xvalues

Xvalues is a term used to describe the set or sequence of x-values, typically the independent variable or abscissas in a dataset, plot, or mathematical relation. In practice, xvalues are the numerical values placed along the horizontal axis in graphs and charts.

In mathematics, an x-value is a member of the domain when considering a function y = f(x). The collection of all possible x-values forms the function's domain; given a relation, the projection onto the x-axis yields x-values.

In data analysis and statistics, x-values represent predictor or input variables in models, with the corresponding y-values representing outcomes or responses. When plotting scatter plots, x-values are plotted on the horizontal axis and paired with y-values.

In computing and programming, xvalues may appear as an array, list, or column of numbers that stores the horizontal coordinates for charting or geometric computations. Functions or methods may return xvalues as part of a data structure, such as xvalues: [1, 2, 3].

Etymology and usage: The term derives from the variable x, commonly representing the independent variable. In formal mathematics, the term x-values is often hyphenated as x-values; in software or informal writing, it may appear as xvalues.
