I am currently working with boxplots charts on JMP : and would like to personalize the design of the plot. Would you know how to set the middle box ( the part without whiskers) to 90% of the data, each whisker representing 5% of the data ?
You can change from an outlier box plot to a quantile box plot. The boxes on both still contain the 25th and 75th percentiles, but the quantile box plot has the 90th and 10th percentiles on the whiskers. I do not believe you can change the box parameters.
