Jenkins 2.73.3
Plot Plugin 2.0.0
Pipeline 2.5
I have following configuration on freestyle job which will generate chart successfully.
Then I have pipeline job where I'm using following code which is generated with Snippet Generator using same configurations than in freestyle job:
plot csvFileName: 'plot-14bd9ae9-09b8-407a-8fb5-fffc0528e2c5.csv', exclZero: false, group: 'RX_Module_1', keepRecords: true, logarithmic: false, numBuilds: '', style: 'line', title: 'P1', useDescr: false, xmlSeries: [file: 'plot.xml', nodeType: 'NODESET', url: '', xpath: '*/*/P1/*'], yaxis: '', yaxisMaximum: '', yaxisMinimum: ''
For some reason that code doesn't generate data. Generated csv file looks like this:
"Title","P1"
"Value","Series Label","Build Number","Build Date","URL"
So only topics are there but the data lines are missing totally. I'm using exactly same xml file in both jobs.
[JENKINS-48215] Plot plugin doesn't generate chart data when using pipeline

added a comment - Same issue here with jenkins 2.102 and plugin version 2.0.2 and a similar setup as Jaakko Finning, ie pipeline job, trying to extract data from a xml file.
The csv file for the plot is created with the title and column header, but data points are not added.

The csv file for the plot is created with the title and column header, but data points are not added. yobeone In another pipeline example I actually could successfully create plot data based on XML series (see code example below) => I thus suspect the problem to be in the definition of the xmlSeries parameter: e.g. the file is not found/there, or the xpath expression is invalid or does not match.
This works for me:
plot(group: 'PHPLOC', title: 'Size: Files', csvFileName: 'plot-phploc-files.csv', xmlSeries: [[file: 'phploc.xml', nodeType: 'NODESET', xpath: '/phploc/directories|/phploc/files', url: "${env.JOB_URL}%build%/"]], style: 'line', yaxis: 'Count', keepRecords: false)
Please note the restrictions of the xpath expression and the magic behaviour with respect to Plot plugin and XML Series (see https://github.com/jenkinsci/plot-plugin/blob/master/src/test/java/hudson/plugins/plot/XMLSeriesTest.java)

added a comment - Thank you for pointing this out. My problem was indeed with the xml file that was no longer found.
I guess finding this open blocking request in the issue tracker made me jump to conclusions too quickly.
If anyone else comes to this page, here is a description of what happened : the code generator from jenkins inserted single quotes around the xml filename, which fails to resolve any ${variable} that the file name actually contained. Manually changing these for double quotes made the whole thing work.

added a comment - Based on my experience as well as the comment from yobeone I dare to resolve this issue with "Cannot Reproduce"...

I seem to have the same failure symptom for a scripted pipeline using 'plot' step in the shared library (there is no "Plots" item on the left for the job
– which I correctly get for a very simple declarative pipeline prototype project), but with a significant difference: the aggregated csv file in the root folder of the job actually contains the expected data
=> Is this related or not? Should I file a dedicated issue for that? Or am I missing something?
Update: This is due to JENKINS-28981 (the build always failed – on purpose) so it was not shown => even an unstable build suffices to show the Plots => I am therefore going to upvote JENKINS-28981, as it does not sound right to me...
