Filled error bars to a plot
Hello,
I have been trying to create some error bars in my MATLAB script. However, I think there are some problems. I have made a figure with three plots, and I wish to have "filled" error bars for the DO and pH. Additionally, the error bars for biomass have lines between the points, which I don’t know how to remove. It would be nice if only the error bars were present.
I have inserted the code to my plot and data. Excel file is attached aswell.
growth = readtable("growthWT2.xlsx")
time = [growth.Time_h_];
timeOD = [growth.Time_h__1];
DO_1 = [growth.O21];
DO_2 = [growth.O22];
DO_3 = [growth.O23];
mean_DO = [growth.MeanO2];
S_DO = [DO_1 DO_2 DO_3];
stand_DO = std(S_DO,0,2);
pH_1 = [growth.pH1];
pH_2 = [growth.pH2];
pH_3 = [growth.pH3];
mean_pH = [growth.meanPH];
S_pH = [pH_1 pH_2 pH_3];
stand_pH = std(S_pH,0,2);
Bio_1 = [growth.biomass1];
Bio_2 = [growth.biomass2];
Bio_3 = [growth.biomass3];
mean_bio = [growth.MeanBio];
S_bio = [Bio_1 Bio_2 Bio_3];
stand_bio = std(S_bio,0,2);
