- Reports - To be written + Reports and Charts + + 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.) + +
+ Reports + + + A report is a view of the current state of the bug database. + + + + 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. + + + + 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. + + + + 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. + + + + 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. + + +
+ +
+ Charts + + + A chart is a view of the state of the bug database over time. + + + + 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. + + + + + 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. + + + + + 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. + + + + 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. + + +
+ Creating Charts + + + 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.) + + + + 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. + + + + 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 :-) + + + + 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. + + + + Once you are happy, click Chart This List to see the chart. + + +
+ +
+ Creating New Data Sets + + + 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. + + + + 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. + +
