Open your data file(s), using Open Data buttons on the Home menu category of Menu Bar.
2. Load the temperature variable and show it on a Scalar Cross-section.
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
click the Add Scalar Cross-section button on Layer menu category, select options, and then click "OK", or
right-click the temperature variable on the Variables Pane, and select 'Add Scalar Cross-section'.
Rendering Pane will immediately display the distribution, and a new layer will be added to the Layers Pane.
3. Change the visualization style - contour vs. raster (optional).
On Horizontal Plane menu category of Menu Bar, you can select one of the following visualization styles:
Contour : show distribution with discrete iso-level contour lines (optionally with filled colors)
Raster : show distribution with smoothly filled colors
Dot : show distribution with colored dots for grid points
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.
4. Change the settings for color mapping (optional).
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. Control the size and location of the plane (optional).
You can control the size and location of the plane by using Rendering Pane only. To do this, you need to :
switch from Globe mode to Map mode,
double-click one of the corners of the plane, to reveal the control handles,
drag the control handles to change the size and location of the plane.
You can also change latitude/longitude of the plane, by dragging control handles in the Area Pane.
