Creating a dll about drawing pie and ba

Project Description: Creating a dll about drawing pie and bar chart for a web application Subject: Graphics Component Design Explanations: 1. This component will be a Microsoft .NET Class Library project. (C# could be.) For aim of project , It can be used in web based applications. (Asp.Net can be) 2. Kinds of Graphics a. Bar b. Pİe 3. Methods a. DataBind () b. ExportChartImage([login to view URL] format, string filePathName) 4. Features; a. Kinds of Graphic (ChartType) b. Maximum data row number (TopNCount) i. Some of the results from data sources, may not be appropriate to show on the graph. For example, a shopping-store sales statistics based on the product are required to be displayed graphically. The data obtained; Product Sales Volume (Units) 1. Product A 100 2. Product B 110 ... [login to view URL] J 80 ... ... ... [login to view URL] N 9 There are 55 on the proper display of the product for a graphic, graphics must be larger and the installation of the image may be slow. In addition, the chart is also hard to interpret. As a solution to the other, in the case of a small graphic image on the display is not possible to interpret. Similar results TopNCount feature for the programmer uses; [login to view URL] = 10; products that shown in graphic; Ürün D, Ürün C, Ürün B, Ürün A, ..... Ürün J and Others will be.. Others, 10 Is the sum of all future product lines. 5. Example of usage; //Creation of the object; YazLabChart myChart = new YazLabChart (); //Datasource appointment //myDataSource >>can be DataSet, DataTable, ArrayList and Array. SQL [login to view URL] = myDataSource; // Determining the type of graphics; [login to view URL] = [login to view URL]; [login to view URL] = [login to view URL]; // Maximum data row number [login to view URL] = 10; //to Print to screen [login to view URL] (); //in order to save [login to view URL]([login to view URL], ”sample”); // Png extension and then download the file can be created on the server. Example code is given below. [login to view URL] fs = [login to view URL]([login to view URL](“[login to view URL]”), [login to view URL]); byte[] btFile = new byte[[login to view URL]]; [login to view URL](btFile, 0, [login to view URL]([login to view URL])); [login to view URL](); [login to view URL]("Content-disposition", "attachment; filename=”[login to view URL]"); [login to view URL] = "application/octet-stream"; [login to view URL](btFile); [login to view URL](); Important notes: 1. The data source type will be left to the user. DataSet, DataTable, Array List, or the structures must be supported. 2. No way, closed or open source libraries and components ready to be used. 3. The project is expected from you in a library. In other words, you develop a library, will be used in different web applications. codes and a sample web application using the library, this library will be held. (urgent project)
