Matlab Map Projection Plot: How to Plot Supernovae Coordinates on a Hammer Plot

Click For Summary
SUMMARY

This discussion focuses on plotting Supernovae coordinates using a Hammer plot in MATLAB. The user seeks guidance on creating a 2D representation of a sphere's surface, specifically a Hammer projection. A suggestion is made to utilize MATLAB's polar plot function to achieve a similar effect, although the original concept of a Hammer plot is not well-documented. The conversation highlights the need for creative solutions when specific plotting techniques are not readily available.

PREREQUISITES
  • Basic knowledge of MATLAB programming
  • Understanding of polar coordinates and plotting
  • Familiarity with spherical coordinate systems
  • Concept of map projections, specifically the Hammer projection
NEXT STEPS
  • Research how to implement MATLAB's polar plot function for custom projections
  • Explore existing MATLAB toolboxes for advanced plotting techniques
  • Study the mathematical principles behind the Hammer projection
  • Learn about other spherical plotting methods in MATLAB, such as the 'surf' function
USEFUL FOR

Mathematics enthusiasts, astrophysicists, and MATLAB users interested in advanced plotting techniques and visualizing astronomical data.

Hi there,

I am trying to plot the coordinates of Supernovae onto what I think is known as a hammer plot i.e a 2D plot representing the surface of a sphere. I have no idea how to do this, and have been searching the internet to no avail. Can anyone offer any advice ? I only have a basic knowledge of Matlab.

Thank you.

Unfortunately, I've never heard of a hammer plot, and a search for it (even in quotes, which looks for exactly that phrase) turns up nothing of relevance (though it does turn up your post, and a link to the Hebrew Hammer, which I thought was a hilarious movie).

Perhaps you can make something work with MATLAB's polar plot function? You'd probably have to figure out how to plot lines for appropriate lobes (like a one-piece orange skin) but you can probably work something out:
