横軸

1. Origins, structure, and basic meaning

• Structure: 横軸 is read as よこじく; it combines 横 (horizontal) and 軸 (axis) for the horizontal axis of a graph.
• Basic usage: Use 横軸に時間を記入する for the plotted variable and 横軸の目盛りを十ずつ増やす for tick increments.

2. Common pitfalls and similar expressions

• Axis and variable
  • It commonly corresponds to the x-axis, but its variable depends on the graph; here the horizontal axis carries time.
• Scale increments
  • 十ずつ means successive tick values increase by ten, not that the axis has exactly ten ticks.
