ASCII Charts (Part 2: Bar Chart)

Published by zatoichi49 in

Given an object containing quarterly sales values for a year, return a string representing a bar chart of the sales by quarter.

  • Quarter names (Q1, Q2, Q3, Q4) should appear on the left.
  • Quarters should be sorted in descending order by value.
  • Quarters with the same value should be shown in their yearly order (Q1 -> Q4).
  • Bars should begin with a "|".
  • Repeat the character "#" to fill the bar, with each character having a value of 50.
  • A single space comes after the bar, then the sales for that quarter.
  • If the value is 0, there should be no space after "|".
  • Use the newline character ("\n") to separate each bar in the chart.

Example #1

barChart({Q4: 250, Q1: 300, Q2: 150, Q3: 0})
➞ "Q1|###### 300\nQ4|##### 250\nQ2|### 150\nQ3|0"

When printed:

Q1|###### 300
Q4|##### 250
Q2|### 150
Q3|0

Example #2

barChart({Q4: 500, Q3: 100, Q2: 100, Q1: 150})
➞ "Q4|########## 500\nQ1|### 150\nQ2|## 100\nQ3|## 100"

When printed:

Q4|########## 500
Q1|### 150
Q2|## 100
Q3|## 100

Notes

There should be no additional whitespace after each value.
