但是大多数简单的曲线绘图仪在绘制二维数据方面或者在复杂的图形中进行极为精细的控制方面显得很不足。
However, most simple curve plotters are insufficient for plotting two-dimensional data or for exerting detailed control over a complicated graph.
无论是对于只有最少代码的“以快捷但不恰当方式获得的”图形，还是对于需要非常细粒度控制的复杂专业图形，JpGraph 都可以使它们的绘制变得简单。
JpGraph makes it easy to draw both "quick and dirty" graphs with a minimum of code and complex professional graphs, which requires a very fine grain control.
