<li>The '''Label Expression''' field contains the expression that is used to determine the label for the segment of the pie chart. Because this expression will most likely be the same as the one used in the '''Key Expression''', you can copy the expression from the Key Expression field and paste it into the '''Label Expression''' field.</li>
<li>[[:Image:iRep27.png|Figure 27]] The following figure is an example of the Chart Properties window for a report that contains a pie chart which graphs the total area size of lands based on their priority.</li>

Below ([[:Image:iRep28.png|Figure 28]]) is an example of a report template that totals the area size of lands by priority.

The resulting report pages are shown in [[:Image:iRep29.png|Figure 29]]below.

The expression that you enter in the Series Expression field will vary based on how you want the horizontal axis to appear:
*If you would like the horizontal axis of the bar chart to reflect a single attribute such as the chart displayed in [[:Image:iRep30.png|Figure 30]]below, the Series Expression will be the same as the Category expression.
</ol>
<ol>
*If you would like the horizontal axis of the bar chart to reflect the values of an additional attribute, the Series Expression would be the expression for the secondary level of detail. In the example shown in [[:Image:iRep31.png|Figure 31]]below, the x-axis reflects the land priorities (e.g., Low, Medium, or High). In addition to displaying the priority, the bars of the chart use a different colour to reflect those lands which block water access (red) vs. those that do not block the water (blue).
</ol>
<ol>
The Chart Properties window for this bar chart is shown below (Figure 32). Notice that the series expression and category expression differ.

*If you selected one of the stacked bar chart options, the series expression will be used to determine the segments of each bar. In [[:Image:iRep33.png|Figure 33]]the following figure, the series expression creates red and blue segments in each bar to indicate whether or not water access is blocked.
