Charts with Perl - jmetergraph.pl
Hi,
I'm attempting to use the jmetergraph.pl located on the apache
wiki<http://wiki.apache.org/jakarta-jmeter/LogAnalysis> and
I'm having an issue with the "entire_throughput.png" and "entire_users.png"
graph. The charts are created though no data points are shown. The
"ChartStacked.png", "ChartStackedPct.png" and the individual request .png's
are created
successfully.
Errors on script execution:
Use of uninitialized value $d_max in numeric gt (>) at
C:/strawberry/perl/site/lib/Chart/Base.pm line 1529.
Use of uninitialized value $d_min in numeric gt (>) at
C:/strawberry/perl/site/lib/Chart/Base.pm line 1529.
Use of uninitialized value $d_min in subtraction (-) at
C:/strawberry/perl/site/lib/Chart/Base.pm line 1535.
Use of uninitialized value $d_max in subtraction (-) at
C:/strawberry/perl/site/lib/Chart/Base.pm line 1535.
Use of uninitialized value $d_max in multiplication (*) at
C:/strawberry/perl/site/lib/Chart/Base.pm line 1430
Environment setup
Jmeter 2.3.4 r785646 (Agg report setup as per wiki)
Strawberry Perl 5.10.0 MsWin32x86 - Current 31/08/09
Perl Chart 2.4.1
Anyone have any luck getting this to run?

A patch has just been posted to the LogAnalysis page - see the very end:

Sorry, should have added that the bug is triggered by a problem in the
calling program.
For some reason the jmetergraph.pl script is not giving the Chart
package the correct (any) data.

Looks like a bug in the Chart package.
AFAICT, the code fails to handle empty data sets nicely.
At present the code just continues, but it should really raise an
error so that the calling code can be identified and the problem
fixed.
