Optional Forecasted Dates and Bar
Now in addition to the planned and actual dates and timeline bars, you can provide a set of forecasted task dates and display the corresponding timeline bar. This forecasted date is typically used in a project timeline when an original planned task slips or starts early. For example, when you originally plan your project you set planned start and end dates for each task. During the progression of the project some tasks may not actually begin or end according to the plan, but you dont want to change the planned timeline -- you want to keep those dates as a baseline. Thats when the forecasted dates come in. You set those dates to the new start and end times for the task, leaving the original planned dates as-is. Note that implementation of this functionality has caused the structure of the wgDataArray to change. Additionally you may want to check out the wgForecastColor and wgForecastImage properties that let you format the forecasted timeline bars. One more note -- the wgShowBars property has been slightly modified to support the new forecasted timeline bar. you can free download PCS WebGantt 4.0 now.
