grMask(CHART_MyChart, grMaskPercent, "99.99%")
grLabel(CHART_MyChart, grShowPercent, True)
grDraw(CHART_MyChart)
Syntax
grMask(<Chart name> , <Type of mask> , <Mask value>)
<Chart name>: Control name or character string
Name of the chart to be used. This name corresponds to:
  • the chart name defined through programming with grCreate.
  • the name of the Chart control in the window, page or report editor.
Android Only Chart controls are available.
PHP Only the interactive Chart controls are available.
<Type of mask>: Numeric constant
Mask used:
grMaskAxisThe specified mask is used to format the values displayed on the chart axes.
Example: Displays the value in the current currency: the value of the mask is "+99,999,999,999.99 $".
grMaskPercentThe specified mask is used to format the percentages displayed in the chart (grLabel(<Chart Name>, grShowPercent, True))
Caution: the % symbol must be found in <Mask Value>.
Example: "99.99%" displays the percentage with 2 digits after the decimal point.
grMaskTimeAxisThe specified mask is used to format the dates or times displayed on the chart axes.
Example: Displays the date in "MM/DD/YYYY" format: the value of the mask is "MM/DD/YYYY".
grMask("MyChart", grMaskTimeAxis, "MM/DD/YYYY")
This constant is supported by the types of charts that can include a time axis: Column, Horizontal column, Line and Area.
Android This constant is not available.
grMaskValueThe specified mask is used to format the values displayed in the chart (grLabel(<Chart Name>, grShowValue, True))
Example: Displays the value in the current currency: the value of the mask is "+99,999,999,999.99 $".
<Mask value>: Character string
Description of the mask to use.
  • For the grMaskValue constant: Empty string ("", default value) to disable the display mask.
  • For the grMaskPercent constant: "99%": default value.
  • For the grMaskTimeAxis constant:
    • If the value to display is a date, it must be in "YYYYMMDD" format. The supported masks are identical to the ones used by DateToString.
    • If the value to display is a time, it must be in "HHMMSSCC" format. The supported masks are identical to the ones used by TimeToString.
The masks are defined via characters: "9", ".", ",", "+", "-" and space characters. For example: "99.999,99". For the currency masks, use up to 17 significant digits for the integer part and 6 for the decimal part. For example: "99 999 999 999 999 999,999999".
Remarks:
  • In order for the number to be filled with zeros on the left, the "0" character must be used on the left of the mask. For example: "099.999,99".
  • To force the signs, use the "+" character on the left. For example: "+9999".
Remarks
This function only affects charts that display values or percentages.
