Tchart Delphi 7 Serial
The DBChart is a data aware graphic version of the TChart component. Our goal in this chapter is to introduce the TDBChart by showing you how to integrate some basic charts into your Delphi ADO based application. TeeChart The DBChart component is a powerful tool for creating database charts and graphs. It is not only powerful, but also complex. We wont be exploring all of its properties and methods, so you'll have to experiment with it to discover all that it is capable of and how it can best suite your needs. By using the DBChart with the charting engine you can quickly make graphs directly for the data in datasets without requiring any code.

We have a TChart on the form and have added a Series to it. We are ready to populate the Series. Let’s type some Delphi code to.
TDBChart connects to any Delphi DataSource. ADO recordsets are natively supported. No additional code is required - or just a little as you'll see. The Chart editor will guide you through the steps to connect to your data - you don't even need to go to the Object Inspector. Prepare Our task will be to create a simple Delphi form with a chart filled with values from a database query.
To follow along, create a Delphi form as follows: 1. Start a a new Delphi Application - one blank form is created by default. Place the next set of components on the form: ADOConnection, ADOQuery, DataSource, DBGrid and a DBChart. Use the Object Inspector to connect ADOQuery with ADOConnection, DBGrid with DataSource with ADOQuery. Set up a link with our demo database (aboutdelphi.mdb) by using the ConnectionString of the ADOConnection component. Select the ADOQuery component and assign the next string to the SQL property: SELECT TOP 5 customer.Company, SUM(orders.itemstotal) AS SumItems, COUNT(orders.orderno) AS NumOrders FROM customer, orders WHERE customer.custno = orders.custno GROUP BY customer. Commando A One Man Army Full Movie Free Download. Company ORDER BY SUM(orders.itemstotal) DESC This query uses two tables: orders and customer. Both tables were imported from the (BDE/Paradox) DBDemos database to our demo (MS Access) database.
This query results in a recordset with only 5 records. The first field is the Company name, the second (SumItems) is a sum of all the orders made by the company and the third field (NumOrders) represents the number of orders that were made by the company. Note that those two tables are linked in a master-detail relationship. Create a persistent list of database fields.
(To invoke the Fields Editor double click the ADOQuery component. By default, the list of fields is empty. Click Add to open a dialog box listing the fields retrieved by the query (Company, NumOrders, SumItems). By default, all fields are selected. Select OK.) Even though you don't need a persistent set of fields to work with a DBChart component - we'll create it now. The reasons will be explained later.
