  1. LESSON-3

  2. Excel Charts A chart is a graphic which provides visual representations of the workbook data, and is not located in a specific cell or range • Data Series– is a set of values that you want to chart. • 255 data series can be plotted in a single chart. • Data point– Each value in a data series is called a data point i.e. the value in a cell. • A data series can contain upto 32,000 data points/values for 2 dimensional chart and 4,000 for three dimensional chart. • Category– is the label or heading under which the values are stored.

  3. Data Series & Categories Category Data Series Data point

  4. Chart Elements Chart Title Plot Area Chart Area Tick mark Data marker Y axis Title Legend Y axis Tick Mark X- axis X axis Title X axis Labels

  5. Chart Elements • Chart Area –the area where all the chart elements reside. • Plot Area – within the chart area where the chart is plotted i.e. the rectangular area bounded by the X and Y-axis. • Data Marker – is a graphic representation of value of data point in a chart. • Axis – is the line that contains a measurement by which you compare plotted value. • X-axis – contains data markers denoting category values. • Y-axis – contains the value of data being plotted.

  6. Chart Elements • X-axis Title –which briefly describe the X-axis categories. • Y-axis Title –identifies the values being plotted on the Y-axis. • Chart Title – which labels or describe the entire chart. • Tick Marks – are small lines similar to marks on a ruler, that are uniformly spaced along each axis and identify the position of category names or values. • Grid Lines – are the extensions of tick marks that helps identify the value of the data markers. • Legend – A chart legend indicates which data marker represents each series when you chart multiple series.

  7. Types of Excel Charts

  8. Chart Placement, Planning Chart can be placed in two ways • Embedded chart – Placing a chart near data in same worksheet. • Adv: Can see and print data and chart on the same page. • Chart sheet – Placing a chart on a separate sheet. • Adv:Much larger and No data on chart page. • Chart planning guidelines • What is the purpose of the chart i.e. comparison trend and etc? • What data to be represented by the chart? • Which chart type is the best to represent the data? • Where should the chart be placed - along with the data or on a separate sheet ? • What feature should the selected chart type contain - i.e. markers, legends etc? • Sketch the chart and decide finally.

  9. Creating a chart • A chart can be created using Chart Wizard (from Insert menu). • The Chart Wizard is a four-step, on-screen guide that helps you prepare a chart from an Excel worksheet. • Choose the chart type • Choose the data to chart and how it appears • Add chart options • Determine chart placement

  11. Editing a Chart Changing data values in the worksheet automatically updates the chart Change value here… …see data marker change here

  12. Formatting a Chart Formatting Option • Formatting a Chart’s • Plot Area • Data Series • Chart Area

  13. Annotating a chart Annotation text Arrow • A text annotation is a label that you add to a chart to further describe data Improving a chart • You can improve a chart by including / deleting or updating a data series . • Insert or delete a column or row and update with data. • Drag the data range and include or remove in the chart.

  14. Working with 3-D Pie Charts

  15. Working with 3-D Pie Charts Working with 3-D Pie Charts -Select Chart from “Menu Bar” – chart option - then chose “3D view” • Click the Chart Wizard button • In the first step of the chart wizard, select the pie chart type and sub-type 3D with visual effect. • In the second step select chart's data range and series in ( row / column) • In the third step, make any modifications to the chart's appearance • In the fourth and final step, specify the location for the chart, then click the OK button
