What graphing technique can you use to show correlation

[Guest]

I have a data set that shows Days of the week by (y axis) hours of the day (x
axis)(0,1,2,3,4 etc..). The data is the number of hours on. How can, or what
kind of graph can I use to show correlation, or no correlation.
Thank u

Your question is about a 0.1 Sigma understanding level. Please rephase

I normally use a scatter chart of some type to show correlation
or plot the mean and standard deviation of one variable against another
variable if there is too much data for a simple scatter chart.
