Plotting and animating - enhanced plotting
and animations with ncBrowse
Set Up the Plot
- In main ncBrowse window, click "New Map..." button (located under
the list of variables)
- This opens the Variable Map Window
- Set up the plot (x- and y-axis and variable(s) by dragging the items
from the left side (source) to the right side (target).
- For vectors, drag and drop u and v components
- For stick plots, assign the velocity components to the U & V cmponents.
The default is for "arrows", but you can edit the Vector Properties
to produce "sticks".
- For contours, drag and drop the parameter to be contoured
- Enter your name for the variable map you've created into the text box
at the top of the window and click Done.

Setup is complete, now make the plot and/or animate:
- Your variable will appear at the end of the list in the main ncBrowse
window. Scroll down to find it, and double click it the variable name to
plot and also open the Parameter Editor Window. You can interact
with the plot using the Parameter Editor Window.
- Edit plot parameters in the Parameter Editor Window.
Click on the "..." to the right of an axis to bring up a slider
for adjusting the axis range, or simply type the range values into the
"Start" and "End" text boxes. Click "Apply"
to implement your changes in the plot.
- Make the plot
- Animate the plot by clicking on the "movie strip"
icon to the left of the axis range in the Parameter Editor Window.
This opens the Animation Controller. Set the animation speed and use
the buttons to play, start, stop, single step and rewind. Animations
will be fast if the data file is local, and slow if the data file is

Tips on the Variable Map Window
- Red text indicates that the axis is still unspecified or a dimension that's
not matched to a variable.
- Green text means that the dimension is matched and all's well
- Clicking the "Show all dimension" text box will display the number
of points for each index in the file. The text type (italic, bold, plain)
tells you about the entity:
- italic text - this is a netCDF dimension with no variable associated
- bold text - this is a "dimension variable", and should have
- plain text- this is a variable
