In last week’s post, I introduced a graphics challenge that I use when I teach a MATLAB graphics class to new technical support engineers at MathWorks. This week, I show the first part of the solution. This video shows how we draw one curve with two colors and how we draw a horizontal line across the plot.
This week’s video makes use of concepts I’ve introduced in previous videos:
Very nice tutorial, I was wondering how you were running the function without calling it from another script or workspace until you explained the Edit Run Configuration part, that’s something I never used before, keep up the good work Doug.
Glad the advanced users are learning something from these videos also. The File Exchange file looks good. You even did the interpolation near the line. I cover that in my language class, it is kind of fiddly, and not really the point of this exercise, so I only assign that to the people that get done early! :)
Thanks Doug. NaN does the trick indeed in your code. Whether we are needing to represent a dual color graph with other colors than the MATLAB defaults, I suggest this modified version:
function createDualColorPlot(x, y, lev)
[yHigh, yLow] = FilterY(y,lev);
cox = [0.58 0.39 0.39];
coz = [0.23 0.44 0.34];
xlimits = xlim;
The emphasis in the lines can be useful to give prominence some pieces of the graph.
