 2×2 grid.

# Import required library
import matplotlib.pyplot as plt
import numpy as np

#First create some toy data:
x = np.linspace(0, 5, 11)
y = x ** 2

#Instantiate figure and axes object. 
# bydefualt on not passing any parameters in constructor, Just a figure and one subplot
fig, ax = plt.subplots()
#Set Data
ax.plot(x, y)
#Set Title for the graph
ax.set_title('Simple plot')

Analysis of used code

#Instantiate figure and axes object. 
fig, ax = plt.subplots()

Important feature of the below code is we are using 2 variables for assignment on instantiation of object.

Reasoning

plt.subplots() is a function that returns a tuple containing a figure and axes object(s). Thus when using fig, ax = plt.subplots() you unpack this tuple into the variables fig and ax.Thus this can also be read as 2 below statement combined as one.

fig = plt.figure()
ax = fig.add_subplot(111)

f : matplotlib.figure.Figure object

ax : Axes object or array of Axes objects.

ax can be either a single  matplotlib.axes.Axes object or an array of Axes objects if more than one subplot was created. The dimensions of the resulting array can be controlled with the squeeze keyword, see above.

Wait for Magento 1.9.1

Historically Magento 1.x.0 version has always been vulnerable. And to plug-in the issues, magneto has always released 1.x.1 release in next 60 days. Historically 1.x.1 version has been one there most stable releases. Going by track record, I suggest users to avoid using magento 1.9 for production as upgrade or as a fresh installation. And its more interesting to observe that magento has release Magento CE 1.9.0.1 Version within 2 days of release of 1.9 version. 

After major release wait for bugs to be fixed. 

Review : washingmachineclinic.com Bangalore

This is  2 months pending work. This Review is about Washing Machine Clinic, Bangalore (washingmachineclinic.com). 

I had a pathetic experience from washingmachineclinic.com. Previous to actual experience I was told about their prompt and efficient service. So I decided to call them.

Got attended after number of follow up

I called them in one evening for the appointment. And I got appointment for next day. But unfortunately nobody turned up. But after a number of follow up it got attended next day.

Very High and Random charges

The person came  to my place and examined the washing machine. Immediately after examination, the person told me motor is damaged and needs to be changed. He quoted Rs 4,200.  I was confused, that the company is supposed to service all kind of washing machine and they deal with several part. How come the person knows exact price of the part? How come he told me price without consulting any paper or person. 

Going by logic that the price of machine is Rs 10,000. So how can only part be of Rs 4,200 I opted NOT to go for the service.

Next day I called Godrej service center. And I got my machine repaired in only Rs 2,400. Rs 1,800 less from what Washing Machine clinic quoted.

Always eager to change parts

In another experience of my friends, they called for the appointment.  They explained the problem. Surprisingly, at the same moment,  on same call,  they suggested one of part to get replaced. My friend was very surprised to hear that. The person is suggesting diagnosis without even examining. Later on he got it repaired WITHOUT any replacement of the said part from some other mechanic.

NOT RECOMMENDED 

After my and my friend experience I would highly recommend NOT to go for the service. Instead, I would recommend to opt for either Company customer service or any near by mechanic. 

Amethi : After 10 years, MP don't have House, Bank Account?

Hilarious, 2 time MP don't have a house in his constituency. After 10 years he don't have even a Bank account. Having house is a basic expectation from any MP. 

Moreover, for getting the residence proofs, occasional staying in the constituency is required.  And Surprisingly, his application was rejected with one the reason as, Rahul Gandhi don't even stay occasionally?

Amethi is my home : Rahul

I have many election speeches from Rahul Gandhi. One common sentence that I can hear in every speech since 2004 is "I am in-between my family. I in my home." The words has been consistent for last 10 years. But after this revelation, I am confused what does he really mean when saying those words. 

Is this emotional Drama?

I agree that we Indian's have been traditionally emotional. Historically we have taken more decisions based on emotions then on logic. It becomes very easy for any one to touch our emotional string. And historically people from Amethi too had a emotional connection with gandhi-nehru family. And Rahul Gandhi is using same for his elections. 

After 60 years, do you need more time to develop?

Amethi has been with Gandhi-Nehu Family for neary 60 years since Independence. In other words one family was having rule for 60 years. Even if one would have planned a long term(20 years)  plan for Amethi, he would have made it a Developed city. But sad part is Rahul Gandhi is still asking vote for issue on Poverty, Health and other basic amenities.  It is interesting to conclude  from the above instance that even after 60 years Amethi is fighting for basic amenities. Things could have been different if he would have stayed more.

And same conclusion applies for India as well.

Finally: SC issues notice to Centre on Lokpal appointment

PM is not silent, spoke 1117 times in 10 years

On 28th March, in a Hilarious facts presented by Media manager of Prime minister of  India, he spoke 1117 times in 10 years of in 3,650 days.According to him PM spoke every third day.  He also went on counted the occasions on which he has spoken.

According to him, PM spoke on dinners,in functions,  in Rajyasabha, in Loksabha, in front on  media, in election rallies and many many other times. Panjak Pachori also gave the reason why PM dont believed in speaking too much. He explained PM belief as "Empty vessel makes noise".

When the UPA II government faced heat during the coalscam, the Prime Minister was quoted as saying in the Rajya Sabha, "Hazaron jawabo se achchi hai khamoshi meri, na jaane kitne sawalo ki aabru rakhe. (My silence is better than a thousand answers, it keeps intact the honour of innumerable questions). "

So going by the statement, if PM speaks in a dinner, then next time he will speak will be only third day, even if he is required to make statement in Parliament. Because he speaks only once in three days. This is does not ends here, even he tweeted. Kam Bola Kaam Bola.

The PM's Media manager's statement was not that hilarious but tweet from PM was certainly more hilarious.

I hope India will get a speaking Prime-minister this time.
