SUMMARY

The discussion clarifies the distinction between 'Raw Data' and 'Diff Raw Data' in data visualization. 'Raw Data' refers to unprocessed information plotted directly on a graph, while 'Diff Raw Data' represents the differences between consecutive data points in the raw dataset. Additionally, the conversation touches on the concept of 'Log Data' and 'Diff Log Data', where the latter indicates the differences in the logarithmic transformation of the original dataset. The user seeks clarity on the methodology for deriving 'Diff Data' from the initial graphs.

PREREQUISITES
  • Understanding of data visualization concepts
  • Familiarity with graphing tools (e.g., Matplotlib, Excel)
  • Knowledge of logarithmic transformations
  • Basic statistics, particularly difference calculations
NEXT STEPS
  • Research how to calculate differences in datasets using Python's NumPy
  • Explore data visualization techniques with Matplotlib
  • Learn about logarithmic transformations in data analysis
  • Investigate best practices for presenting raw vs. derived data in graphs
USEFUL FOR

Data analysts, statisticians, and anyone involved in data visualization and interpretation will benefit from this discussion.

Difference Between 'Raw Data' and 'Difference Raw Data'

I have a whole bunch of information and it's plotted on a graph.

The first graph is the raw data plotted, no transformations done to the data, it is raw.
The second graph is the same data but it says 'Diff Raw Data'
The second graph looks similar but you can tell it's different

The same applies for another graph of the data, but it's the log of the points, this graph is just the log of the points, no alterations
The second graph is the 'Diff Log Data'
again, the second graph looks simliar but you can tell it's different

Does anyone know how what 'Diff Data' means and how they get it from the first graph? The explanation doesn't refer to how they got the second graphs of Diff Data and I am just confused and have understanding of this.

Thank You

I think you are being to vague. You never mention what you are even using to graph with.
 
I figured it out. yea, I was being to vague. Thanks.
