Which axis is read first
x-coordinate
The x-coordinate always comes first, followed by the y-coordinate. As you can see in the coordinate grid below, the ordered pairs (3,4) and (4,3) are two different points!
Should the y-axis always start at 0
If there's one thing almost everyone agrees on in data visualization, it's that bar charts should start at zero. Starting them anywhere else — truncating the y-axis — risks misleading your audience by making a small difference look like a big one.
What is the first y-axis
A y-axis is the vertical axis on the Cartesian coordinate plane. The y-axis starts at negative infinity and increases to positive infinity. The y-axis is also the starting, or 0 point, for measuring how far a point extends horizontally on a graph.
How are axis numbered
The first number of the coordinate is measured along the x-axis, and the second is measured along the y-axis. These positive numbers will always be plotted in the top right-hand corner, called a quadrant, of the graph or grid. Although, you will sometimes see graphs where the axes show negative numbers.
Where do you start each axis
zero
Data viz nerds agree bar charts must start at zero.
In the case of bar charts, this means that the y-axis must always start at zero. The bars in a bar chart encode the data by their length, so if we truncate the length by starting the axis at something other than zero, we distort the visual in a bad way.
What is the order of axis
In most cases where the corresponding software standards concern the inner workings of a system the axis order should stick to the mathematical notation of (x,y,z).
Do you do the y-axis first
X and y coordinates (axis) are horizontal and vertical addresses in a 2D space. The order of the x and y coordinates in the ordered pair is important. The x coordinate always comes first, followed by the y coordinate. That is why (3, 4) is not the same as (4, 3).
Should I include 0 in my vertical scale
Should all graphs start at 0 Not everyone thinks so, including the famous data visualization maven Edward Tufte, who said the advice from Huff is “wrong” and the need to show all that empty vertical space for the sake of including a zero is unnecessary.
What is Y and Z axis
The y axis is in the plane of the screen and is positive toward the top and negative toward the bottom. The z axis is perpendicular to the screen or keyboard, and is positive extending outward from the screen.
Where does the y-axis start
zero
In the case of bar charts, this means that the y-axis must always start at zero. The bars in a bar chart encode the data by their length, so if we truncate the length by starting the axis at something other than zero, we distort the visual in a bad way.
How do you know which axis to label
The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
How do you know which axis to use
The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
Is it axis 1 or axis 0
Axes are defined for arrays with more than one dimension. A 2-dimensional array has two corresponding axes: the first running vertically downwards across rows (axis 0), and the second running horizontally across columns (axis 1).
What is the rule for y-axis
Reflection in the y -axis:
A reflection of a point over the y -axis is shown. The rule for a reflection over the y -axis is (x,y)→(−x,y) .
Should line chart start at 0
Use a line chart
If your columns or bars have an inherent order (e.g. years or months), you can show them as a line chart. Like dot plots, line charts can but don't need to start at zero (you can read arguments for that in this Quartz piece).
Do graph scales have to start at 0
While it's a good idea to have best practices with displaying data in graphs, the “show the zero” is a rule that clearly can be broken. But showing or not showing the zero alone is not sufficient to declare a graph objective or conversely “deceptive.”
How do you read XYZ axis
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.
How do you read XYZ 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.
Do you read the y-axis first
X and y coordinates (axis) are horizontal and vertical addresses in a 2D space. The order of the x and y coordinates in the ordered pair is important. The x coordinate always comes first, followed by the y coordinate. That is why (3, 4) is not the same as (4, 3).
Is the Y or Z axis up
The x axis is in the plane of the screen and is positive toward the right and negative toward the left. The y axis is in the plane of the screen and is positive toward the top and negative toward the bottom. The z axis is perpendicular to the screen or keyboard, and is positive extending outward from the screen.
How do you know which axis you reflect over
We can reflect the graph of any function f about the x-axis by graphing y=-f(x) and we can reflect it about the y-axis by graphing y=f(-x). We can even reflect it about both axes by graphing y=-f(-x).
How do you read an axis
In a graph, you will find a vertical axis and a horizontal axis. The vertical axis is the line of figures or data arranged from top to bottom at the side of the graph. On the other hand, the horizontal axis is the line of figures or data arranged along the bottom of the graph.
What is axis 1 and 0
Axes are defined for arrays with more than one dimension. A 2-dimensional array has two corresponding axes: the first running vertically downwards across rows (axis 0), and the second running horizontally across columns (axis 1).
Is Axis 0 default
Axis for the function to be applied on. For Series this parameter is unused and defaults to 0. For DataFrames, specifying axis=None will apply the aggregation across both axes.
How do you know when to flip over the y-axis
The rule for a reflection over the y -axis is (x,y)→(−x,y) .
