Module graphs

This module allows you to draw basic line graphs on the LCD screen, or on the web graph if you are running inside websensors.

# Set the style of a named graph in the output box.
def set_style(graphName,colour,minVal,maxVal,subgraph_x=None,subgraph_y=None)

# Add a value to a named graph in the output box
def on_value(graphName,value)

graphs.set_style

# graphs.set_style
def set_style(
    graphName,
    colour,
    minVal,
    maxVal,
    subgraph_x=None,
    subgraph_y=None
)

Set the style of a named graph in the output box.

Parameters

• graphName(str)
  The name of the graph, used to send values to it, and displayed on screen
• colour(str)
  The colour of the line, can be in the format “rgb(0,255,0)” or “red”, “blue” etc.
• minVal(float)
  The value of the bottom of the graph
• maxVal(float)
  The value of the top of the graph
• subgraph_x(int, optional)
  If you set x subgraphs, the graph window will be split horizontally from 0 to the maximum subgraph you set.
• subgraph_y(int, optional)
  If you set y subgraphs, the graph window will be split vertically from 0 to the maximum subgraph you set.

graphs.on_value

# graphs.on_value
def on_value(
    graphName,
    value
)

Add a value to a named graph in the output box

Parameters

• graphName(str)
  The name of the graph, which should be the same as passed to set_graph_style
• value(float)
  The value you want to add to the graph. If you add None, it doesn’t change the graph, this allows you to directly pass in the output of a `BlockAverageFilter` or similar which return None when there is no new value.
