The combing method of Fortran and Excel to draw graphs is valuable and emphatic. For drawing several graphical sheets with several graphs, this method is particularly suitable. Some suggestions for executing this method are presented, graphical results of nowhere differentiable continuous function are shown. Key words ：Fortran programming; Microsoft Excel software; graphic curves; nowhere differentiable continuous function; computer drawing 供数据源的作用。为此，编程中需设定一个输出数据的文件， 0 引 言 ( 为Excel 调用。如在无处可微连续函数 nowhere differentiable 由编程获得数值计算和数值模拟的结果之后，往往需将 continuous function) 的计算与图示研究中，可用F
