Abstract
We demonstrate an example of visualization process of linguistic data with a combination of a scientific plotting software (Gnuplot) and a graphics editor (Adobe Illustrator).This paper consists of two parts. In the first part, we explain how to use Gnuplot through constructing a line chart and fitting a binomial distribution to data points. In the second part, we use Adobe Illustrator to make a graph more visible. We can change the size of graph, the width of lines, and the text of axis labels and graph legends. Moreover, we insert a TeX-based expression image made by TeXclip into the graph with an arrow that points the solid line corresponding to the expression.
