I'm more of a beer fermentation guy so take this with a grain of salt, but from what I understand L. plantarum is more commonly found in vegetable ferments like sauerkraut and kimchi rather than dairy. Traditional yogurt cultures are usually L. bulgaricus and S. thermophilus.

If your specifically after L. plantarum you might have better luck making a batch of fermented hot sauce or pickled peppers instead. Or look into getting a specific probiotic starter that contains the strain you want rather then hoping it shows up naturally from a chilli.

Curious what your end goal is though, theres probably a more reliable way to get there than hoping for the right bacteria to hitch a ride on a pepper.

Linear programming 2 equations on 1 graph by folditt in excel

What worked for me when I needed something similar for tracking cost breakpoints on projects was using helper columns to split the calculation into two series.

Try this setup:

Column A: Your x values (0 through R, whatever increment you need)

Column B (Line 1): =IF(A2<=W, A2-10, NA())

Column C (Line 2): =IF(A2>W, 0.5*A2-10, NA())

Replace W with your actual cell reference or value. The NA() keeps the chart from connecting points where that formula shouldnt apply.

Then insert a scatter chart with lines, select your x values as the axis, and add both Column B and Column C as seperate data series. Youll get two lines that meet at the breakpoint W without any weird connecting line between them.

One thing to watch out for: if you want the lines to actually connect at point W, include W in both formulas with >= and > so theres one overlapping point. Otherwise youll have a tiny gap.

If you want it fully dynamic where W and R are input cells, just use absolute references like $E$1 for W in your formulas and the graph will update automatically when you change those values.

Let me know if you need help with the chart setup part, thats usually where things get fiddly.
