Create Graphical Reports

Graphical reports are one way to view the current state of the bug database. You can run reports either through an HTML table or graphical line/pie/bar-chart-based one. The idea behind graphical report in Bugzilla is to define a set of bugs using the standard search interface and then choosing some aspect of that set to plot on the horizontal and vertical axes. You can also get a 3-dimensional report by choosing the option of “Multiple Pages”.

Reports are helpful in many ways, for instance if you want to know which component has the largest number of bad bugs reported against it. In order to represent that in the graph, you can select severity on X-axis and component on Y-axis, and then click on generate report. It will generate a report with crucial information.

The graph below shows the Bar chart representation for the Bugs severity in component “Widget Gears”. In the graph below, the most severe bug or blockers in components are 88 while bugs with normal severity is at top with 667 number.

Likewise, we will also see the line graph for %complete Vs Deadline

Step 1) To view your report in a graphical presentation,

  • Click on Report from Main Menu
  • Click on the Graphical reports from the given option

Step 2) Let’s create a graph of % Complete Vs Deadline

In here on the vertical axis we chose % Complete and on our horizontal axis we chose Deadline. This will give the graph of amount of work done in percentage against the set-deadline.

Now, set various option to present reports graphically

  1. Vertical Axis
  2. Horizontal Axis
  3. Multiple Images
  4. Format- Line graph, Bar chart or Pie chart
  5. Plot data set
  6. Classify your bug
  7. Classify your product
  8. Classify your component
  9. Classify bug status
  10. Select resolution
  11. Click on generate report

The image of the graph will appear somewhat like this
