If a chart does not have a value field specified, the chart will take a count of records that fall into the row and column group. For example, if the EmployeeID data field in the Orders controller is specified as a row field, then the count of Orders will be used as the value.

Data Field	Tag
EmployeeID	pivot1-row1-bar

The chart data shows that the count of Orders is used as the value.

In order to use a different value for the chart, a value field must be specified. Tag the data field that you wish to use with the correct pivot ID and assign it “val” plus the order for the data field. The example below will use Freight field as a value.

Data Field	Tag
EmployeeID	pivot1-row1-bar
Freight	pivot1-val1

Notice that the values are the same! That is because the value mode of Freight is the default “count”. You must specify a value mode to manipulate the number. The example below will use the sum of Freight by using the keyword “sum”.

Data Field	Tag
EmployeeID	pivot1-row1-bar
Freight	pivot1-val1-sum

The correct sum can be seen in the chart and data.

The table below shows a list of the available value modes.

Keyword	Description
count	The default mode. Will count every record.
sum	Will summate the value in every record in the row/column group.
min	The smallest value in the group.
max	The largest value in the group.
avg	The sum divided by the count.
