## 统计代写|数据可视化作业代写data visualization代考|Geographic Maps

A geographic map is generally defined as a chart that shows characteristics and the arrangement of the geography of our physical reality. A geographic map of the United States shows state borders and how the states are arranged. A choropleth map is a geographic map that uses shades of a color, unique colors, or symbols to indicate quantitative or catrgorical variahles hy gengraphic reginn of area

Let us consider ercating a choropleth map of the United States for which color shading is used to denote the population of each state. A darker shade will indicate a higher population and a lighter shade will indicate a lower population.

The population data for the fifty states can be found in the file StatePopulation. A portion of the data set is shown in Figure 2.18. The fifty states in the United States are listed in column $\mathrm{A}$ and the corresponding estimated population of each state is in column B.

The following steps will create a choropleth map using shading to denote size of the population for each state.
Step 1. Select cells A1:B51
Step 2. Click the Insert tab on the Ribbon
Step 3. In the Charts group, click the Maps button Maps
Select Filled Map
After editing the chart title as outlined in Section 2-2, we obtain the map in Figure 2.19. The map shows the states with the highest populations are California, Texas, Florida, and New York.
As an example of a choropleth map with categorical data, let us consider how Amazon is able to deliver packages so quickly to its U.S. customers. Amazon distributes customer orders from fulfillment centers which stock most of the products Amazon sells. The file AmazonFulfill contains categorical data by state. For each state, “Yes” or “No” is provided to denote whether or not that state has at least one Amazon fulfillment center. A portion of the Amazon fulfillment data set is shown in Figure 2.20.

A heat map is a two-dimensional (2D) graphical representation of data that uses different shades of color to indicate magnitude. Let us consider the data in file SameStoreSales. The data are shown in Figure $2.22$. The rows of this data set correspond to store locations and

the columns are the months of the year. The percentages given indicate the change in sales over the same month last year for a given store. This percentage change metric is commonly used in the retail industry and is referred to as “same-store-sales.” For example, the St. Louis store’s sales for January are $2 \%$ lower than last year in January.
Figure $2.23$ shows a heat map of the same-store-sales data given in Figure $2.22$. The cells shaded red in Figure $2.23$ indicate declining same-store sales for the month, and cells shaded blue indicate increasing same-store sales for the month. The following steps create the heat map shown in Figure $2.23$.
Step 1. Select cells B2:M17
Step 2. Click the Home tab on the Ribbon.
Step 3. Click Conditional Formatting in the Styles group
Select Color Scales and click Blue-White-Red Color ScaleThe heat map in Figure $2.23$ helps the reader to easily identify trends and patterns. We can see that Austin has had positive increases throughout the year, while Pittsburgh has had consistently negative same-store sales results. Same-store sales at Cincinnati started the year negative but then became increasingly positive after May. In addition, we can differentiate between strong positive increases in Austin and less substantial positive increases in Chicago by means of color shadings. A sales manager could use the heat map in Figure $2.23$ to identify stores that may require countermeasures and other stores that may provide ideas for best practices. Heat maps can be used effectively to convey data over different areas, across time, or both, as seen here.

## 统计代写|数据可视化作业代写data visualization代考|Treemaps

A treemap is a chart that uses the size, color, and arrangement of rectangles to display the magnitudes of a quantitative variable for different categories, each of which are further decomposed into subcategories. The size of each rectangle represents the magnitude of the quantitative variable within a category/subcategory. The color of the rectangle represents the category and all subcategories of a category are arranged together.

Categorical data that is further decomposed into subcategories is called hierarchical data. Hierarchical data can be represented with a tree-like structure, where the branches of the tree lead to categories and subcategories. As an example, let us consider the top ten brand values given in the file BrandValues (source: Forbes.com). The data appear in the file as shown in Figure 2.24. Each observation consists of an industry, a brand within an industry, and the value of the brand.

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
