## Why does it make sense to have a point 0 0 on your plot?

(0,0) is a data point for all density graphs because with zero mass there is zero volume.

## What does the point 0 0 mean on a graph?

It mean the origin of the coordinates. Explanation. A graph on a plane has the y-axis and the x-axis. They meet at a point labeled 0 which is the starting point of all point. This point is the point with coordinate (0, 0) and it is referred to as the origin.

## Why do line graphs start at 0?

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.

## Is the origin of a graph always 0 0?

Scatter plots use the same positional method of encoding each data point, but I have never heard anyone say that scatterplot axes should start at zero. In most cases, a zero-based axis makes sense, but it ultimately depends on the data and visualization used.

## Should Y axis always start at 0?

However, “always start the y-axis at zero” is not a hard-and-fast rule. If the zero point reasonably occurs in plotting the data, fine. But don’t spend a lot of empty vertical space trying to reach down to the zero point at the cost of hiding what is going on in the data line itself
