Usually sub charts of a composite chart share the dimension of the parent. However sometimes, especially when scatter plots are composed, the sub charts may use different dimensions. This example uses two scatter plots both using array dimensions. Typically scatter plots use two dimensional brushing (see scatter brushing); however, composite charts only support one dimensional brushing along the x axis.

Try brushing on the chart and see data getting filtered in the table on the right.

Notice that unlike in other charts, brushing removes points outside range of the brush instead of just fading them. This is because the composite chart uses three different dimensions for the child charts, so each observes the filter applied to the others.
