Sometimes it is necessary or desirable to place the legend outside the plot. The following code shows how to do it.
import matplotlib.pylab as plt
fig, ax = plt.subplots(1, 1, figsize=(10,6)) # make the figure with the size 10 x 6 inches
fig.suptitle('Example of a Legend Being Placed Outside of...
An Explain infront of a select query shows you how the query will be executed. This way you to see if the query uses an index or if you could optimize your query by adding an index.
Example query:
explain select * from user join data on user.test = data.fk_user;
Example result:
id select_type...
1. Character Class
Character class is denoted by []. Content inside a character class is treated as single character separately. e.g. suppose we use
[12345]
In the example above, it means match 1 or 2 or 3 or 4 or 5 . In simple words, it can be understood as or condition for single characters (...
A less known builtin feature is Controller Action injection using the FromServicesAttribute.

The ng-mouseenter and ng-mouseleave directives are useful to run events and apply CSS styling when you hover into or out of your DOM elements.
The ng-mouseenter directive runs an expression one a mouse enter event (when the user enters his mouse pointer over the DOM element this directive resides i...
This directive is useful to limit input events based on certain existing conditions.
The ng-disabled directive accepts and expression that should evaluate to either a truthy or a falsy values.
ng-disabled is used to conditionally apply the disabled attribute on an input element.

You can use the zip operator to make request in parallel and combine the results eg:
Observable.zip(api.getRepo(repoId1), api.getRepo(repoId2), (repo1, repo2) ->
{
//here you can combine the results
}).subscribe(/*do something with the result*/);
C++11 introduced core language and standard library support for moving an object. The idea is that when an object o is a temporary and one wants a logical copy, then its safe to just pilfer o's resources, such as a dynamically allocated buffer, leaving o logically empty but still destructible and co...
To perform elementwise multiplication on tensors, you can use either of the following:
a*b
tf.multiply(a, b)
Here is a full example of elementwise multiplication using both methods.
import tensorflow as tf
import numpy as np
# Build a graph
graph = tf.Graph()
with graph.as_default():

Variable tensors are used when the values require updating within a session. It is the type of tensor that would be used for the weights matrix when creating neural networks, since these values will be updated as the model is being trained.
Declaring a variable tensor can be done using the tf.Varia...

Suppose we want to count how many counties are there in Texas:
var counties = dbContext.States.Single(s => s.Code == "tx").Counties.Count();
The query is correct, but inefficient. States.Single(…) loads a state from the database. Next, Counties loads all 254 counties with all of the...
select_dtypes method can be used to select columns based on dtype.
In [1]: df = pd.DataFrame({'A': [1, 2, 3], 'B': [1.0, 2.0, 3.0], 'C': ['a', 'b', 'c'],
'D': [True, False, True]})

This example demonstrates how to place 3 buttons in total with 2 buttons being in the first row. Then a wrap occurs, so the last button is in a new row.
The constraints are simple strings, in this case "wrap" while placing the component.

To create a project called helloworld run:
stack new helloworld simple
This will create a directory called helloworld with the files necessary for a Stack project.
When building a webserver with Express it's often required to serve a combination of dynamic content and static files.
For example, you may have index.html and script.js which are static files kept in the file system.
It is common to use folder named 'public' to have static files.
In this case th...

I/O in node is asynchronous, so interacting with the disk and network involves passing callbacks to functions. You might be tempted to write code that serves up a file from disk like this:
var http = require('http');
var fs = require('fs');
var server = http.createServer(function (req, res) {
