![]() Figure 4.1 Stock Trendsīefore we create the line chart, it is important to identify why it is an appropriate chart type given the message we wish to communicate and the data we have. We can use this chart in a presentation to show whether stock prices have been increasing, decreasing, or remaining constant over the designated period of time. ![]() This chart will be used to communicate a simple message: to show how the index has performed over a two-year period. This chart will show the trend of the NASDAQ stock index. Figure 4.1 shows part of the data that will be used to create two line charts. ![]() The first chart we will demonstrate is a line chart. Usually the vertical axis – where the numbers are found. Usually the horizontal axis – where the labels are found Identify the values for the X and Y axes.Īfter you have selected a chart type, you may find that drawing a sketch is helpful in identifying which values should be on the X and Y axes. The type of chart you select will depend on the message you are communicating and the data you are using. In some cases, you may need to create formulas or consolidate items into broader categories. Once you have a clear message, identify the data on a worksheet that you will need to construct a chart. If there is no main point or important message that can be revealed by a chart, you might want to question the necessity of creating a chart. Identify the main idea you are trying to communicate to an audience. Table 4.1 Key Steps before Constructing an Excel Chart Step To determine what data should be used when creating a chart, you must first identify the message or idea that you want to communicate to an audience. When creating a chart, it is common for only specific data points to be used. Just because you have data in a worksheet does not mean it must all be placed onto a chart. Table 4.1 “Key Steps Before Constructing an Excel Chart” provides a brief summary of these points.Ĭarefully Select Data When Creating a Chart If you can visualize what your chart is supposed to look like, you will have an easier time selecting information correctly and using Excel to construct an effective chart that accurately communicates your message. One of the ways to identify which values belong on the X and Y axes is to sketch the chart on paper first. The third key point is identifying the values that should appear on the X and Y axes.The chart type you select will depend on the data you have and the message you intend to communicate. The second key point is selecting the right chart type.Throughout this chapter, we will reinforce the intended message first before creating each chart. This is critical in helping you select specific data from a worksheet that will be used in a chart. Therefore, you must first decide what message or idea you wish to present. It is important to keep in mind that the primary purpose of a chart is to present quantitative information to an audience. The first is identifying your idea or message.Choosing a Chart Typeīefore we begin, let’s review a few key points you need to consider before creating any chart in Excel. This is necessary not only to demonstrate the construction of charts but also to explain how to choose the right type of chart given your data and the idea you intend to communicate. To demonstrate the variety of chart types available in Excel, it is necessary to use a variety of data sets. This section reviews the most commonly used Excel chart types. Construct a stacked column chart to show how a percent of total changes over time.Learn how to use a pie chart to show the percent of total for a data set.Construct a column chart that compares two frequency distributions.Create a separate chart sheet for a chart embedded in a worksheet.Learn how to use a column chart to show a frequency distribution.Construct a line chart to present a comparison of two trends.Construct a line chart to show a time series trend.Var chrt = document.getElementById("chartId"). Let’s take an example in which we will use Cartesian axes for creating a chart − The syntax of using cartesian axes is given below − These axes are called cartesian axes.Ĭartesian axis uses " " namespace. ![]() A cartesian chart uses 1 or more X-axis and 1 or more Y-axis to map the data points on to two-dimensional (2-D) canvas. Basically, axes are used to determine how our data maps to a pixel value on the chart. For any chart or graph, axes are an integral part.
