TimeLine (statcvs)

java.lang.Object
- net.sf.statcvs.reportmodel.TimeLine

```
public class TimeLine
extends java.lang.Object
```
Contains time line data for an integer value. The semantics is that at every data point, the time line's value changed from the previous point's value to the current point's value. Time points may be specified either by an absolute value using addTimePoint, or by a value relative to the previous time point using addChange(java.util.Date, int). If all points are specified using addChange, an initial value must be given using setInitialValue(int).

```
public TimeLine(java.lang.String title,
                java.lang.String rangeLabel)
```
    Creates a new time line.
    
    Parameters:
    
    title - the time line's title
    
    rangeLabel - a range label (axis label) for the values
- Method Detail
  - setInitialValue
```
public void setInitialValue(int initialValue)
```
    Sets the initial value of the time line, that is the value just before the first data point.
    
    Parameters:
    
    initialValue - the time line's initial value
  - addTimePoint
```
public void addTimePoint(java.util.Date date,
                         int value)
```
    Adds a data point to the time line. Data points may be added in any order.
    
    Parameters:
    
    date - the data point's date
    
    value - the data point's value
  - addChange
```
public void addChange(java.util.Date date,
                      int delta)
```
    Specifies that the time line's value changed at a given date. Data points may be added in any order.
    
    Parameters:
    
    date - the data point's date
    
    delta - the value change at this time
  - isEmpty
```
public boolean isEmpty()
```
    Checks if the time series is empty. A series is considered empty if it has zero or one time points. It takes two distinct time points to actually make it a series.
    
    Returns:
    
    true if the time series is empty
  - getDataPoints
```
public java.util.List getDataPoints()
```
    Returns a List of data points, ordered by date.
    
    Returns:
    
    a List of TimePoints
  - getRangeLabel
```
public java.lang.String getRangeLabel()
```
    Returns the range label (axis label) of the values
    
    Returns:
    
    an axis label for the values
  - getTitle
```
public java.lang.String getTitle()
```
    Returns the title of the time line
    
    Returns:
    
    the title
