Method Detail

isHidden

public boolean isHidden()

Specifies if the selected DataUnit is a Hidden Value

• Java

• DataUnit du;
  du = new DataUnit();
  boolean duIsHidden;
  duIsHidden = du.getIsHidden();
  

dateToDouble

public double dateToDouble(DataUnit d)

Converts the value of the specified DateTime to a Double.

This method is useful when trying to plot on a numerical axis set to Date format.

To convert December 25th, 2012 into a double.

• Java

• double xmasDay;
  xmasDay = DataUnit.DateToDouble(new SfxNET.System.DateTime(2012, 12, 25).StructClone());
  

Parameters:

d -

dateToDouble

public static double dateToDouble(java.util.Date d)

Converts the value of the specified DateTime to a Double.

This method is useful when trying to plot on a numerical axis set to Date format.

To convert December 25th, 2012 into a double.

• Java

• double xmasDay;
  xmasDay = DataUnit.DateToDouble(new SfxNET.System.DateTime(2012, 12, 25).StructClone());
  

Parameters:

d - DateTime to be converted.

doubleToDate

public static java.util.Date doubleToDate(double d)

Converts the value of the specified Double to a DateTime.

This method is useful when dealing with data from a numerical axis set to Date format.

To convert a double to DateTime:

Parameters:

d - Double to be converted.

doubleToTimeSpan

public static TimeSpan doubleToTimeSpan(double d)

Converts the value of the specified Double to a TimeSpan

This method is useful when dealing with data from a numerical axis set to Date format.

To convert a double to TimeSpan:

Parameters:

d - Double to be converted.

isValueHidden

public static boolean isValueHidden(double d)

Determines if a specified value is set as hidden.

This method will return true if the value passed as parameter is set as hidden.

For example, we use this piece of code to display a chart with 4 points, in which 1 of them is hidden:

• Java

• chart1.getData().setSeries(1);
  chart1.getData().setPoints(4);
  chart1.getData().set(0, 0, ((DataUnit)1));
  chart1.getData().set(0, 1, ((DataUnit)2));
  chart1.getData().set(0, 2, ((DataUnit)Chart.HIDDEN));
  chart1.getData().set(0, 3, ((DataUnit)3));
  

The code below will return true:

• Java

• boolean isHidden;
  isHidden = DataUnit.IsValueHidden(DataUnit.op_Implicit(chart1.getData().get(0, 2)));
  

While the following core will return false:

• Java

• boolean isHidden;
  isHidden = DataUnit.IsValueHidden(DataUnit.op_Implicit(chart1.getData().get(0, 1)));
  

Parameters:

d -

timeSpanToDouble

public static double timeSpanToDouble(TimeSpan t)

Converts the value of the specified TimeSpan to a Double.

This method is useful when trying to plot on a numerical axis set to Date format.

To convert a TimeSpan of 90 minutes to double:

Parameters:

t - TimeSpan to be converted.

timeSpanToDouble

public double timeSpanToDouble(DataUnit t)

Converts the value of the specified TimeSpan to a Double.

This method is useful when trying to plot on a numerical axis set to Date format.

To convert a TimeSpan of 90 minutes to double:
