0 the line of figures or coordinates that are arranged from top to bottom at the side of a graph or map --
1 a vertical line that forms one side of a coordinate plane (= region formed by two number lines) --
2 the vertical line of figures along the side of a graph: --
A stationary solitary wave is formed at some position, and the y-axis of the cartesian coordinate system is located at its crests, as indicated.
In the graph, x-axis indicates the distance in microns and y-axis fluorescence intensity in arbitrary units.
The fruit index is shown with gray shading, with y-axis ticks indicating increments of five.
The x-axis shows time period and the y-axis shows percent correct in obligatory contexts.
The axis of the first rotation is parallel to the xz-plane and the second rotation is parallel to the y-axis.
Tracking trajectory in y-axis in the first trial.
In terms of the metaphor, the y-axis is energy, and the darkness of the line is the proximity of the particle to the observer.
Changes in the y-axis scale should be noted.
