Namespace: GlobFX.SwiffChartGenerator
Assembly: GlobFX.SwiffChartGenerator (in GlobFX.SwiffChartGenerator.dll)

Set series X and Y values from data encoded in a separator-delimited string (for XY-Scatter and XY-Curves).

Visual Basic

Public Sub SetSeriesXYValuesFromString( index As Integer, values As String )

public void SetSeriesXYValuesFromString( int index, string values );

Arguments

index: An integer value that specifies the zero-based index of the series in the chart object.
values: A a separator-delimited string that specifies the X and Y data. The string must be formatted as follows: x1 y1 x2 y2 ... xn yn.

Remarks

Note: This method is available when manipulating XY data series required for displaying XY-Curves and XY-Scatter. Note that the Chart type (ie: bar, column, line, etc.) is defined in the Swiff Chart style file (.scs) which must be loaded via the LoadStyle method.

You can set both the X and Y values of a specified series in a chart with data encoded in a string (i.e. the values argument). The string must be formatted as a list of pairs of numerical values, two consecutive values must be separated by a separator character that can be specified with the SetSeparators method.

Here is an example of X Y value pairs encoded in a string with the character ";" as separator.

myEncodedString= "1;12;2;7.5;3;11.3;4;9.2;5;5.3"

This encoded string is interpreted as a set of 5 xy-points whose coordinates are (1,12) (2,7.5) (3,11.3) (4,9.2) (5,5.3)

The string argument values is parsed by the chart object according to the separator characters specified to the chart object (see the SetSeparators method for specifying separator characters and rules).

The ";" character is the default separator character.

If the index argument refers to a series that does not exist in the chart object, the series is created.

index must be superior or equal to 0.

Sample Code

The following code shows how to store the XY values of the table below using the SetSeriesXYValuesFromString method. This table has two series named "Year 2006" and "Year 2007". Each of these two series contains independant X values and Y values.

Year 2006		Year 2007
X	Y	X	Y
1	12	1.5	14
2	7.5	1.8	9.9
3	11.3	3.7	13.1
4	9.2	3.9	11.5
5	5.3	5.8	4.9
