Sparklines and data bars are small, simple charts that convey information with little extraneous detail in a paginated report. In a paginated report, when you check this option, the values in your sparklines and data bars align across the different cells in the table or matrix. They align even if there are missing values in the data they're based on.
In this image, the column chart shows daily sales for each employee. For days that an employee has no sales, the chart leaves a blank and aligns subsequent days horizontally. It also aligns the charts vertically by making the sizes of the different charts relative to each other. For more information, see Sparklines and data bars (Report Builder).
