If the vertical variable decreases as the horizontal one increases we say there is negative correlation. This may indicate cause and effect but it may not be that simple. If the vertical variable increases as the horizontal one does (as the example above shows) then we say there is a positive correlation. One variable is plotted on the horizontal axis (usually the one that you are trying to control) and the other on the vertical axis (usually the one you expect to respond to the changes you are making). Scatter plots show the relationship between the two variables in pairs of observations. Once the data in the cells is dates with times, you can apply what I have written above.A scatter plot is a graph used to look for relationships between two variables How to use it You may want to convert your text to real date/times with the Text to Columns tool or another technique of your choice. Formatted as times, all integers will show up as midnight. Excel cannot recognize the text in column A as dates, so it just numbers the data points from first to last and plots these numbers on the X axis. Format the X axis labels to "General" and you may find that the labels are integer numbers. If you change your mind, edit your question and post a comment to let me know what you want.Įdit: Looks like your "dates" may actually be text. Not pretty, but that's what you asked for. That will cause all the date/time stamps to overlap and become unreadable, so you may want to revise that decision or make your chart very, very wide if you have more than a few hours of data or turn the X axis labels sideways which will look like this:
