How to Graph Functions in Excel: A Step-By-Step Guide
Step 1: Write Down the Headers
Open the program and create a new worksheet to start your graph function in Excel. First, you’ll need to write your headers into cells. These headers will determine your input and output columns. You can either name them “x” and “y”, or you can be specific and name them “sales” and “profit”, for example. Cell A1 is your input column, cell B1 is your output column.
Step 2: Insert Your Input Variables
Now, you need to enter the values for the horizontal x-axis. Start by typing the first value in cell A2, the next value in cell A3, and continue in that column until every input variable is written. Select all the values in the input column by dragging the cursor down until you have selected them all, open the “Formula” tab at the top of the page, and click “Define Name”. Write the “x” in the name box and click “OK”.
Step 3: Enter your Formula
You’ll then need to write the formula into cell B2 for your graphing function. Start by writing the “=” symbol in the B2 cell followed by the formula. Don’t leave any spaces after the “=” or else the formula won’t work.
For example, if you want to find out what levels of sales you need to break even, write “=(A2*50)-2500” in the cell. The “*” symbol represents multiplication, the number 50 is for the cost of each product and 2500 is what you paid for the products and advertising costs. You can use this calculation method to track anything.
Step 4: Put the Formula Into the Output Column
Now that your formula is written out and ready to use, copy the formula you have written in cell B2 by clicking on it and selecting the “Copy” icon at the top of the Home tab. Select all of the cells in your output column starting with cell B3, then select the arrow on the “Paste” option and click on “Formulas” to paste the formula into the cells of your current selection. You should end up with a value in each cell up to the column up to the last input and output variable.
Step 5: Create Your Graph
With all the difficult work done, you can now create your graph. Select all the cells in your worksheet containing variables, including the headers in your selection. Open the “Insert” tab, go to the “Chart” menu and select the type of graph you want to use out of the many options you have available.
You can go for a scatter plot with smooth lines, a column chart, or any other chart type that will work with your data set. You can also use a trendline to make data trends more obvious. Excel has several trendline options.
