Below is a sample bar graph of Precipitation (mm) vs. Time done with a spreadsheet program. In order to graph the data, you first need to enter the data into a spreadsheet. Note: you will get the actual numbers from the Weather Learning Log immediately after you complete your investigation. Here's an example of spreadsheet data.

Once you've entered the data, you need to highlight the data and have your spreadsheet program make a graph for you. This command will vary from program to program so make sure to review the instructions in your program. The spreadsheet program will then create a graph for you with the Precipitation (mm) on one side and the Time (date) on the other. Also, make sure to pick appropriate scales for both the x- and y- axes. Time will be on the x-axis for each of the graphs like this:
