** Does the Y-axis have to start from 0 **

However, "always start the y-axis at zero" is not a hard-and-fast rule. For example, Edward Tufte points out that in a time series, the baseline is not necessarily zero: In general, in a time-series, use a baseline that shows the data not the zero point. If the zero point reasonably occurs in plotting the data, fine.

** Does the Y-axis have to start at 0 in a bar graph **

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.

** Should a graph always start at zero **

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.”

** Why should the Y-axis start from 0 in a bar chart **

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.

** Is the y-axis always first **

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!

** What happens if y is 0 **

So if we say x is zero. Well Y is equal to zero there's no X here so Y is just equal to zero. If we said X was one y still equal to zero. So it's just zero.

** What is the rule for y 0 **

For the equation y=0, x has infinite values, whereas y must always be equal to zero. The points (3,0), (0,0), and (-3, 0) are all located on the graph of y=0 because each point gives a y value of zero.

** Does Y 0 mean the y-axis **

Any point on the x-axis is represented as (x, 0) and any point on the y-axis is represented as (x, 0). So according to the question, y = 0 means for all the values of x, y coordinate is 0. This implies, the line y=0 represents the x-axis.

** Do scatter plots always start the Y axis at 0 like a bar plot **

Because they are floating dots, a scatter plot x and y axis need not start at zero either. To go back to the start then: should you always start your bar chart at zero Yes. However, that doesn't mean that a bar chart starting at zero is always a good chart.

** What is a misleading graph that does not start at 0 **

A truncated graph (also known as a torn graph) has a y axis that does not start at 0. These graphs can create the impression of important change where there is relatively little change. While truncated graphs can be used to overdraw differences or to save space, their use is often discouraged.

** Why do you set the Y intercept to 0 when graphing **

If the curve is forced through zero, the intercept is set to 0 before the regression is calculated, thereby setting the bias to favor the low end of the calibration range by “pivoting” the function around the origin to find the best fit and resulting in one less degree of freedom. Ref: SW-846, Method 8000C, Section …

** Where on the y-axis do we start the graph **

The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0). In graphs with only positive values for x and y, the origin is in the lower left corner.

** 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) .

** What always goes on the y-axis **

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).

** Why should the y-intercept be 0 **

The y intercept of a graph is the point where the graph intersects the y-axis. We know that the x-coordinate of any point on the y-axis is 0. So the x-coordinate of a y-intercept is 0.

** 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) .

** What happens if the Y in the slope is 0 **

A line with zero slope is perfectly flat in the horizontal direction. No matter what value of x you have, you get the same y-value. It does not increase or decrease.

** Does the line of best fit have to start at 0 in scatter graph **

Lines of best fit do not have to begin at (0,0).

** What is always on the y-axis of a bar graph **

Sometimes bar graphs are made so that the bars are sideways like in the graph to the left. Then the y-axis is horizontal (flat). Typically, the y-axis has numbers for the amount of stuff being measured. The y-axis usually starts counting at 0 and can be divided into as many equal parts as you want to.

** How do you know if a graph is misleading **

INVESTIGATION: Misleading graphsOmitting the baseline.Showing an inappropriate or irregular scale.Scale or labels not clearly given.Leaving data out.Using pictures or three-dimensional graphics that distort differences.Using the wrong graph for a given data type.

** What are 5 ways a graph can be misleading **

There are numerous ways in which a misleading graph may be constructed.Excessive usage. The use of graphs where they are not needed can lead to unnecessary confusion/interpretation.Biased labeling.Pie chart.Improper scaling.Truncated graph.Axis changes.No scale.Improper intervals or units.

** Should I set intercept to 0 **

The regression line is forced to pass through the origin (0, 0). Therefore, unless your regressors are standardized or mean-centered, it's not a good idea to set the intercept to 0 when fitting the model. Even when your regressors are standardized or mean-centered, you should still include the intercept.

** Why does the Y axis of some line graph not start with zero **

Data in a line chart is encoded by position (x, y coordinates), whereas in a bar chart data is represented by length. This subtle difference changes the way a reader uses the chart, meaning that in a line chart it's ok to start the axis at a value other than zero, despite many claims that they are always misleading.

** Do you go up 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 it 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).
