Gradient fields are much simpler than charts. They are mainly useful as a background feature to make other fields stand out.
The following image shows a report that uses gradient fields over the labels in the Group Header section:

To create a similar gradient field, complete the following steps:
-
In Design mode of the Designer, select the Add Gradient Field button
from the Fields group in the Design tab.
-
Move your mouse cursor (which has changed to a cross-hair) over the labels in the Group Header section and drag the field to the desired size.
-
To ensure that the field is behind the labels, right-click the gradient field and select Send To Back.
-
Then set the Gradient.ColorFrom and Gradient.ColorTo properties to SteelBlue and White, respectively.
Note: You may change the angle of the gradient field by setting the Gradient.Angle property another value (default value is 0).
