## 统计代写|数据可视化代写Data visualization代考|Excel’s Recommended Charts Tool

Excel provides guidance for chart selection through its Recommended Charts tool. The Recommended Charts button is found in the Charts group of the Insert tab on the Ribbon. The following steps demonstrate the use of the Recommended Charts tool using the zoo attendance data in the file Zoo shown in Figure 2.3.

Step 1. Select cells A1:B13 Step 2. Click the Insert tab on the Ribbon Step 3. Click the Recommended Charts button Checemmended in the Charts group
The Insert Chart dialog box appears as shown in Figure 2.39. Four different chart types are recommended, a column chart (also shown to the right), a bar chart, a funnel chart, and a combination (combo) chart. Clicking on any of the four charts on the left will display that chart enlarged and to the right, in the same way the column chart is displayed on the right in Figure $2.39$. This allows you to see an enlarged version of the chart before committing to the chart.
Step 4. Select the Clustered Column chart and click OK
Edit the chart as outlined in Section 2-2.

## 统计代写|数据可视化代写Data visualization代考|Preattentive Attributes

The act of “seeing” a chart or table used for data visualization involves a combination of our eyes and brains. Our eyes receive inputs as reflections of light from a visualization that our brains then must differentiate and process. The process through which our brains interpret the reflections of light that enter our eyes is known as visual perception.

The process of visual perception is related to how memory works in our brain. At a very high level, there are three forms of memory that affect visual perception: iconic memory,

short-term memory, and long-term memory. Iconic memory is the most quickly processed form of memory. Information stored in iconic memory is processed automatically, and the information is held there for less than a second. Short-term memory holds information for about a minute, and our minds accomplish this by chunking, or grouping, similar pieces of information together. Estimates vary somewhat, but it is believed that most people can hold about four chunks of visual information in their short-term memories. For instance, most people find it difficult to remember which color represents which category if more than four different colors/categories are used in a bar or column chart. Long-term memory is where we store information for an extended amount of time. Most long-term memories are formed through repetition and rehearsal, but they can also be formed through clever use of storytelling.
For most data visualizations, iconic and short-term memory are most important for visual processing. In particular, an understanding of what aspects of a visualization can be processed in iconic memory can be helpful for designing effective visualizations. Preattentive attributes are those features that can be processed by iconic memory. We can use a simple example to illustrate the power of preattentive attributes in data visualization. Examine Figure $3.3$ and count the number of $7 \mathrm{~s}$ in the figure as quickly as you can.

## 统计代写|数据可视化代写Data visualization代考|Length and Width

When we refer to the preattentive attributes of length and width for data visualization, we are generally referring to their use with lines, bars, or columns. Therefore, length refers to the horizontal, vertical, or diagonal distance of a line or bar/column while width refers to the thickness of the line or bar/column (see Figure 3.7). Length is useful for illustrating quantitative values because a longer line corresponds to a larger value. Length is used extensively in bar and column charts to visualize data. Because it is much easier to compare relative lengths than relative sizes, bar and column charts are often preferred to pie charts for visualizing data. Consider data on the number of accounts managed by eight account managers. Figure $3.11$ displays these same data as a pie chart (using size of pie pieces to indicate numher of accounts and color to indicate the manager) and a har chart (using length of bafs to indicate number of accounts and labels on the vertical axis to indi cate the manager).

It is much easier to see that the manager with the most accounts managed is Elijah and that Kate manages the second-most accounts from the bar chart in Figure $3.11 \mathrm{~b}$ than from the pie chart in Figure $3.1$ la. We could make the bar chart even easier to interpret by sorting the bars by their length with the longest bar on top and the shortest bar on the bottom by using the Excel Sort function as described in the following steps. The data appear in Figure $3.12$

“看到”用于数据可视化的图表或表格的行为涉及我们的眼睛和大脑的结合。我们的眼睛接收来自可视化的光反射的输入，然后我们的大脑必须区分和处理这些输入。我们的大脑解释进入我们眼睛的光的反射的过程被称为视觉感知。
