In the label view, items are indicated by their label and, by default, also by a circle. For each item, the font size of the item’s label and the

size of the item’s circle depend on the weight of the item.3 If items have been assigned to clusters, each item’s circle is displayed in the color of the cluster to which the item belongs. Alternatively, if colors have been specified for each item individually (using the red, green, and blue columns in a map file; see Subsection 3.1), each item’s circle is displayed in the color of the item. By default, to avoid overlapping labels, only a subset of all labels is visible. Also, by default, no lines between items are displayed. However, this can be changed on the Options tab in the action panel. The label view is particularly useful for a detailed examination of a map. 

    在标签模式（label view）图中，每个节点的标签和其对应的圆环是缺省状态。对于每个节点，其标签的大小和圆环的大小与其权重相关。如果节点被划分为不同的聚类，其圆环呈现不同颜色。系统提供三种配色方案：红、绿、蓝；白、蓝、紫色；白、灰黑。

   In the density view, items are indicated by their label in a similar way as in the label view. Each point in a map has a color that depends on the density of items at that point. By default, this color is somewhere in between red and blue. The larger the number of items in the neighborhood of a point and the higher the weights of the items, the closer the color of the point is to red. Conversely, the smaller the number of items in the neighborhood of a point and the lower the weights of the items, the closer the color of the point is to blue. The density view is particularly useful to get a quick overview of the

important areas of a map. 

   在密度模式（density view）图中，每个节点标识与标签模式下相同。图中的每个节点根据其密度有一种颜色。图中缺省颜色是红和蓝。一个节点越大，表示其权重越大，其颜色越接近于红色。相反，如果其权重越小，则其颜色越接近于蓝色。这种模式对于快速获得一幅图中的重要内容的概貌非常有用。

• Cluster Density View. The cluster density view is available only if items have been assigned to clusters. The cluster density view is similar to the ordinary density view except that the density of items is displayed separately for each cluster of items. In the cluster density view, the color of a point in a map is close to the color of a certain cluster if there are a large number of items belonging to that cluster in the neighborhood of the point. Like in the ordinary density view, items with high weights count more heavily than items with low weights. The cluster density view is particularly useful to get a quick overview, for each cluster separately, of the important areas of a map. 

   在密度聚类（Cluster Density View）图中，只有节点被分成了不同聚类族才有效。这在这种模式下，每个节点的颜色和其特定的聚类族一致。这种模式对于快速发现每个聚类族非常有用。

• Scatter View. In the scatter view, items are indicated by a small circle. If items have been assigned to clusters, each item’s circle is displayed in the color of the cluster to which the item belongs. Alternatively, if colors have been specified for each item individually (using the red, green, and blue columns in a map file; each item’s circle is displayed in the color of the item. No labels are displayed in the scatter view. By default, lines between items are not displayed either, but this can be changed on the Options tab in the action panel. The scatter view can be useful to get an overview of the general structure of a map. The way in which a map is shown in the scatter view is similar to the way in which a map is shown in the overview panel discussed below.

    散点模式（Scatter View）图中，每个节点都表现为一个小的圆环。如果节点被聚为不同的类，每个圆环用同样的颜色来表示。
