`stat`	Chi-square test statistic
`df`	Degree of freedom
`alp`	Level of significance, Default: 0.05
`side`	Type of the alternative hypothesis, Default: 'two'
`pup`	Maximum probability for the range of x-axis, Default: 0.999
`dig`	Number of digits below the decimal point, Default: 4
`ppt`	Number of plot points in the critical region, Default: 20

None.
