Excel has a repeat function called REPT that will repeat a text character any number of times. It’s format is REPT(TEXT, Value) where Value is the number of times that TEXT is repeated. You can use “i”, “o”, “-“, or any other letters/symbols as your text and do a primative bar graph. You can also your numbers to roman numerals if they are less than 4000 by using the ROMAN function. The example table below shows three columns A, B, and C. Row 7 shows the formulae starting with cell A7. The rest of the rows show values if they formulae are copied down.
