Explanation
In this example, the IFERROR function is used to trap and suppress the #DIV/0! error that occurs when there is no value for Orders (column D). Without IFERROR, the formula C5/D5 would display a #DIV/0! error in E6 and E9.
The IFERROR function takes two arguments: a value (usually entered as a formula), and a result to display if the formula returns an error. The second argument is only used if the first argument throws an error.
In this case, the first argument is the simple formula for calculating the average order size, which divides total sales by the order count:
=C5/D5
The second argument is entered as an empty string (""). When the formula returns a normal result, the result is displayed. When the formula returns #DIV/0!, an empty string is returned and nothing is displayed.
Explanation
The REPT function simply repeats values. For example, this formula outputs 10 asterisks:
=REPT("*",10) // outputs **********
You can use REPT to repeat any character(s) you like. In this example, we use the CHAR function to output a character with a code of 110. This character, when formatted with the Wingdings font, will output a solid square.
CHAR(110) // square in Wingdings
To calculate the “number of times” for REPT, we scale values in column C by dividing each value by 100.
C11/100 // scale values down
This has the effect of outputting one full square per 100 dollars of sales. Increase or decrease the divisor to suit the data and available space.
Conditional formatting option
You can also use the “data bars” feature in conditional formatting to display an in cell bar.
