Hi Kevin,

The Waterfall chart is not available as an "out of the box" feature, but it is possible to display it with a Floating Bar series. As for the horizontal lines - you can use a Line series or a custom series. The only tricky part is aligning the X coordinates of the lines with the vertical edges of the bars, but since the X axis is categorical it shouldn't be a big problem too. Please let us know if you need help with this.
