Study on General Statistic Chart Drawing Based on OWC

The chart based on OWC component is widely favored by the developers, but the researchers mainly focus on the implementation steps, while the data is directly bound with the program. In practice, this approach reduces the reusability of the program, causing a great deal of redundancy. Therefore, generic class of statistical chart based on OWC is developed using C # language, which implements the separation of drawing data and drawing methods. At the same time, using the AJAX technique，multiple requirement is provided according to needs without refreshing the page, which improves the running speed of program.
