基于ActiveX控件的多坐标轴曲线绘图

从COM技术出发,讨论了如何在VB下开发多坐标轴曲线绘图控件的方法.通过建立控件的分层对象模型,使接口的访问更加清晰,为油气田开发生产中绘制多坐标轴的复杂采油气生产曲线提供了方便、有效的工具,并应用到GIS系统.

The Drawing of Multi-Axis Curves based on ActiveX Control

This paper talks about the method of developing the control of drawing the multi-axis curves under the VB environment at the beginning of discussing the COM technology. By establishing the control's hiberarchy object model, the interface accessing becomes more explicit. A convenient and efficient tool is given for the drawing of complicated gas and oil production curves with multi-axis in the oil recovery and production process. And this control has been applied in a GIS system.
