+    <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>
+    
+    <section id="reports">
+      <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.
+      </para>

+      <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.

+        <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.
