General
- Algebra View: options to sort by Construction Order & by Layer
Improved Tools
You can now just drag a shape to translate it
New Tools
New Functions
- psi(x)
The Digamma function
- polygamma(m, x)
The Polygamma function is the (m+1)th derivative of the natural logarithm of the Gamma function, gamma(x) (m=0,1)
New Commands
- Flatten[ <List of Lists> ]
- TriangleCenter[ <Point>,<Point>,<Point>,<Number> ]
- TriangleCubic[ <Point>,<Point>,<Point>,<Number> ]
- TriangleCurve[ <Point>,<Point>,<Point>,<Equation in A,B,C> ]
- Trilinear[ <Point>,<Point>,<Point>,<Number>, <Number>, <Number> ]
- Barycenter[ <List of Points>,<List of Weights> ]
- SurdText[ <Number> ]
- SurdText[ <Point> ]
- Function[ <List of Numbers> ]
First two elements of list are the min and max x-coordinates and the rest of the numbers are the y-coordinates (evenly spaced between x-min and x-max). Used by the Freehand Tool.
- BarCode[ ]
Searches for and decodes a barcode from the currently active Graphics View and creates a text if successful.
- BarCode[ <Image> ]
Searches for and decodes a barcode from the Image and creates a text if successful.
- BarCode[ "<Text>", "<Format (optional)>" , "<Error Correction (optional)>", <Width (optional)>, <Height (optional)>]
- BarCode[ <Number>, "<Format (optional)>" , "<Error Correction (optional)>", <Width (optional)>, <Height (optional)>]
Creates a barcode from the Text or Number. If the format is not specified then it will be guessed (eg as EAN_8, UPC_A, EAN_13 or QR_CODE) Possible values for Format are "AZTEC", "CODABAR", "CODE_39", "CODE_93", "CODE_128", "DATA_MATRIX", "EAN_8", "EAN_13", "ITF", "PDF_417", "QR_CODE", "RSS_14", "RSS_EXPANDED", "UPC_A". Possible values for Error Correction are "L", "M", "Q", "H".
JavaScript Methods
- registerLoggerListener(functionName), unregisterLoggerListener(functionName) to access Vernier Go!Motion USB Logger
- registerPenListener(functionName), unregisterPenListener(functionName) to handle pen tool usage
- drawToImage(label,x[],y[]), clearImage(label) to draw
- String evalGeoGebraCAS(String casCommand)
- String evalGeoGebraCAS(String casCommand, boolean printDebugInfo)
