Getting vertical gridlines to appear in line plot in matplotlib
...
You may need to give boolean arg in your calls, e.g. use ax.yaxis.grid(True) instead of ax.yaxis.grid(). Additionally, since you are using both of them you can combine into ax.grid, which works on both, rather than doing it once for each dimension.
ax = plt.gca()

What is a patch in git version control?
...updates text files according to instructions contained in a separate file, called a patch file.
So, in other words it may mean the file with instructions or a program that processes that file and applies it to something.

remove objects from array by object property
... i++) {
var obj = arrayOfObjects[i];
if (listToDelete.indexOf(obj.id) !== -1) {
arrayOfObjects.splice(i, 1);

All you need to do to fix the bug is decrement i for the next time around, then (and looping backwards is also an option):
for (var i = 0; i < arrayOfObjects.le...
Web API Routing - api/{controller}/{action}/{id} “dysfunctions” api/{controller}/{id}

Add an named action to your "DefaultApi" to...
What does it mean to hydrate an object?
...n you probably don't need to deal with hydration explicitly. You would typically use deserialization instead so you can write less code. Some data access APIs don't give you this option, and in those cases you'd also have to explicitly call the hydration step yourself.

good.
LinearLayout.LayoutParams is a subclass of LinearLayout.Marg...

By doing this, you are pr...
