Bug ID 8701
Summary I/O Graph: exported data wrong
Classification Unclassified
Product Wireshark
Version 1.8.7
Hardware x86
OS Windows 7
Status UNCONFIRMED
Severity Major
Priority Low
Component Wireshark
Assignee bugzilla-admin@wireshark.org
Reporter macbeth1650@gmail.com 

Created attachment 10811 [details]
2 single export efforts (reforted from native CSV only with Excel's
text-to-data feature)

Build Information:

--
in the IO Graphs window, I have 5 plot lines configured:
L1:  (unfiltered)
L2:  cpha or edp or browser or bootp
L3:  arp
L4:  tcp
L5:  icmp

The plot looks OK -- nothing irregular, evey line seems to have its own life,
varying as I move through different files in a fileset.

At first, when I clicked the copy button and pasteed into MS Excel, everything
seems OK.  I've checked the data in excel and (per timestamp) L1 - L2 - L3 - L4
- L5 = 0, as expected.

Working through the 10MB/file fileset, I got ~17k lines exported OK.
Somewhere along the line, though, I noticed the following in each exported
line:
L1 = L3 = L4

This does not seem to reproduce at consistent points in the wireshark
experience -- Significantly, you don't need to export 17,000 data points to get
here.  In fact, the badness happened this morning in a fresh Wireshark session
on a freshly rebooted machine.
I saw the badness, then tried to reproduce 2x and succeeded the 1st time but
not the second.  I tried both attempts with .pcap where I had previously
observed the problem.

I'll try attaching examples.
