A convenient module for plotting in CASSIS

Last update:12/06/14

Description

The Plot class is a simple class to plot data in CASSIS with the scripts:

import ScriptEnvironment
from Plot import Plot

Usage

• Initialize a plot:

  >>> p = Plot("Some title for the frame")
  

• Create a simple plot with x and y data:

  >>> p.plot(x, y)
  

• Add another plot:

  >>> p.add(x2, y2)
  

• Close the plot:

  >>> p.close()
  

• Clear the frame:

  >>> p.clear()
  

Options

The plot method provides options to modify the appearance of the plot.

• title: set the title
• legend: set the legend (for multiple plots the legend must be unique.)
• xlabel and ylabel: set the labels of the x and y axes
• lineWidth: set the width of the line
• lineStyle: set the style of the line. The available values are “line”, “dash” or “dot”
• lineColor: set the color of the line (example: “red”, “blue”, “pink”)
• symbol: set the symbol. The available symbols are “d”, “x”, “+”, “^”, “rectangle” and “circle”

Examples:

# A plot with blue dashed line, a title and labels for x and y
p.plot(x, y, title="Mean intensities of the spectra",
ylabel="Intensity (K)", xlabel="Index", lineColor="blue", lineStyle="dash")

# A multiplot with "+", "^" and different legends for the data
p.plot(x1, y1, symbol="+", lineColor="black", legend="CO")
p.add(x2, y2, symbol="^", lineColor="magenta", legend="CH3OH")

Limitations

• Plot doesn’t provide error bars.
• With multiple plots, a given plot cannot be removed. You have to recreate the plots
