 +        * be sure that each line is identified (titled) by its category (lowscore, avgscore, median, hiscore, yourscore), especially as identified in the graph key
 +        * your line should is the same, only having a greater thickness (at least 4); this should help it stand out nicely against the rest of your graph.
 +          * and, plot your line last, that will cause it to draw over any lines it will intersect with
 +
 +
 +====End result====
 +What you are aiming for is a graph that strongly resembles this one:
 +
 +{{  https://lab46.g7n.org/~wedge/content/images/spring2018.unix.attr.png  |Project Metrics graph}}
 +
 +... only it adds an additional line: YOUR actual scores on the projects.
 +
 +So this graph will be a nice visual indicator of how you did in various aspects related to the class as a whole.
 +
 +=====Spirit of project=====
 +The spirit of the project embodies many aspects we've been focusing on throughout the semester:
 +
 +  * recognizing patterns to employ effective solutions in problem solving
 +  * utilizing concepts and tools covered
 +  * demonstrating comprehension of concepts, tools, and problems
 +  * employing concepts in knowledgeable and thoughtful manner
 +  * following instructions
 +  * implementing to specifications
 +  * utilizing creativity
 +  * being able to control solution via consistent, clear, and organized presentation
 +
 +Basically: I want your solution to be the result of an honest, genuine brainstorming process where you have (on your own) figured out a path to solving the problem, you have dabbled and experimented and figured things out, and you can command the concepts and tools with a fluency enabling you to pull off such a feat. Your solution should demonstrate the real learning that took place and experience gained.
 +
 +Cutting corners, avoiding work, skimping on functionality, cheating through getting others to do work for you or finding pre-packaged "answers" on the internet violates the spirit of the project, for they betray your ability to pull off the task on your own.
 +

 +</code>
 +
 +Additionally:
 +  * Solutions not abiding by spirit of project will be subject to a 25% overall deduction
 +  * Solutions not utilizing descriptive why and how comments will be subject to a 25% overall deduction
 +    * comments should be consistent in appearance (adopt a style; one that promotes readability)
 +  * Solutions not utilizing indentation to promote scope and clarity will be subject to a 25% overall deduction
 +    * indentation should be no fewer than 3 spaces (or 3-space tabs); I prefer 4.
