This graph type stacks one currency's value on top of another. The value of all investments with the same currency are lumped together. The sum of all the stacked sections is the total portfolio value. This graph shows the relative size of each currency within the portfolio. This is the equivalent of the Currency - Pie Graph drawn versus time. The status bar will be updated with the symbol of the currency currently under the cursor. The date and value pointed to by the cursor will be shown in the bottom right status bar panes. If the cursor is turned off then this date/value will be where the cursor is pointing. If a cursor is on, then the value will be the value of the currency under the cursor on the pointed to date. Adjust a particular investment's currency using the Investment Properties - General Dialog.
Use the option Graphs / Options / Normalize to scale each stack so that the total is 100% on each plotted day. This removes the variation of total portfolio market value from the plotted height, to more easily see the allocation percentages with the portfolio.
When there are too many stack sections to fit in the legend, use the arrow/page/home/end keys to scroll the legend.
Use Options / Colors... to edit the colors of the stacked value graph. The stack segments use the "Pie Slice (1-100)" colors.
