Bug: With huge graphs, it is not possible to change the position of the Y axis title by entering a distance in the "TItles and Labels" tab of Format Axis
The third ("Titles and labels") tab of Format Axes lets you position the graph, X-axis and Y-axis titles by specifying the distance from the graph.
Bug in Prism 7 Windows if you make the graph very large by choosing Change..Resize graph, To fill page. In that case, the position of the Y-axis title from the axis is shown as 0.0 and changing that value won't move the title. Will be fixed in 7.03.
To avoid the problem: If you want a huge graph, stretch the axes manually or specify the axes lengths in the first tab of Format Axes.
To fix the problem once it has happened: Use Change..Resize Graph...Smaller
