The plotting of data on a graph is used to observe, and subsequently describe, visible patterns that exist within the data.

x - independent, y is dependent
When plotTing data over time, for example: horizontal axis: fish stock and vertical axis: year (1990-2010).
A graph is an image representing a mathematical concept, such as the relationship between a set of linked objects, or that of a set of points and the function operating on those points. A data chart is an image which visually presents the relationship between two data sets, one of which may or may not be a function of the other. There is some overlap, as a particular graph can also be a data chart. For example, a plotting of the parabola defined by the function y=x2 is a graph. A plotting of the variable curve defined by the number of animals in a region vs. the amount of available food is a data chart. And a plotting of the logarithmically-curved line showing how the mass of stars relates to their age could very well be both.
An increment of a graph refers to a small change or step in the values of the graph, often used to analyze trends or behaviors within the data represented. It can be applied to both the x-axis and y-axis, indicating a specific increase or decrease in variable values. In the context of plotting functions or data points, increments help in understanding the rate of change and the overall shape of the graph.
tools for collecting scientific data....one tool for recording,collecting, and analyzing data is a microscope :)))
