URL parameters for just this file:

• x1 = # coordinate of first point when noresponse=1
• y1 = # coordinate of first point when noresponse=1
• x2 ... x20 = # subsequent coordinates when noresponse=1
• y2 ... y20 = # subsequent coordinates when noresponse=1
• extend = # sets the distance for the curve to extend (linearly) beyond the start and end points
• extendNonlinear = # sets the distance for the curve to extend beyond the start and end points
• extendNAN = 1 applies extension when NaN causes a a break between lines (default false)
• tau = # between 0 [linechart] and 1 [curve]. Default 0.5.
• intersections - state intersections of curves in alt text (default false)

Common URL parameters:

• debug=1 turn on console messages. Remember to remove it for production.
• xScale = pi
• xmin = left side of window
• xmax = right side of window
• ymin = bottom side of window
• ymax = top side of window
• xvar = variable name for horizontal axis
• yvar = variable name for vertical axis
• xRound = sets decimal places for rounding
• yRound = sets decimal places for rounding
• concavity = true describes the concavity for alt text (default false)
• oscillating = true describes oscillating for alt text (default true)
• pixelTolerance = 2 for alt text sets the number of pixels a curve can be away from an important (x,y)
• noresponse = 1 static graph without student response
• aspectratio - forces x units and y units to the same number of pixels (default false)
• breakUpTrig - parser option to cause asin to be changed to a*sin (default false)
• functionBeforePower - parser option to cause functions to be evaluated before powers (default true sin^2(x) = (sin(x))^2)
• sciNot - parser option to cause 3.1e-2 = 0.031 (default false 3.1e-2 = 3.1*exp(1)-2)
• booleanInequalities - parser option for 3*(x > 0) evaluated at x = 5 to be changed to 3*(5 > 0) = 3*(1) = 3. Primarily for Waner books. Useful for piecewise static graphs.
• EXP - parser option to allow all capital EXP(x) for exp(x). Primarily for Waner books.
