f_strLeft(string, int) Function returning the leftmost `_n` characters in `_str`.
Parameters:
string : _str: source string.
int : _n : number of leftmost characters to return.
f_strRight(string, int) Function returning the rightmost `_n` characters in `_str`.
Parameters:
string : _str: source string.
int : _n : number of rightmost characters to return.
f_strMid(string, int, int) Function returning the substring of `_str` from character position `_from` to `_to` inclusively.
Parameters:
string : _str : source string.
int : _from: left character position. The first character's position is 0.
int : _to : right character position.
f_strLeftOf(string, string) Function returning the sub-string of `_str` to the left of the `_of` separating character.
Parameters:
string : _str: string to separate.
string : _op : separator character.
f_strRightOf(string, string) Function returning the sub-string of `_str` to the right of the `_of` separating character.
Parameters:
string : _str: string to separate.
string : _op : separator character.
f_strCharPos(string, string) Function returning the position of the first occurrence of `_chr` in `_str`, where the first character position is 0. Returns -1 if the character is not found.
Parameters:
string : _str: string to search.
string : _chr: character to search for in `_str`.
f_strReplace(string, int, string) Function that replaces a character at position `_pos` in the `_src` string with the `_str` character or string.
Parameters:
string : _src : source string.
int : _pos : position of character to be replaced. The first character's position is 0.
string : _str : replacement character or string.
f_tickFormat() Function returning a format string usable with `tostring()` to round a value to the symbol's tick precision.
f_tostringPad(float, string) Function returning a string representation of a numeric `_val` using a special `_fmt` string allowing all strings to be of the same width, to help align columns of values.
Parameters:
float : _val: string to separate.
string : _fmt: formatting string similar to those used in the `tostring()` format string, with "?" used to indicate padding,
f_print() Function prints a label on dataset's last bar.
