##### 2. Load the temperature variable and show it on a layer.
Open your data file(s), using buttons on the _Home_ menu category of _Menu Bar_.
##### 3. Change the settings for color mapping (if necessary).
##### 2. Load the wind vector data and show it on a layer.
##### 4. Change the visualization settings - contour vs. raster (if necessary).
In order to visualize the distribution of the variable on a layer, you can either
##### 5. Explore temperature distributions at different altitudes (if any).
* click the _Add Vector Plane_ menu button on _Layer_ menu category, select variable/area/level etc, and then click "OK", or
* right-click one of u/v components of wind on the _Variables Pane_, select _'Add Vector Plane'_.
_Rendering Pane_ will immediately display the vector field of wind, and a new layer will be added to the _Layers Pane_. By default, wind flow will be shown using arrows at each grid points.
##### 3. Explore wind flow at different altitudes (if any).
On _Horizontal Plane_ menu category of _Menu Bar_, you will find _Vertical Level_ drop-down control, where you can select height level among all the levels available in your dataset. You can also click _Move Up / Move Down_ button in order to increase / decrease the selected level.
##### 4. Change the settings for color mapping (if necessary).
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.
##### 5. Change the visualization style - wind vector vs. wind barbs vs. streamlines (if necessary).
On _Vector Plane_ menu category of _Menu Bar_, you can select one of the following visualization styles:
* Wind vector : show distribution using arrows with variable length & color
* Wind barbs : show distribution using wind barbs
* Streamlines : show distribution using streamlines (optionally with animation)
Each menu button has drop-down submenu, where you can set various options for each visualization style.
