SCIENTIFIC GRAPH API

• Generates data graphs and best fits plots by calling API endpoints with data files and parameters
• Plots and fits are available as downloadable pdfs (best format for LaTeX)
• Web version hosted on Vercel, URL: https://andrewsonlinenotes.vercel.app/utilities/1

General Guidelines

• Acceptable data formats: csv, npy, npz, HDF5, JSON
• First row of csv should be the headers (x labels, y labels etc)
• Size Option: Single Column Plot (3.375 inches _ 3 inches), Double Column Plot (7 inches _ 3 inches)
• Try to not have duplicate headers, Pandas automatically appends numbers to duplicate colummns, so if that is not what you want, try to have unique column headers

Plot API

Scatter Plot

• Endpoint: /plot/scatter
• Format: x : y
• Example Data:
  

Errorbar Plot

• Endpoints:
  • /plot/errorbar1x → x : y : error x
  • /plot/errorbar1y → x : y : error y
  • /plot/errorbar2xy → x : y : error x : error y

Bar Graph

• Endpoint: /plot/bar
• Format:
  • Column 1: Data
  • Column 2: Labels

Pie Chart

• Endpoint: /plot/pie
• Format:
  • Column 1: Category
  • Column 2: Percentage

Boxplot

• Endpoint: /plot/boxplot
• Format:
  • Column 1: Category
  • Column 2: Value

Single Histogram

• Endpoints:
  • /plot/eqhistogram
  • /plot/varyhistogram
• Formats:
  • Single file → Data → Counts/Frequencies
  • Two files → Data, Weights → Counts/Frequencies : Bins
• Other Parameters:
  • bins:
    • Integer (e.g., bins=10): Automatically bins data into evenly spaced intervals.
    • List (e.g., bins=[1, 2, 5]): Uses exact numbers for bin spacings.

Heatmap and Contour Map (CSV Format)

• Endpoints:
  • /plot/imshowhmap
  • /plot/pmeshhmap
  • /plot/pmeshfunchmap
  • /plot/imshowhmap
  • /plot/contour
• Data Format:
  • Matrices must have a single header value "m" to distinguish them from ordinary data.
  • Example Data:
    
• Normalization:
  • "minmax" or "zscore"
• Missing Values Handling:
  • "mean", "median", or 0
• Colormap Selection:
  • Choose from: Matplotlib Colormaps
  • Heat Function:
  • Write your custom heat function.
  • Only accepts x, y as variables and functions from numpy, scipy and python builtin
• Contour Levels:
  • Integer (e.g., levels=10): Automatically generates evenly spaced contour levels.
  • List (e.g., levels=[-1, 0, 1]): Uses exact numbers as contour levels.
