Initialisation routine for the glowbit.matrix.graph2D object.
A graph2D object will be drawn to a rectangular region specified by the origin, width, and height.
This graph type is explicitly designed to draw time series data.
- Parameters
-
originX The x coordinate of the graph's origin (lower left corner). originY The y coordinate of the graph's origin (lower left corner). width The width, in pixels, of the graph's drawing area. height The height, in pixels, of the graph's drawing area minValue The value which will be mapped to the bottom edge. maxValue The value which will be mapped to the upper edge. colour A packed 32-bit GlowBit colour value. Used by the "Solid" colourmap, ignored by the "Rainbow" colourmap. Can also be accessed when writing custom colour map functions. bgColour A packed 32-bit GlowBit colour value which is drawn to the entire graph area prior to drawing the data. colourMap Either the string "Solid" or "Rainbow" or a pointer to a custom colour map function. Custom colour maps must take the parameters colourMap(self, index, minIndex, maxIndex). update If update=True then a call to updateGraph2D() will, in turn, call glowbit.pixelsShow() to update the physical LEDs.
