The FORMAT_AXIS_VALUES function converts a vector of numeric values into a vector of string values. This routine uses the same rules for formatting as do the axis routines that label tick marks given a set of tick values.
Result = FORMAT_AXIS_VALUES( Values )
Returns a vector of formatted string values from an input vector of numeric values.
Set this argument to a vector of numeric values to be formatted.
None.
Suppose we have a vector of axis values:
axis_values = [7.9, 12.1, 15.3, 19.0]
Convert these values into an array of strings:
new_values = FORMAT_AXIS_VALUES(axis_values)
HELP, new_values
PRINT, new_values
PRINT, axis_values
IDL prints:
NEW_VALUES STRING = Array[4]
7.9 12.1 15.3 19.0
7.90000 12.1000 15.3000 19.0000
