Your tutorials are awesome, and they have been very useful during my internship at a corporation which does not provide its employees with MATLAB, which is what I am used to using. See screenshot: 2. Use a scatter plot (XY chart) to show scientific XY data. Instead, I believe that it is important to educate people on WHY one procedure GENERALLY should not be utilized, rather than assuming that because you cannot fathom a case in which broken axes are appropriate, such a case does not exist.

One variable controls the position on the x-axis of a point, while the other variable controls the position on the y-axis. For example, I may look at varying the flow of a chemical in a reactor over many orders of magnitude to see the impact on some property of a crystal. Suggestions? Is it appropriate to “zoom in” on the range that my data is in, rather than showing the whole axis from 0 to 7000?
