3 Charting Data Excel offers a variety of options for charting data. By charting the data in a spreadsheet, you can present the data in a visual format that can aid in the interpretation of the data. Excel offers 14 standard chart types with each chart type containing a variety of subtypes from which to choose. The standard chart types are as follows: Type Column Bar Line Pie XY (scatter) Area Doughnut Radar Surface Bubble Stock Cylinder Cone Pyramid Purpose Shows data changes over a period of time or shows comparisons of data Shows comparisons among individual items Shows trends in data at equal intervals Shows the proportional size of items in relation to the whole for a single data series Shows the relationship among numeric values in several data series or plots two groups of numbers in a series Shows the magnitude of change over time Similar to a pie chart but allows comparison of two or more data series Compares the aggregate values of numbers Allows you to determine optimum combinations between two sets of data Similar to an XY chart were the size of the bubble represents a third variable Typically used to chart changes in stocks including high-low-close values Similar to a Bar or Column chart but the cylinder adds dramatic effect Similar to a Bar or Column chart but the cone adds dramatic effect Similar to a Bar or Column chart but the pyramid adds dramatic effect The following is an example of a standard bar chart: Chart Title Income Statement $16, $14, Plot Area Y Axis (Value) $12, $10, $8, $6, $4, REVENUE Payroll Rent Supplies Legend $2, $- Jan Feb Mar X Axis (Category) Data Series Chart Area 3

Also, you can format the text within the Text Box the same way you format text within the Worksheet. 15

16 Using VLOOKUP VLOOKUP (Vertical Lookup) allows you to lookup information in a table based on specific data, such as a grade range. Then you can use that data to extract associated data such as a letter grade. The syntax for a VLOOKUP formula is as follows: VLOOKUP(lookup_value,table_array,col_index_num,range_lookup) Lookup_value Table_array Col_index_num Range_lookup = the value in the first column of the array = the table of information in which the data is looked up = the column number in the table_array from which the matching value must be returned = a logical value that indicates whether or not VLOOKUP should match to an exact value (FALSE) or an approximate value (TRUE or Blank). Lesson 1: VLOOKUP on the Activity: Complete following page 16

17 Lesson 1: VLOOKUP Complete the following activities for Sheet: Grades of Advanced Excel.xls. 1. In c3, use the following formula to perform a vertical lookup: =vlookup(b3,$a$14:$b$19,2) Copy this formula to c4:c11 2. In cell e3, use the following formula to perform a vertical lookup with a false argument: =vlookup(d3,$a$14:$b$19,2,false) Copy this formula to e4:e11 17

18 Auditing a Worksheet Auditing a spreadsheet will allow you to determine whether or not formulas are working the way you expect them to work. Auditing allows you to trace precedents, dependents and errors. Precedents cells that provide data to formulas. Dependents cells with formulas that pertain to cells with data. To open the Auditing Toolbar, perform the followings steps: Click on Tools from the Menu Highlight Auditing Click on Show Auditing Toolbar Trace Precedents Remove Precedent Arrows Trace Dependents Remove Dependent Arrows Clear Validation Circles Circle Invalid Data New Comment Trace Error Remove All Arrows Trace Precendents The Trace Precendents options will allow you to display the cells which relate to a particular formula.

21 Using SUMIF The SUMIF function allows you to add cells based on specified criteria. The syntax for SUMIF is as follows: =sumif(range,criteria,sum_range) Range Criteria Sum_range =The range of cells you want to evaluate =Can be a number, expression or text which defines what should be added. Ex: 15000, 15000, >=15000, classes. =The cells to add which match the criteria. Activity: Enter the following formula in cell a13: =sumif(b2:b10, >=15000,c2:c10) on the Salaries worksheet. 21

22 Using PMT The PMT function is a financial function which allows you to calculate the payments for a loan. The syntax for PMT is as follows: =pmt(rate,nper,pv,fv,type) Rate =The interest rate for the loan. Nper =The total number of payments. PV =Present value (principal) FV =Future value (if omit, assumes a 0) Type =The number 0 (end of period) or 1 (beginning of period) which indicates when payments are due.

24 Working with One-Variable Tables A One-Variable Table allows you to analyze data based on changing criteria. For instance, you can use a One-Variable Table to determine the monthly payments on a loan for various interests rates, amount of the loan or duration of the loan. In order for the One-Variable Table to work properly, you must designate an input cell either on the row or column of the table. In our example b4 (APR) will be the input cell which determines the values in the table. To create a One-Variable Table, perform the following steps: Select the table area Click on Data from the Menu Click on Table; the following will appear: Enter the cell reference for the input cell Click OK Activity: Complete Lesson 3: One-Variable Table on the following page. 24
