I have some large time values, seconds to minutes of time expressed in nanoseconds-so at least 9 digits. When I plot some value v. time, the x axis is automatically switched a smaller number and a power. I might have 1.455 1.455 1.455 x10^8 instead of 145500000, 145500001, 145500002. How can I make it display the whole number without a power?
Secondly, since they will take up more room, is there a way to angle them at the tick marks?

set the axis xticklabel to a cell array of strings that are the displays you want.

I have multiple plots with multiple data sets. Would I need to manually find the minimum and maximum x values in each plot so I can create this cell array, or can I just create a large one from 0 to a large number that will always cover any values I could have? How do I associate a tick mark with a corresponding value in the cell array? Can you elaborate a bit more? Thanks

It's better if you determine your ticks
nticks=5; % number of ticks
ticks=linspace(min(x),max(x),nticks)

curticks = get(gca, 'XTick');
set( gca, 'XTickLabel', cellstr( num2str(curticks(:), '%d') ) );
