同时还启用了基本的等高线和隐线消除特性，最终的绘图是利用splot命令使用数学库内部的函数来创建的。

The base contour is enabled along with hidden line removal, and the sinc plot is created with the splot command using the internally available math library functions.

下面是一个简单的gnuplot例子，它给出了一个具有等高线和隐线消除的3 - D图形。

Here's a short gnuplot example that illustrates 3-d function plotting with contours and hidden line removal.
