# How to interpret axis of Histogram and distribution curve?

After doing statistical analysis of data I got the below figures:

The data contains a line length in meters which is represented with Line(m). The purpose here is to confirm the distribution behavior of line lengths(m). Now, based on above two figures:

1. What kind of information x-axis and y-axis of both figures convey? Particularly for the distribution curve (pdf)?. From the first figure, it is somehow clear that it shows the percentage of the data fall within that region.
2. The x-axis of second figure shows the values from [0 - 80]. Does this means line length (m)?

2. Every distribution has a spread or else mathematical computations won't be feasible for any kind of inference/analysis. For Line data, in both your plots, X-axis takes that responsibility. Unit (m specified by you) associated to values shall entirely depend on nature of your Line data feature.
