1. ME 142 Engineering Computation I Graphing with Excel Chapter 3

2. Creating a Basic XY Scatter Graph  Excel supports many types of Graphs

3. Creating a Basic XY Scatter Graph  XY Scatter is most common in engineering Do not confuse with Line Graph  To simplify graph creation process: Organize data into columns Omit any blank rows Pre-select data to be graphed

4. Creating a Basic XY Scatter Graph XY Scatter Graph x-axisy-axis -545 -427 -313 -23 -3 0-5 1-3 23 313 427 545

5. Linking Chart Titles to a Cell  Axis and chart titles can also be linked to cells Select the title in the graph Click on the formula bar and type in “=“ Select the cell to link to

6. Adding Data to an Existing Graph  Easiest way to add data is to select existing graph and drag highlighted range to new area  Works to add both columns and rows  Graph is automatically updated

7. Plotting Multiple Curves  Selecting data prior to chart creation is easiest  May also drag range to add additional curves

8. Adding a Trend Line  To add a trendline, right-click on the curve and select Add Trendline…

9. Modifying a Graph  Some common tasks include Resizing /moving the graph Moving/Deleting the legend Changing axis scales Adding/Updating titles
