Data fields serve as data points on the chart, determining the width of a bar, the height of a column, or the location and size of a bubble. The default data field is the one you originally drag and drop onto the report design surface to create the chart. You can add more data fields and delete them as necessary.
A single data field shows a single chart element (bar, column, bubble, line, or point) for each category in the chart. Multiple data fields show a chart element for each data field in each category, with the name of each data field displayed in the legend.
For example, adding a Max Total attribute to an Invoice bar chart adds a bar showing the maximum total above each Sum Total bar. The legend displays different colors or patterns to differentiate the Sum Total and Max Total bars.
