histogram plots with many different samples
...this does not exist. The address of the web page is http://www1.maths.lth.se/help/R/plot.histogram/ Unfortunately I could not find any other resource or help.

...after the 0.1-quantile till 0.9-quantile. So as opposed to ecdf the y-axis will be from 0.1 to 0.9 rather than 0 to 1. Or, a way to find the minimum distance between the theoretical gamma distribution and empirical distribution between 0.1 and 0.9 th percentiles.

Lets say (totally hypothetical situation) from a distribution you can generate a continuous random sample between the numbers 0 and 100. but I have data from 20 to
