dear all,
i am anewcomer. i have a set of paired data, the values are great different from each other. i want to show them in histogram.
first, how to draw each bar for corresponding paired data  side by side;
second, how to set the scale of y axis? one is up to 100-fold to the other. ifdoubleslash  is used to omit some coordinates, the histogram will looks better.
is there anyone that can help me?
