- 1 -- Introduction
- -----------------
-
- With Delphi 3 and 4 the TDataSet component is completely abstract.
- That means everything important is VIRTUAL, and, more important,
- the TDataSet component does not need the BDE (Borland Database
- Engine).
-
- With some work it's possible to create derived TDataSet components
- to suite your needs or to extend the Delphi database architecture.
-
- The TSeriesDataSet component is an example of reusing the
- TDataSet for an specific case.
-
- 2 -- Explanation
- ------------------
-
- What's it for ?
-
- The TSeriesDataSet will provide you all data values on a Series
- component.
- You can connect a standard TDataSource, TDBGrid and any other
- suitable DB component to it.
-
- This is very useful to show or edit the Series data values as
- if the Series was connected to a Table.
-
-
- 3 -- Testing
- ------------------
-
- When you install TeeChart-Pro, you'll find the TSeriesDataSet
- component located at the "TeeChart" tab on Delphi's component
- palette.
-
- Drop it on a Form, set the Series property to any existing
- Series in your Charts, and set the Active property to True.
-
- That's it !
-
- Now you can drop a TDataSource and a TDBGrid components and
- connect them as usually.
-
- As soon you add point values to the Chart Series, the SeriesDataSet
- will refresh the DBGrid, and vice-versa.
-
- 4 -- Additional information
- ----------------------------
-
- See the included DEMO1 and DEMO2 example projects for
- an example of TSeriesDataSet.
-
- Delphi 3 and 4 come with an example of a virtual DataSet
- for component writers.
-
- You can find this example at:
