## 统计代写|数据可视化代写Data visualization代考|Custom Color Using the Hsl Color System

In the previous examples, we used Excel’s color palettes to demonstrate the various types of color schemes. However, it is also possible to customize the colors used in a chart. We can directly control the hue, saturation, and luminance (HSL) in Excel through the Colors dialog box, which allows for control of each of these three color characteristics in the following ways.
Hue: The color’s hue expressed as an integer in the range 0 to 255 . The primary and secondary colors of the RGB primary color mode using fixed values for saturation and luminance are:

As the value of the Hue parameter increases, the indicator $-1_{1}^{1}$ – moves horizontally from left to right across the color spectrum control in the Colors dialog box to indicate the selected hue.
Sat: The color’s saturation expressed as an integer in the range 0 to 255 ; higher Sat: values correspond with more intense or pure color, and lower Sat: values produce increasingly gray shades. Setting Sat: to 0 results in a gray tone regardless of the hue and luminance settings. In Figure 4.16, we illustrate changing saturation with fixed levels of hue and luminance in the Colors dialog box.

As the value of the Sat parameter increases, the indicator $-\pi$ – moves vertically from the bottom to the top of the color spectrum control in the Colors dialog box to indicate the selected saturation, which alters the grayness/increases the parity of the color

Lum: The color’s luminosity expressed as an integer in the range 0 to 255 . Setting Lum: to 255 results in white and setting Lum: to 0 results in black. In Figure 4 .17, we illustrate changing luminance with fixed levels of hue and saturation in the Colors dialog box.

As the value of the Lum: parameter increases, the indicator $-1$ moves vertically from the oottom to the top of the Luminosity slide control in the Colors dialog box to indicate the ielected luminance, which reduces and increases the lightness of the color.

As an example, let us consider again the zoo attendance stacked column chart shown n Figure 4.18. Suppose we wish to use a different shade of orange to represent the adult attendance. The following steps illustrate how we can change the adults category to a cusomized color.
Step 1. Open the file ZooChart
Step 2. Click on the orange portion of any column and then right click
Step 3. Click the Shape Fill button $\frac{\text { B. }}{\text { sut }}$
Select More Fill Colors…
When the Colors dialog box appears, click the Custom tab
Step 4. Next to Color model: choose HSL from the drop-down menu
Step 5. Set Hue to 21 , Sat to 238 , and Lum to 182
Step 6. Click OK
The zoo data with the lighter shade of orange is shown in Figure 4.18.
In some instances, you may want to replicate a color used in an existing image. You can use the Eyedropper, a tool in PowerPoint that determines the HSL settings for colors used n an image. For example, consider an analyst who is creating a presentation to give to the management of Grappenhall Publishers and wants to use the color scheme of the compaay’s logo (shown in Figure 4.19) in creating this presentation.

## 统计代写|数据可视化代写Data visualization代考|Inconsistency across Related Charts

When creating several charts for a single report, a presentation, an ongoing analysis, or a data dashboard, it is critical that color is used consistently. Using different color schemes or using different colors to represent categories on different charts will confuse the audience and dramatically increase its cognitive load.

Consider the zoo attendance data shown in Figure 4.8, shown again here in Figure 4.30. The column chart uses orange and blue, two complementary colors, to distinguish between adult and children. Now suppose as part of a presentation to the Zoo Board, you have Figure $4.30$ on a slide, and it will be followed by a second slide that shows adult versus children December ticket revenue for the last five years. Consistency in the use of color across slides will make it easier for the audience to comprehend. So, rather than use different colors, it is helpful to use the same orange and blue to represent other factors related to adults and children. Figure $4.31$ shows a chart of the December revenue data. The consistency in the use of color will help the audience’s comprehension of the data presented across the series of slides.

Color works differently in print and projection. Projected presentations will be seen from a distance, and the audience will generally have relatively little time to review specific aspects of a projected presentation. Use of thick lines, color contrast, and relatively high saturation and luminance in this medium is critical. Use sharp outlines and saturated contrasting colors when creating a presentation that is to be projected. On the other hand, the audience will generally be close to printed presentations and will have more time to review specific aspects of a printed report, so you do not need to rely as extensively on thick lines, color contrast, and relatively high saturation and luminance in this medium. Use softer outlines with colors with less saturation, lower luminance, and less contrast when creating a presentation that is to be printed.

Colors will also vary from monitor to monitor, projector to projector, and monitor to projector. When possible, go through your entire presentation in advance with the projection equipment that will you use when giving the actual presentation, and make necessary adjustments iteratively until you are satisfied with the projected colors. If this is not possible, avoid extremely bright colors in your color scheme as those often differ most between the appearance on the monitor you use when creating the presentation and the appearance on the screen with the projection system you will ultimately use.

Similarly, colors vary from printer to printer and from monitor to printer. Consider creating a test page that includes each of the colors you use in your report on the printer you will ultimately use to print your report. Print this single page, review the results, adjust as necessary, and repeat the process until you are satisfied with the printed colors.

Sat：颜色的饱和度，以 0 到 255 范围内的整数表示；较高的 Sat：值对应于更强烈或更纯的颜色，较低的 Sat：值产生越来越多的灰色阴影。无论色调和亮度设置如何，将 Sat: 设置为 0 都会产生灰色调。在图 4.16 中，我们说明了在颜色对话框中使用固定级别的色调和亮度来改变饱和度。

Lum：颜色的亮度，表示为 0 到 255 范围内的整数。将 Lum: 设置为 255 会产生白色，将 Lum: 设置为 0 会产生黑色。在图 4 .17 中，我们说明了在颜色对话框中使用固定级别的色调和饱和度来改变亮度。
