Arguments

Argument Description Example Default
Plots Plots as JSON See #Example
From Lowest x,y to plot -pi/2,0 0,0
To Highest x,y to plot 10^2,2
Origin X/Y Axis origin 0.5,0.5 0,0
GridStep Coordinate grid step size pi/2,1 1,1
Inline Display the plot inline instead of floating true (absent)
LabelX, LabelY Axis label (not implemented)
LabelStepX Label for grid X-axis increments format("%sπ", dfrac(x/pi, 1)) format("%d", x)
LabelStepY Label for grid X-axis increments format("%.1f", y) format("%d", x)
ColorX X-axis color #44f #f44
ColorY Y-axis color #0f4 #0f0

Underlined Arguments are required.

Available Functions and Constants in Expressions

  • printf(format, ...args)
    See Lua string.format.
  • dfrac(number, is_factor)
    Formats a float as a fraction, if possible. If it is a factor, then the number 1 or -1 will only produce its sign as an output, useful when formatting as a factor of pi, for example. See #Example below.
  • sin,floor,abs,...
    Any constant or function from the Lua math library can be used directly (without the math. prefix).
