What is the meaning of Y-axis in english?

Answer: Y-axis

When referring to a two and three-dimensional plane, a y-axis or vertical axis refers to the vertical height of a two or three-dimensional object. In the illustration, the y-axis plane moves up and down and INTERSECTS with the x-axis and z-axis.

An example of what uses the y-axis is a computer mouse. Moving the mouse up or down increases and decreases the y-axis value, allowing the computer to know where the mouse cursor is on the screen.

JavaScript y-axis mouse position

Below is a JavaScript that shows you the mouse's x-axis and y-axis position as you move your mouse pointer in the screen area.

Note

If you're on a smartphone or tablet, tap your finger to get position of the tap.

VAR mie = (navigator.appName == "Microsoft Internet Explorer") ? true : false; if (!mie) { document.captureEvents(Event.MOUSEMOVE); document.captureEvents(Event.MOUSEDOWN); } document.onmousemove = function (e) {mousePos(e);}; document.onmousedown = function (e) {mouseClicked();}; var mouseClick; var keyClicked; var mouseX = 0; var mouseY = 0; function mousePos (e) { if (!mie) { mouseX = e.pageX; mouseY = e.pageY; } else { mouseX = event.clientX + document.body.scrollLeft; mouseY = event.clientY + document.body.scrollTop; } document.show.mouseXField.value = mouseX; document.show.mouseYField.value = mouseY; return true; }

Mouse x-axis position.
Mouse y-axis position.

Other EXAMPLES of a y-axis

Below are a few other examples of how the y-axis is used on a computer.

• Help position and KEEP track of the mouse cursor on the screen.
• A character or another object in a computer game that moves up and down on the screen has a y-axis value that determines its location.
• With a chart, the y-axis is the data expressed vertically. The higher a data point is represented vertically, generally, the greater the value of the data which corresponds with that point on the x-axis.
• In computer graphics, if you want to draw a vertical line, use the y-axis to determine the start and end point of the line. DRAWING a two-dimensional object requires only the x-axis and y-axis. However, a 3D object requires a z-axis.
• Other input devices like a joystick also use a y-axis to control objects such as a tank or airplane.
