CS代写|数据可视化代写Data visualization代考|Too Many Attributes

In Section 3-1, we discuss the importance of using preattentive attributes in data visualizations to make them easy to understand by the audience. However, using too many preattentive attributes in the same visualization can cause confusion for the audience. Consider again the case of Stanley Consulting Group. The company wants to examine how consultant characteristics such as job title, length of time with the company, and highest educational degree attained are related to the amount of billable hours filed by that consultant. Figure $3.36$ attempts to show this information.

All of the information the company wants to consider is shown in Figure 3.36: the number of billable hours for each consultant (on the vertical axis), the length of time at the company (on the horizontal axis), the consultant’s job title (indicated by the color of the marker in the chart), and the highest degree attained by the consultant (indicated by the shape of the marker in the chart). Figure $3.36$ uses several preattentive attributes from Section 3-1 including spatial positioning, shape, and color. However, because we are using many different preattentive attributes, this chart is difficult for an audience to process. It requires the audience to scan back and forth between the markers in the chart, the legends, and the vertical and horizontal axes. Therefore, this is probably not a particularly useful chart.

A better chart than what is shown in Figure $3.36$ would concentrate on examining fewer relationships and using fewer preattentive attributes. The exact choice of which features to show on the chart depends on the goals of the chart and needs of the audience. If it is more important to examine the relationship between billable hours, length of time at the company, and the job title of the consultant, then a chart such as the one shown in Figure $3.37$ is preferred.

CS代写|数据可视化代写Data visualization代考|Color Psychology and Color Symbolism

Color psychology is the study of the innate relationships between color and human behavior. Although human psychological reaction to various colors is not uniform, research suggests that people react with a high degree of consistency to various colors. For example, blue skies are thought to make us happier and more energized, while gray skies are thought to make us sadder and more lethargic.

The psychological categorization of colors as warm and cool is thought to be of particular importance. Cool hues are considered to be soothing, calming, and reassuring. On the other hand, warm hues evoke energy, passion, and danger. Purple, blue, and green hues are generally considered to be cool, and yellow, orange, and red hues are generally considered to be warm.
Color symbolism refers to the cultural meanings and significance associated with color. Although they are similar and it is sometimes difficult to discern between them, color psychology and color symbolism are distinct types of stimuli. Color psychology deals with instinctive relationships between color and human behavior, and color symbolism refers to learned relationships between color and human behavior. This implies that color symbolism can differ much more across cultures and can change over time. For example, blue symbolizes masculinity in Europe and North America, but it symbolizes femininity in China. People associate green with envy in the United States, but yellow symbolizes envy to the French and Germans. Yellow is associated with success and power in many African cultures, and it symbolizes refinement to the Japanese. The relationships between color and human behavior that are due to color psychology are much more pervasive and reliable than the relationships between color and human behavior that are due to color symbolism, and we must be careful when using color symbolism in selecting the color palette for a chart.
Although color psychology and color symbolism are distinct, their ramifications are similar. When selecting colors for a visual display, it is important to recognize that color can enhance or change audience perception, so you should carefully consider the consistence of the traits associated with the various colors you are considering with your message. Figure $4.5$ provides a summary of various traits that have been associated with different colors. ${ }^1$

在第 3-1 节中,我们讨论了在数据可视化中使用 preattentive 属性以使其易于被观众理解的重要性。但是,在同一个可视化中使用过多的 preattentive 属性可能会导致观众混淆。再次考虑斯坦利咨询集团的案例。公司想要检查顾问特征(例如职位、在公司工作的时间长度和获得的最高教育程度)与该顾问提交的计费小时数之间的关系。数字3.36试图显示此信息。

公司想要考虑的所有信息如图 3.36 所示:每位顾问的计费小时数(纵轴)、在公司的时间长度(横轴)、顾问的职位(标由图表中标记的颜色)和顾问达到的最高程度(由图表中标记的形状表示)。数字3.36使用第 3-1 节中的几个 preattentive 属性,包括空间定位、形状和颜色。但是,由于我们使用了许多不同的预注意属性,因此该图表很难让观众处理。它要求观众在图表中的标记、图例以及垂直和水平轴之间来回扫描。因此,这可能不是一个特别有用的图表。

比图中显示的更好的图表3.36将专注于检查更少的关系并使用更少的前注意属性。在图表上显示哪些功能的确切选择取决于图表的目标和观众的需求。如果更重要的是检查计费时间、公司工作时间和顾问职位之间的关系,那么如图所示的图表3.37是首选。

色彩心理学是对色彩与人类行为之间内在关系的研究。尽管人类对各种颜色的心理反应并不统一,但研究表明,人们对各种颜色的反应高度一致。例如,蓝天被认为让我们更快乐、更有活力,而灰色的天空被认为让我们更悲伤、更昏昏欲睡。

暖色和冷色的心理分类被认为是特别重要的。冷色调被认为是舒缓、平静和令人安心的。另一方面,暖色调唤起能量、激情和危险。紫色、蓝色和绿色色调通常被认为是冷色调,黄色、橙色和红色色调通常被认为是暖色调。
颜色象征是指与颜色相关的文化意义和意义。尽管它们相似并且有时很难区分它们,但色彩心理学和色彩象征主义是不同类型的刺激。颜色心理学处理颜色与人类行为之间的本能关系,而颜色象征主义是指颜色与人类行为之间的学习关系。这意味着颜色象征在不同文化中的差异会更大,并且会随着时间而改变。例如,蓝色在欧洲和北美象征着阳刚之气,而在中国则象征着阴柔之气。在美国,人们将绿色与嫉妒联系在一起,而黄色在法国和德国人则象征着嫉妒。黄色在许多非洲文化中与成功和权力联系在一起,它象征着日本人的精致。
尽管色彩心理学和色彩象征主义是不同的,但它们的后果是相似的。在为视觉展示选择颜色时,重要的是要认识到颜色可以增强或改变观众的感知,因此您应该仔细考虑与您正在考虑与您的信息相关的各种颜色相关的特征的一致性。数字4.5提供与不同颜色相关的各种特征的摘要。1
