#: 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 below, the Series Expression will be the same as the Category expression.
#:[[Image:iRep30.png|center|500px|''Figure 30. Bar chart –Single attribute y-axis'']]<div align="center">''Figure 30. Bar chart –Single attribute y-axis''</div>
#*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 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 land which block water access (red) vs. those that do not block the water (blue).

#* '''Finally, the Series value can be left blank if desired.'''
# The next step is to provide the correct data for the chart to use. Bar charts require a '''category expression''' and a '''value expression''' where the value expression is a field to group the data by (i.e. the names of the X axis) and value expression is the value to sum.
