Using Keywords with Multiple Y Values

When using chart types with more than one Y value, you can show calculation specific to a Y value in certain keywords. To do this, append the Y value position to the keyword. For example, to show the open, close, high, and low values in a stock chart, use the following string: "#VALY, #VALY2, #VALY3, #VALY4".

Formatting Keywords

Certain keywords allow formatting. To format the output of a keyword, at the end of the keyword, add a standard numeric format string or custom numeric format string encapsulated in curly brackets.

When you use a standard numeric format string, the Chart control uses the regional settings on your system to display the calculated values in the local format (such as the Japanese Yen for currency).

For example:

  • To represent Y values as currency, use "#VAL{C}".

  • To represent positive Y values as dollars with negative values shown as positive dollars encapsulated by parentheses, use "#VAL{$#,##0.00;($#,##0.00)}".

For more information, see Numeric Format Strings.
