An axis is the reference line that is used to measure coordinates on graphs and grids. There are typically two axis lines (axes) on a graph; the y-axis and the x-axis. The y-axis is vertical, while the x-axis is horizontal. When these two lines are together on a graph they are referred to as the axes of the graph.

How do you find the axis of a graph?
The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a . Example 1: Find the axis of symmetry of the parabola shown.
What is the axis of a graph used for?
A reference line drawn on a graph (you can measure from it to find values).
What is an axis line?
The definition of an axis is a real or imaginary line on which something rotates, or a straight line around which things are evenly arranged. An example of axis is an imaginary line running through the earth on which the earth rotates.
Is the y-axis the series?
By default, the text that appears in the legend is taken from the chart’s data range. Series are sets of related data.The Y axis is vertical on most charts (except for bar charts, where the Y axis is horizontal).
What is the horizontal axis of a chart known as?
The horizontal (category) axis, also known as the x axis, of a chart displays text labels instead of numeric intervals and provides fewer scaling options than are available for a vertical (value) axis, also known as the y axis, of the chart.
What is the axis of an object?
An axis is an invisible line around which an object rotates, or spins. The points where an axis intersects with an object’s surface are the object’s North and South Poles.Each planet in our solar system rotates on its axis.
What does axes mean in math?
An axis is a line with respect to which a curve or figure is drawn, measured, rotated, etc. The most common axes encountered are commonly the mutually perpendicular Cartesian axes in the plane or in space. The plural of “axis” is “axes,” pronounced “ax-ees.”
What is a value axis?
Usually refers to the vertical axis in 2D charts and graphs, which shows the values being measured or compared. Refer to it as the value (y) axis on the first mention.In 3D charts, the z-axis is usually the value axis.
Can a graph have two y-axis?
A dual y-axis chart allows you to summarize or plot two y-axis variables that have different domains. For example, you can plot the number of cases on one axis and the mean salary on another.The following steps use the basic elements so that you can generalize the steps for other varieties of dual axis charts.
Can a graph have 2 y-axis?
When the data values in a chart vary widely from data series to data series, or when you have mixed types of data (for example, currency and percentages), you can plot one or more data series on a secondary vertical (Y) axis. The scale of the secondary Y-axis reflects the values for the associated data series.
Why is the vertical axis called the value axis?
The Y axis is vertical on most charts (except for bar charts, where the Y axis is horizontal). Because it displays values, the Y axis is also called the value axis.
What is y-axis also known as?
Also called axis of ordinates. (in a plane Cartesian coordinate system) the axis, usually vertical, along which the ordinate is measured and from which the abscissa is measured.
How do you explain axis to a child?
An axis is an imaginary line an object turns around. This imaginary line runs directly through the object’s center, from the north to the south poles. Although we can’t feel the Earth spinning, it makes one complete turn, each day, around its own axis.
What are axis and orbit?
Axis is an imaginary line about which a body rotates. Orbit is the regularly repeated elliptical course of a celestial object or spacecraft about a star or planet.
What is an axis Class 6?
Axis: The imaginary line around which the earth rotates is called its axis. Orbit: The imaginary line on which the earth moves around the sun is called its orbit.
What is the axis of a shape?
The axis of symmetry is an imaginary straight line that divides a shape into two identical parts, thereby creating one part as the mirror image of the other part. When folded along the axis of the symmetry, the two parts get superimposed.This line can be vertical, horizontal, or slanting.
What is the difference between axes and axis?
Axis is the axis of the plot, the thing that gets ticks and tick labels. The axes is the area your plot appears in.
What is category axis and value axis?
Axes come in two types: category and value. Category axes show the names of the chart’s categories. Labels showing the category names appear between ticks. Value axes show numbers against which the data points are plotted.
What is plot area Class 7?
Legend: A box that helps in identifying various plotted data series by assigning a unique colour or pattern to a particular data series in a chart. Plot area: The area containing the chart, axes and gridlines of a chart.
Which chart is used to plot the data for a single data series?
Pie Chart
A Pie Chart displays one series of data. A data series is a row or column of numbers used for charting.
