ChartLabelType class (Gantt)

Represents the predefined label formats for chart time-units including year, halfYear, quarterYear, month, thirdMonth, week, day, hour, minute, and second.

The label field format is "ALT1[<|>ALT2<|>...[<||>COUNT[<||>UNIT]]]" where

ALT defines a HTML label
COUNT specifies the value for the count field
UNIT field indicates the value for the unit field, representing a numeric value of exontrol.UnitEnum

(the parts delimited by [] brackets may miss)

The ALT part of the label supports ex-HTLM tags such as (<b>, <i>, <fgcolor>, ...) and <%DATE%> tags as follows:

(year-patterns)
<%q%>	Date shown as the quarter of the year	1 - 4

The control automatically chooses the best-fitting label.

The following example shows how to define alternate labels for year, month, week, and day time-units:

{
   year:   "<%yy%><|>'<%yy%><|><%yyyy%>",
   month:  "<|><%m1%><|><%m2%><|><%m3%><|><%mmmm%><|><%m3%> '<%yy%><|><%mmmm%> <%yyyy%>",
   week:   "<|><%ww%><|><%m3%> <%d%>, '<%yy%><r><%ww%><|><%mmmm%> <%d%>, <%yyyy%><r><%ww%><||><||>256",
   day:    "<|><%d%><|><%d1%> <%d%><|><%d2%> <%d%><|><%d3%> <%d%><|><%dddd%> <%d%><|><%d3%>, <%m3%> <%d%>, '<%yy%><|><%dddd%>, <%mmmm%> <%d%>, <%yyyy%><||><||>4096",
}

Here, "<%yy%><|>'<%yy%><|><%yyyy%>" means the "year" label will display using either two or four digits depending on available space.
