Ethereal-dev: [Ethereal-dev] [PATCH] io_stat.c: Fix for bug 714

Note: This archive is from the project's previous web site, ethereal.com. This list is no longer active.

From: "Bill Meier" <wmeier@xxxxxxxxxxx>

Problem:  (reported as bug 714)
          IO-Stats graph 'impulse' and 'filled bar' off-scale values
          sometimes not graphed.
          (These values should aways be displayed (truncated to selected
          max y value).

Solution: Apply "line segment completely off-scale ?" test only for
          line-style charts.


The attached patch corrects the problem.

Bill Meier
