StackedBar100% Chart Type

Overview

A stacked bar chart displays multiple series stacked on top of each another horizontally. Using a stacked bar chart is an effective way to present the absolute values of data points represented by the segments of each bar, as well as the total value represented by data points from each series stacked in a bar.

Creating the Stack Bar 100% Chart

In order to create a stack bar chart you will needed to create two instances of chart series, set ChartType of those series as StackedBar100 and fill series with some data, like in the following sample:
