[Solved] chart line

Hi, I have a Calc sheet on which I have three charts, see attached. Two of the charts are fine, Growth Units and Moderate Units; however the Total Value chart goes haywire after line 137. In the Data Range box if I enter line (cell) 137 as the last value the line plots each data point correctly, but if 138 or greater is the last value the line "flattens out" dramatically. Hope someone can help.
I wrote above that the Growth Units chart was fine, but actually it has a glitch as well. In the centre of the chart the numbers 1.7064 and 14089 appear, I'm not sure where they came from, although 1.7064 is the value in cell D101, perhaps 14089 has something to do with the date in that line? If you click in the centre of the chart the numbers go away.
Thanks, Chuck
