Algorithm (Workflow)
This function, named color, is designed to generate a color index from a given color character. It is part of the SG-Library and was created by Tim Lueth in 2012.
Input Parameters
- c: A character representing a color. The accepted characters are 'r', 'y', 'm', 'c', 'g', 'b', 'w', and 'k'.
Output Results
- cm: An index corresponding to the colormap VLcol.
Algorithm Steps
- Define a string
cmap containing the characters 'k', 'b', 'g', 'c', 'r', 'm', 'y'.
- Check if the input
c is numeric. If it is, set cm to c and return.
- Use a
switch statement to determine the index cm based on the input character c:
- Case 'w': Set
cm to 7.
- Case 'y': Set
cm to 6.
- Case 'm': Set
cm to 5.
- Case 'r': Set
cm to 4.
- Case 'c': Set
cm to 3.
- Case 'g': Set
cm to 2.
- Case 'b': Set
cm to 1.
- Case 'k': Set
cm to 0.
- Otherwise: Set
cm to 7.
- If there are no output arguments (
nargout==0), perform the following visualization steps:
- Call
SGfigure with parameters -30 and 30.
- Create a bar object
A using SGbar.
- Apply the color index
cm to the bar object using SGcolorfaces.
- Plot the object with transparency using
SGplotalpha.
