Y-axis

Definition

The y-axis is the vertical line in a two-dimensional graph that represents the range of values for one variable. It is used to plot data points in relation to the x-axis, which runs horizontally.

1. The y-axis typically represents dependent variables in financial data visualizations.
2. In financial graphs, the y-axis can show metrics such as stock prices, interest rates, or revenue over time.
3. Scaling on the y-axis must be consistent to accurately interpret trends and patterns.
4. Y-axes can be logarithmic or linear, affecting how data is visualized and interpreted.
5. Labeling the y-axis clearly with units of measurement is crucial for understanding financial charts.
