Class Plot

java.lang.Object
  hudson.plugins.plot.Plot

All Implemented Interfaces:

Comparable<Plot>

public class Plot
extends Object
implements Comparable<Plot>

Represents the configuration for a single plot. A plot can have one or more data series (lines). Each data series has one data point per build. The x-axis is always the build number. A plot has the following characteristics:

• a title (mandatory)
• y-axis label (defaults to no label)
• one or more data series
• plot group (defaults to no group)
• number of builds to show on the plot (defaults to all)

A plots group effects the way in which plots are displayed. Group names are listed as links on the top-level plot page. The user then clicks on a group and sees the plots that belong to that group.

yaxis

public String yaxis

Y-axis label. Optional.

series

public List<Series> series

List of data series.

group

public String group

Group name that this plot belongs to.

numBuilds

Constructor Detail

Plot

@DataBoundConstructor
public Plot(String title,
                                 String yaxis,
                                 String group,
                                 String numBuilds,

setProject

public void setProject(hudson.model.AbstractProject<?,?> project)

A reference to the project is needed to retrieve the project's root directory where the CSV file is located. Unfortunately, a reference to the project is not available when this object is created.

Parameters:

project - the project

plotGraph

public void plotGraph(org.kohsuke.stapler.StaplerRequest req,
                      org.kohsuke.stapler.StaplerResponse rsp)
               throws IOException

Generates and writes the plot to the response output stream.

Parameters:

req - the incoming request

rsp - the response stream

Throws:

IOException

Parameters:

req - the incoming request

rsp - the response stream

Throws:

IOException

addBuild

public void addBuild(hudson.model.AbstractBuild<?,?> build,
                     PrintStream logger)

Called when a build completes. Adds the finished build to this plot. This method extracts the data for each data series from the build and saves it in the plot's CSV file.
