<Type of mask>: Numeric constant

Mask used:
grMaskAxis The specified mask is used to format the values displayed on the chart axes.

grMaskTimeAxis The 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".

CHART_MyChart.Mask(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.
This constant is not available.
grMaskPercent The 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.
grMaskValue The 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 (with quotes)

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.
Versions 21 and later
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 <Date type>.ToString.
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.
New in version 21

If the value to display is a date, it must be in "YYYYMMDD" format. The supported masks are identical to the ones used by <Date type>.ToString.
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".
