Having accurate and elegant titles and other labels on your charts makes a big difference to their overall appearance.
Greek letters, symbols, subscript, and superscript: It's difficult to avoid some kind of "special" character in many equations. While it's easy enough to put the symbols in the data on the spreadsheet, it can be very tricky to get the characters to show up on charts.
Once you have mastered getting special characters onto charts, you'll be able to produce professional-looking charts with accurate labels and you'll never look back. These characters are all available from the Insert menu, Symbol command.
You need to use the Unicode equivalent of the character you want to get to appear on the chart label. You'll see exactly how to do this in the practice session at the end of the lesson.
Unicode is a character encoding standard where many symbols and letters in various languages are identified by a numeric code.
Note You may be used to using the Symbol font, where a is displayed as α, and so on. But using the Insert, Symbol method is a much better solution because Unicode is supported in the text boxes for titles and labels on charts, while the Symbol font isn't.
