Functions

• [x] evaluation of rational functions in a given point - bar plot - eval_and_show()
• [x] visualisation of sampling of the functions - bar plots - visualise()
• [x] single function grid sampling - heat map - heatmap()
  • [x] 1D, 2D

Refinement

• [x] 1 and 2D space refinement - space.show()
• [ ] 3D refinement
• [x] multidimensional - intervals of hyperectangles - visualise_by_param()

Sampling

• [x] 1 and 2D space sampling - space.show()
• [x] multidimensional - connecting values of sampled point with lines - scatter plot - visualise_sampled_by_param

Quantitative Sampling

• [x] colors with colorbar to visualise the distance
• [x] 1 and 2D space sampling - space.show()
• [x] multidimensional - connecting values of sampled point with lines - scatter plot

Metropolis-Hastings

• [x] meta plots
  • [x] trace of all points
    • [x] 2D visualisation in phase space
    • [x] with burn-in threshold
  • [x] trace of accepted points
    • [x] 2D visualisation in phase space
    • [x] with burn-in threshold
  • [x] histogram of accepted points
• [x] 1D and 2D heat map
• [x] multidimensional - connecting values of accepted point with lines - scatter plot

here i would add the visualisation for multiparametric case, as written in the e-mail on 9.2.19.
