z-axis (plural z-axes) (algebraic geometry) The axis on a graph of at least three dimensions that is usually drawn vertically and usually shows the range of values of a variable dependent on two other variables or the third independent variable.
What does the Z axis represent?
A three-dimensional structure. The x-axis and y-axis represent the first two dimensions; the z-axis, the third dimension. In a graphic image, the x and y denote width and height; the z denotes depth.
What is az axis called?
For 3D diagrams, the names “abscissa” and “ordinate” are rarely used for x and y, respectively. When they are, the z-coordinate is sometimes called the applicate. The words abscissa, ordinate and applicate are sometimes used to refer to coordinate axes rather than the coordinate values.
What direction is the Z axis?
The Z axis is perpendicular to the ground plane; think of it as a line drawn between the device and the center of the Earth. The value of the Z coordinate is positive upward (away from the center of the Earth) and negative downward (toward the center of the Earth).
What is XYZ position?
When performing precision shaft alignment on horizontal rotating machinery, the Z axis refers to the rotational axis or rotational centerlines. The Y axis refers to vertical position (perpendicular to the base) and the X axis refers to the horizontal position (parallel to the base).
Why do we use Z axis?
The z-axis is perpendicular to both the x-axis and y-axis and is used to plot the value of z, the third unknown in mathematics. See also Cartesian coordinates, x-axis, y-axis, and z. One of three axes in a three-dimensional Cartesian coordinate system.
How does Z-axis work?
When referring to a three-dimensional plane, a z-axis refers to the depth of a three-dimensional object. In the illustration, the z-axis plane goes front to back, and intersects with the y-axis and x-axis at the origin.
What is vertical and horizontal axis?
the line of figures or coordinates that are arranged from left to right along the bottom of a graph or map: The vertical axis represents value; the horizontal axis represents time.5 days ago.
What is Z direction?
Noun. z-direction. (algebraic geometry) The direction aligned with the z-axis of a coordinate system.
How do you read XYZ coordinates?
Cartesian coordinates of the plane The first number x is called the x-coordinate (or x-component), as it is the signed distance from the origin in the direction along the x-axis. The x-coordinate specifies the distance to the right (if x is positive) or to the left (if x is negative) of the y-axis.
Is Z axis up and down?
These axes are normally taken so that X axis is the longitudinal axis pointing ahead, Z axis is the vertical axis pointing downwards, and the Y axis is the lateral one, pointing in such a way that the frame is right-handed.
What does Z coordinate mean?
A z coordinate is the third-dimensional coordinate in a volume pixel , or voxel . Together with X and Y coordinates , the z coordinate defines a location in a three-dimensional space. See voxel for more information.
What is the YZ plane?
y-z Plane. The plane formed by the y-axis and the z-axis. See also. x-y plane, x-z plane.
What is XYZ rotation?
The XYZ system rotates about the z axis by γ. The X axis is now at angle γ with respect to the x axis. The XYZ system rotates again, but this time about the x axis by β. The Z axis is now at angle β with respect to the z axis. The XYZ system rotates a third time, about the z axis again, by angle α.
What is height in XYZ?
An X-Y-Z matrix is a three-dimensional structure whereby the x-axis and y-axis denote the first two dimensions and the z-axis is the third dimension. In a graphic image, the x denotes width, y denotes height and the z represents depth.
What is Z axis in CNC machine?
Place your hand in front of your CNC machine, aligned with the machine’s spindle, and you’ll see the axes line up perfectly. Middle finger is the Z-axis. Index finger is the Y-axis. Thumb is the X-axis.
What direction is positive z?
In both coordinate systems, the positive x-axis points to the right, and the positive y-axis points up. You can remember which direction the positive z-axis points by pointing the fingers of either your left or right hand in the positive x-direction and curling them into the positive y-direction.
What is horizontal graph?
Horizontal bar graphs represent the data horizontally. It is a graph whose bars are drawn horizontally. The data categories are shown on the vertical axis and the data values are shown on the horizontal axis.
Is a horizontal axis?
The x-axis is the horizontal plane of a graph in a Cartesian coordinate system, which gives a numerical value to each point along the horizontal x-axis, as well as the vertical y-axis (in a two-dimensional graph). An x-axis refers to the horizontal plane in a Cartesian coordinate system.
What is vertical and horizontal?
The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, “v,” which points down.
How do you remember the XYZ axis?
The x-axis is horizontal, and the y-axis is vertical. One way to remember which axis is which is ‘x is a cross so the.
What are the XY and Z coordinates?
Usually, the x-coordinate is measured along the eastwest axis, the y-coordinate is measured along the northsouth axis, and the z-coordinate measures height or elevation.
