I am also having this same issue. I cannot override past that "maximum number". I know the graph will show data that goes above the 2147483 max. I have a graph that shows the max currently @8,000,000 but it ill not let me override the values to display an additional value axis UNLESS i input fake data. However, that changes the size of the overall graphic!
