which way is the best to present data based on depth

I am working on an application that presents data against depth (which starts from 0 or some negative value) and as we go deeper, newer data is captured which corresponds to a larger negative distance from where the first data was shot.

These data are presented in tables and graphs.

Today I suggested to put the newest data (corresponding to deeper locations) in the bottom rows of the table and/or lowest point of the graph (just like rotating a normal graph 90 CW) and keep the focus on the bottom of the table/graphs. If the user needed to check older data they can scroll up. Also, I have seen some of our competitors do this and to me it really looks plausible and makes more sense. I have also seen Geologists print our graphs and hold the papers vertically to interpret the data.

My manager almost laughed at me and said its standard to put the newest data on top and inserting the newest data on the bottom only confuses people! Is there some sort of standard that suggests this?
