##### 1. Open data file.
|
|
##### 1. 开启数据档案
|
|
|
|
|
|
|
|
Open your data file(s), using _Open Data_ buttons on the _Home_ menu category of _Menu Bar_.
|
|
使用菜单栏中主页目录选单的开启数据按键开启您的数据档案。
|
|
|
|
|
|
|
|
##### 2. Load the temperature variable and show it on a Scalar Cross-section.
|
|
##### 2. 读取温度变量并在一个纯量剖面上显示
|
|
|
|
|
|
|
|
In order to visualize the distribution of the variable on a vertical cross-section, your dataset should include multiple datasets of the same variable at different altitudes. If you indeed have multiple datasets, you can either
|
|
如要将一个垂直截面的变量分布可视化，您必须拥有包含同一个变量但位于不同 高度的多份数据数据。如果您确认拥有这些数据数据，就可以进行以下任一动作:
|
|
|
|
|
|
|
|
* click the _Add Scalar Cross-section_ button on _Layer_ menu category, select options, and then click "OK", or
|
|
* 点击位在图层目录选单中的新增向量水平面按键，选择选项，然后点击「确认」;或
|
|
|
* right-click the temperature variable on the _Variables Pane_, and select _'Add Scalar Cross-section'_.
|
|
* 以鼠标右键点击变量面板上的温度变量，然后选择「新增纯量剖面」。
|
|
|
|
|
|
|
|
_Rendering Pane_ will immediately display the distribution, and a new layer will be added to the _Layers Pane_.
|
|
渲染面板会立即显示分布，并在图层面板添加一个新的图层。
|
|
|
|
|
|
|
|
##### 3. Change the visualization style - contour vs. raster (optional).
|
|
##### 3. 改变可视化类型─等值线或光栅(选用)
|
|
|
|
|
|
|
|
On _Horizontal Plane_ menu category of _Menu Bar_, you can select one of the following visualization styles:
|
|
您可以在菜单栏的水平面面版目录选单中选择以下可视化类型:
|
|
|
|
|
|
|
|
* Contour : show distribution with discrete iso-level contour lines (optionally with filled colors)
|
|
* 等值线 : 以离散等级等值线显示分布(可选择是否填色)。
|
|
|
* Raster : show distribution with smoothly filled colors
|
|
* 光栅 : 以平顺填满的颜色显示分布。
|
|
|
* Dot : show distribution with colored dots for grid points
|
|
* 点阵 : 在网点格中以色点显示分布。
|
|
|
|
|
|
|
|
Each menu button has drop-down submenu, where you can set various options for each visualization style. For example, you can display character labels (including "H"/"L" for geopotential height) at the peak locations of the distribution.
|
|
每一个目录按键都有下拉式子目录，您可以在此针对每一个可视化类型设定多个 选项。例如，您可以在此分布顶点显示字符卷标(包含代表地理高度的「H」/ 「L」)。
|
|
|
|
|
|
|
|
##### 4. Change the settings for color mapping (optional).
|
|
##### 4. 改变色彩映射的设定(选用)
|
|
|
|
|
|
|
|
Double click the vertical _Color Bar_ on the right-hand side of _Rendering Pane_. A popup dialog named _'Setup Colormap and Limit Range'_ will show up, where you can change various options regarding the color mapping.
|
|
您可以双击位在渲染面板右侧垂直的色条，在名为「设置色阶与极限范围」的弹出式对话框中改变多种与色彩映像相关的选项。
|
|
|
|
|
|
|
|
##### 5. Control the size and location of the plane (optional).
|
|
##### 5. 控制平面的大小和位置(选用)
|
|
|
|
|
|
|
|
You can control the size and location of the plane by using _Rendering Pane_ only. To do this, you need to :
|
|
使用渲染面板控制平面的大小和位置。如要执行，请您:
|
|
|
1. switch from _Globe_ mode to _Map_ mode,
|
|
1. 从全球模式切换为地图模式，
|
|
|
2. double-click one of the corners of the plane, to reveal the control handles,
|
|
2. 双击平面的其中一个角落，跳出控制杆，
|
|
|
3. drag the control handles to change the size and location of the plane.
|
|
3. 拖曳控制杆以改变大小或高度。
|
|
|
|
|
|
|
|
You can also change latitude/longitude of the plane, by dragging control handles in the _Area Pane_.
|
|
您也可以利用拖曳区域面板的控制杆改变平面的经度/纬度。
