With this graphing option selected the graphs will show how the value of the investment changed with time. The vertical axis represents this value. The horizontal axis displays the date. If auto scaling is on the vertical axis automatically scales to cover from the minimum to the maximum value achieved during the displayed period. The legend displays the value of the investment on the ending date of the graph, as well as the change from the previous day in parenthesis. The legend will not be displayed when the number of displays is 9.
If the yields are turned on (View / Yields) they will be displayed above the graphs. See Yield Calculations for information on the reported yields.
