Twin Axes Demo
Twin Axes Demo
Source: twin_axes_demo.f90
Demonstrates twinx and twiny for multiple axes on one figure.
The demo plots three synthetic time series and assigns each to a different axis:
- Left y-axis: primary signal (temperature-like)
- Right y-axis: secondary signal with log scaling
- Top x-axis: cumulative index with log scaling
Run the example via:
make example ARGS="twin_axes_demo"
Outputs are written to output/example/fortran/twin_axes_demo/ in PNG and ASCII
formats.
