Overview

IGWaterfallSeries belongs to a group of category series and it is rendered using a collection of vertical columns that show the difference between consecutive data points. The columns are color coded for distinguishing between positive and negative changes in value. Values are represented on the Y axis (IGNumericYAxis) and categories are displayed on the X axis (IGCategoryXAxis or IGCategoryDateTimeXAxis). The IGWaterfallSeries is similar in appearance to IGRangeColumnSeries but it requires only one numeric value rather than two for each data point.

Multiple series of the IGWaterfallSeries type that share the same X axis are rendered in clusters where each cluster represents a data point. The first series in the series collection of the IGChartView control renders as a column on the left of the cluster. Each successive series gets rendered to the right of the previous series. However, if series do not share the X axis, they are rendered in layers with each successive series rendered in front of the previous one.

Tasks

Properties

negativeBrush

Specifies the brush used to color the negative sections of data. When this property is set, all negative data will be colored with the specified brush.

Series.h

radiusX

Determines the x component of the rounded rectangle corners. The default value is 0. When set to 0, the corners will not be rounded. The minimum value for this property should be 0. The maximum value has no upper bound, but will have no effect after the corner has attained its most circular shape and depends on the size of the column.

radiusY

Determines the y component of the rounded rectangle corners. The default value is 0. When set to 0, the corners will not be rounded. The minimum value for this property should be 0. The maximum value has no upper bound, but will have no effect after the corner has attained its most circular shape and depends on the size of the column.
