Introduction

Data fields are a very useful tool when translating your database structure to chart data. It allows you to map which column of your data table or query populates a given element property.

ShowSee Illustration

For example, if you have a column which represents certain information you want to use as a tool tip, it can easily be mapped using data fields. The 'DataFields' property of DataEngine and Chart.Series is a string which can be supplied as a comma delimited list of element property, to data column, relationships.

For example, in the following DataFields string

"YValue=Cost,Name=Brand,ToolTip=Description"; Cost, Brand, and Description are all columns in a data table. YValue, Name, and ToolTip are element values.  

Custom tokens can also be used to populate elements with additional database columns which can be used by element tool tips, urls, within labels and so on.

The following table outlines the available element values and shortcuts which can be mapped to your data columns.

Token Name

Description

Name Sets Element.Name
Yvalue Sets Element.YValue or Element.YDateTime depending on the column data type.
YValueStart Sets Element.YValueStart or Element.YDateTimeStart depending on the column data type.
Xvalue Sets Element.XValue or Element.XDateTime depending on the column data type.
XValueStart Sets Element.XValueStart or Element.XDateTimeStart depending on the column data type.
BubbleSize Sets Element.BubbleSize
Complete Sets Element.Complete
Open Sets Element.Open
Close Sets Element.Close
High Sets Element.High
Low Sets Element.Low
Volume Sets Element.Volume
tooltip Sets Element.ToolTip
urltarget Sets Element.URLTarget
Url Sets Element.URL
LabelTemplate Sets Element..LabelTample
Table Specifies the name of the table to use when multiple tables exist, for example when a DataSet is used.

 All Other sets Element.Name. and/or if date it sets Element.XDateTime.

Data fields and XML documents

Xml Documents dont store data exactly as databases do.

Using Data Fields

"[Token]=[Data Column],..."

Escape Character
Some database columns can have characters such as commas ','. In order to reference these column names an escape character can be used.
"YAxis=Tom\,Harry"

The above tables are color coded for reference to which table the column name refers. If there is more than one example in sub sections such as 'Simple Graph', they are equivalent.

ChartType.Combo & ChartType.ComboSideBySide
