Interactive 2D Plotting & Slicing Guide
The NetCDF Plot View (NetCDFPlotView) renders high-performance 2D scientific visualizations with customizable color palettes, multi-dimensional slicing, and interactive pan/zoom.
Launching the Plot View
- In the NetCDF Multi-Page Editor or Project Explorer, double-click a variable or right-click and choose Visualize Variable.
- In the popup dialog, select the two display dimensions (e.g.
X for the horizontal axis and Y for the vertical axis).
- Click OK. The
NetCDFPlotView opens in the workbench.
Customizing Visual Parameters
- Color Palette Selection: Choose from standard scientific colormaps including
Spectral, Jet, Plasma, Viridis, Turbo, Coolwarm, and more.
- Color Depth: Configure interpolation depth (e.g.
256 or 1024 discrete colors) for smooth gradients.
- Axis Direction: Invert horizontal (X) or vertical (Y) coordinate directions via toolbar toggle buttons to correct north-down or west-right grids.
- Zoom & Pan: Use mouse drag and zoom controls to focus on regions of interest.
Slicing Extra Dimensions
For 3D or 4D variables (e.g. [time, height, y, x]):
- In the view toolbar, select the extra dimension you wish to step through (e.g.
time).
- Click the Previous Index (
<) or Next Index (>) buttons to advance the active slice.
- The plot updates immediately to reflect the new slice.
