描述----------Description----------
This GUI allows users to control the scatterplot tour by simply moving and clicking their mouses. The Variable Selection checkboxes contains all the numeric variables, and at least three of them need to be checked to make the display work. All the categorical variables go to the Class Selection box. We should select the class variable by double clicking the variable names. If users don't specify the class variable, the selected numeric variables will be considered as one class, and all points will be black. After users specify the class variable, the points will be considered as different classes according to this categorical variable, and these will appear as rainbow colors in the scatterplot tour. The Tour Type radio buttons contains four different tour types. They are the Grand Tour, Little Tour, Local Tour and Guided Tour. We can only choose one type a time. For the Guided Tour, we need to choose an index from the droplist to specify which particular search type is desired. The default index is holes. For tour type Guided(lda_pp) and Guided(pda_pp), we also need to specify class variable first. The Guided(pda_pp) is also controlled by another parameter, lambda. Lambda ranges from 0 to 1, with default at 0.02. A value of 0 will make the tour operate like Guided(lda_pp). For very high-dimensional data a value closer to 1 would be advised. The Axes Locations column contains three types. Users can specify where tour axes will be displayed. The choices are center, bottomleft and off. The Speed slider can control the speed of the 2D tour. Simply dragging the mouse along the slider, changes the speed from slow to fast. The Pause check box allow users to pause the dynamic 2D tour and have a close examination on the details. The Apply button allows users to update the 2D tour, when it doesn't automatically update. The Quit button allows users to close thie GUI window. The Help button provides information about the tour and also what this GUI can do. Tooltips will pop up when the mouse is moved over the GUI, which give hints about the functionality of the different GUI elements.
此图形用户界面允许用户通过简单的移动和点击鼠标控制散点图旅游。中的变量选择复选框包含了所有的数字变量，其中至少有三个需要进行检查，以使显示器工作。所有分类变量的类别选择框。我们应该选择的类变量，双击变量名。如果用户没有指定的类变量，选定的数值变量将被视为一类，和所有的点是黑色的。在用户指定的类变量，积分将被视为不同类别根据本分类变量，和这些都将出现作为散点图旅游的彩虹色。旅游类型“单选按钮包含四个不同的旅游类型。他们是大旅游，小旅游，本地旅游及导赏。我们只能选择一种类型的时间。导赏服务，我们需要选择从下拉列表来指定特定的搜索类型所需的索引。缺省索引孔。旅游型制导（lda_pp）和引导（pda_pp），我们还需要先指定类变量。也被控制引导型（pda_pp）由另一个参数，λ。拉姆达范围从0到1，默认情况下为0.02。如果值为0，将在旅游经营如导游（lda_pp）。对于非常高维数据的值越接近1，通常会被告知。轴位置列包含三种类型。用户可以指定将显示旅游轴。选择中心，bottomleft和关闭。速度滑块可以控制速度的2D旅游。简单的拖动鼠标沿滑块，可以改变速度由慢到快。 “暂停”复选框允许用户暂停动态二维旅游，并在细节上有着密切的检查。应用“按钮使用户能够更新的2D旅游时，它不会自动更新。退出按钮允许用户关闭世尊GUI窗口。 “帮助”按钮提供了有关旅游的信息，这个GUI可以做什么。工具提示会弹出时，鼠标移动到图形用户界面，不同的GUI元素的功能给予提示。
