NTA Level 5 • Semester 2 • PST05209 Creation of Chart from Health Data Using Health Information Management • Source Session/Topic 4 Full source-text version: all educational wording from the extracted learning source is retained; only presenter/tutor metadata and web-layout noise are removed, while formatting is improved for readability. Session 4: Creation of Chart from Health Data Using Spreadsheet Learning Tasks By the end of this session students are expected to be able to: • Define a chart as applied in Ms Excel • Explain types of Ms Excel charts • Create a chart using Ms Excel principles • Format data using condition formatting CHART AS APPLIED IN MICROSOFT EXCEL • A chart is a visual representative of data in both columns and rows. • Charts are usually used to analyse trends and patterns in data sets. • For example, the district hospital pharmacist have been recorded the malaria drugs inventory figures in Excel for the past three years; using charts, the pharmacist can easily tell which year had the most consumption of Malaria drugs and which year had the least. • Charts are used to compare set targets against actual achievements. • Use the following data for chart practice.

Charts allow your audience to see the meaning behind the numbers. The Types of Microsoft Excel Charts Types of charts • Different scenarios require different types of charts. • Excel provides a number of chart types • The type of chart depends on the type of data that used during chart design. • To help simplify things for the users, Excel has an option that analyses data and makes a recommendation of the chart type used. List Excel Chart Types i. Pie ii. Column iii. Line iv. Bar v. Combo vi. Scatter HMIS NOTES B.Boy Explanation with Diagrams The following table shows some of the most commonly used charts S/N CHART WHEN SHOULD EXAMPLE TYPE USE IT? 1 Pie Chart When user want to quantify items and show them as percentages. 2 Bar Chart When user want to compare values across a few categories. The values run horizontally HMIS NOTES B.Boy 3 Colum When user want chart to compare values across a few categories. The values run vertically 4 Line chart When user want to visualize trends over a period of time i.e. months, days, years, etc. 5 Combo When user want Chart to highlight different types of information HMIS NOTES B.Boy The Scatter Chart The purpose of a Scatter Chart is to observe how the values of two series compares over time or other category. HMIS NOTES B.Boy PARTS OF EXCEL CHART i. Chart area ii. Data marker iii. Data series iv. Axis v. Tick mark vi. Plot area vii. Gridlines viii. Chart text ix. Legend HMIS NOTES B.Boy Explanation of Each part of the Graph Chart area: Everything inside the chart window, including all parts of the chart (labels, axes, data markers, tick marks, and other elements listed here). Data marker: A symbol on the chart that represents a single value in the worksheet. A data marker (or data point) may be a bar in a bar chart, a pie in a pie chart, or a line on a line chart. Data markers with the same shape or pattern represent a single data series in the chart. Data series: A group of related values, such as all the values in a single row in the chart. A chart can have just one data series (shown in a single bar or line), but it usually has several. Axis: A line that serves as a major reference for plotting data in a chart. In two- dimensional charts there are two axes — the x-axis (horizontal/category) and the y-axis (vertical/value). Tick mark: A small line intersecting an axis. A tick mark indicates a category, scale, or chart data series. A tick mark can have a label attached. Plot area: The area where Excel plots your data, including the axes and all markers that represent data points. Gridlines: Optional lines extending from the tick marks across the plot area, thus making it easier to view the data values represented by the tick marks. Chart text: A label or title that you add to the chart. Attached text is a title or label linked to an axis such as the Chart Title, Vertical Axis Title, and Horizontal Axis Title that you can’t move independently of the chart. Legend: A key that identifies patterns, colors, or symbols associated with the markers of a chart data series. The legend shows the data series name corresponding to each data marker (such as the name of the blue columns in a column chart). HMIS NOTES B.Boy The Procedures of Creating a Chart Using Microsoft Excel Procedures for creating charts in Excel • Open Excel • Enter the data from the sample data table above (Table 4) • The workbook should now look as follows • To get the desired chart the user should follow the following steps HMIS NOTES B.Boy • Select the data you want to represent in graph • Click on INSERT tab from the ribbon • Click on the Column chart drop down button • Select the chart type you want • The user can able to see the following chart HMIS NOTES B.Boy • When you select the chart, the ribbon activates the following tabs: • Try to apply the different chart styles, and other options presented in your chart. HMIS NOTES B.Boy The Procedures of Using Conditional Format in Microsoft Excel Conditional Formatting • Conditional formatting refers to formatting that is only applied when the specified condition is true.
