$1\mathrm{.}14$ LAB: Line charts

Instructor note:

In the case of this example, the user needs to assume that the "input" is equivalent to the 'day' value used in to sub$-$set tgt$-$vol in the code below

How does one know how to subset for first $19$ days of data? tgt$[-19],$ I can't figure out why doing what the book says tgt$[0$:$19]$ does not work

How does one know to use $[[$day$],$ double brackets? See section $1\mathrm{.}4\mathrm{.}1,$ selecting Rows and Columns combined with the iloc function section $1\mathrm{.}4\mathrm{.}2$

How do you rotate the $x-$axis labels? $-$ plt $x$ ticks$($rotation$=).$ Found this on the Stackoverflow website.

Write a program that subsets the loads and subsets the stock market data in target.csv$.$

Load the the data from target.csv as target.

Create a new data frame, tgLmarch, by subsetting the last $19$ days of the target data frame.

Create a new data frame, tgLvol, by subsetting the Date and Volume columns.

Create a new data frame, tgLclose, by subsetting the Date and Close columns.

Using the template from this link, create separate line charts for Volume and Close.

If the input is:

$3$

The output is:
