I have a tab control, 3 tabs, and an area chart on each. All displaying different parts of the same data - the x axis is year of life, your age is the first point, your life expectancy is the last point. Once i exceed 72 years in this 'life span' chart , the structured array that is being read from is correct and verifiable via report and table displays from the same array, - the chart stops on the next to last data point, (one year less than life expectancy ) - on 2 of the 3 charts , one shows all the years - the 1st and 3rd skip the last year. I have checked every parameter, every setting , there is no button that says 'read the structured array - but bail out on the last element of the array' lol . Any ideas of things to check ? And i have compared setting to setting - in the chart 2 - which prints all - and charts 1 and 3 - which skip the last one. And this only happens when the points (life span) is >= 72. Thanks in advance.
