Errorbar Demo

Errorbar Demo

Source: errorbar_demo.f90

Demonstrates error bar plotting with both symmetric and asymmetric errors for scientific data visualization.

  • errorbar_demo.f90 - Source code with comprehensive error bar examples

  • errorbar_plot.png/pdf/txt - Example outputs

  • Symmetric error bars: Single error value for both directions

  • Asymmetric error bars: Different upper and lower error bounds
  • X and Y errors: Error bars on both axes
  • Visual customization: Cap size, line width, colors, markers
  • Multiple datasets: Comparing experimental data with different uncertainties
  • Scientific styling: Professional presentation for publications

! Basic symmetric errors call fig%errorbar(x, y, yerr=yerr, label='Data with errors')

! Asymmetric errors call fig%errorbar(x, y, yerr_lower=y_lower, yerr_upper=y_upper)

! Custom styling call fig%errorbar(x, y, yerr=yerr, capsize=8.0_wp, & elinewidth=2.0_wp, marker='o', color=[1.0, 0.0, 0.0])

The demo generates examples showing: - Basic error bars with measurement uncertainty - Multiple datasets with different error magnitudes - Custom styling and professional scientific presentation

Perfect for scientific plotting where uncertainty visualization is essential.
