#573 charts block height on welcome/portal pages

[ggpauly]

Chart blocks are given limited height on the welcome and portal pages. If you want to show a chart on one of these pages you most likely want to show the whole chart.

This patch expands height to height required by the chart without a vertical scroll bar.

This patch was suggested by fisharebest in response to a help forum question.
