Hello! I created a scatter plot with maximum temperatures and daily data from the 1930s to 2020. I want to create a straight line in the 100F (for high temperature reference) in my y axis but I can't. I tried many codes from Matworks but no success.
Hope anyone can help me with this.
This is the plot I get and the code I used
figure('Name','Daily TMAX');
hold on
scatter(Date,DailyTMAX,'b','*')

Date = datetime([1930:2020], 1, 1);
DailyTMAX = randn(size(Date));
figure('Name','Daily TMAX');
hold on
scatter(Date,DailyTMAX,'b','*')
yline(max(DailyTMAX), 'r--')

Just a comment that hold on is not necessary when using xline or yline. However, adding it has no adverse effect.
Also, it is best practice to always pair a hold on with a corresponding hold off.
