Table Utilities
In order to make it easier for you to visualize tables and create graphs, we've created a few utility functions! The following describe what they do and how they work.
visualize_table(table)
This function takes in a table and displays it! For example, the table:
Fruit | Price |
"apple" | 1.49 |
"orange" | 1.49 |
"peach" | 2.49 |
Can be written as:
Calling visualize_table
on fruit
would produce the following:
bar(table, x, y)
If you want to graph categorical data, you can use the bar
function; it produces a bar graph given a table, the x-axis column, and the y-axis column. If the following table is fruit
:
Fruit | Price |
"apple" | 1.49 |
"orange" | 1.49 |
"peach" | 2.49 |
Calling the bar
function would do the following:
line(table, x, y)
If you want to graph two different kinds of numerical data against each other, you can use the line
function; it produces a line graph given a table, the x-axis column, and the y-axis column. If the following table is population
:
Year | Population |
1900 | 123,432 |
1905 | 126,743 |
1910 | 134,894 |
1915 | 156,483 |
Calling the line
function would do the following:
