+ <title>Reports and Charts</title>
+
+ <para>As well as the standard buglist, Bugzilla has two more ways of
+ viewing sets of bugs. These are the reports (which give different
+ views of the current state of the database) and charts (which plot
+ the changes in particular sets of bugs over time.)</para>

+ <title>Reports</title>
+
+ <para>
+ A report is a view of the current state of the bug database.
+ </para>
+
+ <para>
+ You can run either an HTML-table-based report, or a graphical
+ line/pie/bar-chart-based one. The two have different pages to
+ define them, but are close cousins - once you've defined and
+ viewed a report, you can switch between any of the different
+ views of the data at will.
+ </para>
+
+ <para>
+ Both report types are based on the idea of defining a set of bugs
+ using the standard search interface, and then choosing some
+ aspect of that set to plot on the horizontal and/or vertical axes.
+ You can also get a form of 3-dimensional report by choosing to have
+ multiple images or tables.
+ </para>
+
+ <para>
+ So, for example, you could use the search form to choose "all
+ bugs in the WorldControl product", and then plot their severity
+ against their component to see which component had had the largest
+ number of bad bugs reported against it.
+ </para>
+
+ <para>
+ Once you've defined your parameters and hit "Generate Report",
+ you can switch between HTML, CSV, Bar, Line and Pie. (Note: Pie
+ is only available if you didn't define a vertical axis, as pie
+ charts don't have one.) The other controls are fairly self-explanatory;
+ you can change the size of the image if you find text is overwriting
+ other text, or the bars are too thin to see.

+ <title>Charts</title>
+
+ <para>
+ A chart is a view of the state of the bug database over time.
+ </para>
+
+ <para>
+ Bugzilla currently has two charting systems - Old Charts and New
+ Charts. Old Charts have been part of Bugzilla for a long time; they
+ chart each status and resolution for each product, and that's all.
+ They are deprecated, and going away soon - we won't say any more
+ about them.
+ New Charts are the future - they allow you to chart anything you
+ can define as a search.
+ </para>
+
+ <note>
+ <para>
+ Both charting forms require the administrator to set up the
+ data-gathering script. If you can't see any charts, ask them whether
+ they have done so.
+ </para>
+ </note>
+
+ <para>
+ An individual line on a chart is called a data set.
+ All data sets are organised into categories and subcategories. The
+ data sets that Bugzilla defines automatically use the Product name
+ as a Category and Component names as Subcategories, but there is no
+ need for you to follow that naming scheme with your own charts if
+ you don't want to.
+ </para>
+
+ <para>
+ Data sets may be public or private. Everyone sees public data sets in
+ the list, plus any private data sets they are subscribed to. You are
+ automatically subscribed to any data sets you create, but others may
+ subscribe to them too if they know about them. Only administrators can
+ make data sets public.
+ No two data sets, even two private ones, can have the same set of
+ category, subcategory and name. So if you are creating private data
+ sets, one idea is to have the Category be your username.
+ </para>
+
+ <section>
+ <title>Creating Charts</title>
+
+ <para>
+ You create a chart by selecting a number of data sets from the
+ list, and pressing Add To List for each. In the List Of Data Sets
+ To Plot, you can define the label that data set will have in the
+ chart's legend, and also ask Bugzilla to Sum a number of data sets
+ (e.g. you could Sum data sets representing RESOLVED, VERIFIED and
+ CLOSED in a particular product to get a data set representing all
+ the resolved bugs in that product.)
+ </para>
+
+ <para>
+ If you've erroneously added a data set to the list, select it
+ using the checkbox and click Remove. Once you add more than one
+ data set, a "Grand Total" line
+ automatically appears at the bottom of the list. If you don't want
+ this, simply remove it as you would remove any other line.
+ </para>
+
+ <para>
+ You may also choose to plot only over a certain date range, and
+ to cumulate the results - that is, to plot each one using the
+ previous one as a baseline, so the top line gives a sum of all
+ the data sets. It's easier to try than to explain :-)
+ </para>
+
+ <para>
+ Once a data set is in the list, one can also perform certain
+ actions on it.
+ For example, one can Subscribe to or Unsubscribe from a private
+ data set. This is useful if someone else has shown you a chart,
+ and you want to make some of their data sets appear in your list,
+ so you can use them in your own charts. One can also edit the
+ data set's parameters (name, frequency etc.) if it's one you
+ created or if you are an administrator.
+ </para>
+
+ <para>
+ Once you are happy, click Chart This List to see the chart.
+ </para>
+
+ </section>
+
+ <section>
+ <title>Creating New Data Sets</title>
+
+ <para>
+ You may also create new data sets of your own. To do this,
+ click the "create a new data set" link on the Create Chart page.
+ This takes you to a search-like interface where you can define
+ the search that Bugzilla will plot. At the bottom of the page,
+ you choose the category, sub-category and name of your new
+ data set.
+ </para>
+
+ <para>
+ If you have sufficient permissions, you can make the data set public,
+ and reduce the frequency of data collection to less than the default
+ seven days.
