[jira] [Created] (FLEX-33816) DateTimeAxis skips labels for
consecutive dates in disabledRanges & disabledDays
Manohar Joshi created FLEX-33816:
------------------------------------
Summary: DateTimeAxis skips labels for consecutive dates in disabledRanges & disabledDays
Key: FLEX-33816
URL: https://issues.apache.org/jira/browse/FLEX-33816
Project: Apache Flex
Issue Type: Bug
Components: Charts
Reporter: Manohar Joshi
Priority: Minor
Steps to reproduce:
-Create a chart with DateTimeAxis with below sample data below.
-Apply dataUnits="weeks"
-Apply disabledDays of [0,6]
-Apply disabledRanges containing say Aug 26, which is Monday.
-So, we have 3 consecutive disabled dates.
Expected result:
Chart to show labels at equal intervals.
Actual result:
Chart will skip a label 8/27, creating a gap.
Workaround (if any):
Modify DateTimeAxis to replace all occurrences of:
i = tmp.time;
by
i = dateSkipOffDays(tmp.time);
Add following functions:
public function dateSkipOffDays(time:Number):Number
{
var pDate:Date = new Date(time);
var holidays:Array = disabledRanges;
if( ! ( isWeekend(pDate) || isHoliday(pDate) ) )
return pDate.time;
else {
pDate.setDate(pDate.getDate() + 1);
return dateSkipOffDays(pDate.time);
}
}
public function isHoliday(pDate:Date):Boolean
{
var holidays:Array = disabledRanges;
if(holidays) {
for(var i:int=0; i<holidays.length; i++){
var date:Date = holidays[i];
var diff:int = dateDiff(date,pDate);
if(diff==0)
return true;
}
}
return false;
}
public static function dateDiff(pStartDate:Date, pEndDate:Date):int
{
var _differenceDays:int=Math.ceil((pEndDate.getTime() - pStartDate.getTime()) / MILLISECONDS_IN_DAY);
return _differenceDays;
}
public function isWeekend(pDate:Date):Boolean
{
if (pDate.day == 0)
{
return true;
}
else if (pDate.day == 6)
{
return true;
}
return false;
}
