    Tables-FAQ When I type numbers into my table, it changes them. It either rounds decimals that I don’t want rounded, or completely changes the number! You need to format your cells. Highlight the cells that are causing problems and right click. Go down to “Format Cells.” Click on the “Number” tab along the top and choose what format you want your cells to be in. Most of the time you’ll want to choose the “number” option and then click how many decimal places you need. For the Car project, we want our data cells (Age, actual price, linear data, and exponential data ) to all be “Number” (2 nd  option down) and rounded to 2 decimal places. How do I enter an exponent for an equation? Type in your entire equation. Highlight the part that should be an exponent, go to the top left side of the screen and click on the little box at the corner of “font” and select superscript. For the Car project, our exponential equations have exponents in them. Type in the full equation  –  example: y = 14441.302(0.998)x. The x is supposed to be an exponent… Highlight the x, go to the top left side of the screen and click on the little box at the corner of “font” and select superscript.   Creating graphs and charts 1.) Enter all your information into a table For the Car Project we are making 1 table, but with 3 “y” columns –  One for the prices from the internet, one for the Linear Data, and one for the Exponential Data. Your “x” values is the ag e of the car (ex. 1995 car is 17 years old for X). 2.) Go to the menu bar across the top of the screen and move to Insert. In the middle of the new menu bar, you’ll see about 7 options for chart categories. Choose your chart and then the subcategory. For the Car project we want a “Scatter” chart (second option from the ri ght). When you click on “Scatter” five more sub -categories show up. You want the chart in the top right (scattered points connected by smooth lines). When the chart pops up in your screen, you’ll want to click and drag it over to the side so you can sti ll see your entire data table. 3.) To insert your data into the graph, right click in the graph and click on “Select Data.” A box will now show up that you can use to enter your data into the chart.  4.) In the “chart data range” category you will have your x-values. Put your cursor in the box, clear out anything already written there, and then moved to your table and highlight your x-values. For the Car proj ect, you’ll highlight your Age of car , in increasing order 5.) To input each set of data  –   In the box on the left, you’ll click on “Series 1” and then the “Edit” box above it. - Type in a name for your series (this will be what comes up in the legend). - Move the box for “Series X - values,” erase anything already in that box, and then highlight your x-values (in order, top to bottom). - Move to the box for “Series Y - Values,” erase anything already in that box, and highlight your y-values from your table (again, in order!). - Click OK For the Car projec t, we’ll start with the Actual Price . -   The Series name is “Raw Data”  -   The x-values is the Age of Car -   The y-values are the Actual Prices 6.) If you only have one set of data, move to #7. If you need to add more data sets to your graph, click “Add” above the box on the left. Follow the same steps above (in #5) for each set of data that you have. For the Car project, you need to add “Linear Data, and “Exponential Data.” 7.) After you’ve added all data  sets, click OK. To make your graph easier to read, you should make it a separate sheet. To do this, right click in the blank white space on the right, and click on “Move Chart.” Select the button for “New Sheet.” Now you can move back and forth between the chart and your data table by clicking on “Chart 1” and “Sheet 1” in the lower left hand corner of the screen. CONGRATULATIONS!!! YOU’VE SUCCESSFULLY CREATED A CHART!!! However, this chart is hard to read and understand, so now you need to format it. Formatting Graphs/Charts   Adding a Title to your Graph In the menu bar across the top of the screen, click on “Layout,” the 2 nd  option from the right. In the middle of the new menu bar you’ll see a box for “Labels.” Click on “Chart Title.” Choose how you want your title to appear (as an overlay over the graph, or up above the graph). “Chart Title” will now show up on your graph and you can click on it to edit and type in your title. Adding axis titles Same as above... Click on “Axis Titles” & choose Horizontal or Vertical Axis.   Changing the background on the graph Right click in the m iddle of your graph on a blank spot (don’t click on top of a line or point) and select “Format Plot Area.” Choose what “Fill” you want.      Changing axis labels   Right click on any label in the axis you want to change and select “Format Axis.” Under Axis Options you can change the start value (minimum) by clicking the button next to fixed and typing in a new value (same process to change maximum). To change the distance between labels you need to change your “major axis unit.”  For the Car project we want our x-axis to run from 0-20 (to give a little buffer room on either side of the graph), and your major axis unit should be 1 so that there is a tick mark every year. Your y-axis labels/units will depend on the prices that you are working with. Changing the look of a line/data series   Right click on any point in the data series (on that line), and select “Format Data Series.” By scrolling through the options on the left side, you can change the color and size of the line, and the color, size, or type of marker being used. **NOTE - If you are printing on a black and white printer, please make sure we can tell the difference between the lines on your graph. An option you have is to give each line a different thickness. C hanging the type of line for one data series Right click on any point in the data series (on that line), and select “Change Series Chart Type.” You can now go through and change what type of graph is being used for just that set of data. (To change ALL sets of data, right click on any blank s pace in the graph and select “Change Chart Type.”  For the Car project, we want the ACTUAL PRICE to be just plotted points (without the line) even though everything else will have the connecting line. Right click on the ACTUAL PRICE line and select “change series chart type.” You want the option that is just points (without lines) in the XY Scatter category.
