===Stacked Bar Chart===__NOEDITSECTION__
A stacked bar chart is similar to a grouped bar in that it allows you to represent two different fields on the chart. The key difference is that the stacked bar chart layers the values of the series expression (the field represented in the legend) allowing you to easily compare the categories to one another.

To add a grouped bar chart to the report:
<ol>
<li>Create a report which groups the results by the fields that will be represented on the horizontal axis of the chart.</li>
</ol>
{{note|For a stacked bar chart, you will need to specify at least two groupings.}}
<ol start="2">
<li>Add any variables that you may need to calculate the value that you would like to show on the chart.</li>
<li>If you would like to display the calculated variable for each group, you should add the footer for the field on which the results will be grouped. This footer will be used to display the variable for the group that will subsequently be used in the chart. To add a group footer:</li>
<ol type="a">
<li>From the '''View''' menu, select '''Bands'''.</li>
:The <FileName> bands… window displays.
<li>Select <''GroupFieldName''>Footer from the left pane where ''GroupFieldName'' is the name of the field on which the results will be grouped. For example, if you are creating a report on land and group the results by the priority, the name of the band would be ''priorityFooter''.</li>
<li>In the right pane, enter a numeric value in the '''Band Height''' field. You may adjust the height of the summary</li>
<li>Click the '''Apply''' button.</li>
</ol>
<li>Add a summary section to the report.</li>
<li>Click the [[Image:iRepBarChart.png]] icon.</li>
<li>In the summary section of the report, hold down the mouse button and drag the cursor to form the rectangle which will contain the chart.</li>
