This example demonstrates how ChartView can be used to build charts based on data from a database or in-memory source.
|
|
|
|
DB ChartView is directly connected to TDataSource and uses 2 TTable fields as source for categories and series values.
|
|
|
|
In-memory source for Unbound ChartView was created using 4 queries of data from a database: one query for each quarter of the year, defining 4 series.
|
|
|
|
In this demo you can:
|
|
|
|
- choose a Column or Bar diagram to show chart data using the View submenu
|
|
|
|
- change different aspects of the chart's presentation (title, legend, grid lines, captions, etc.) using the View submenu
|
|
|
|
- see how styles and custom draw are used to change the appearance of DB ChartView
|
|
|
|
- see TableView at the Orders level - showing data used to feed both ChartViews
