A value of (0,0) sets the upper-left corner of the text box to be at the position specified by setPos(), while a value of (1,1) sets the lower-right corner. *border* A pen to use when drawing the border *fill* A brush to use when filling within the border *angle* Angle in degrees to rotate text. Default is 0; text will be displayed upright. *rotateAxis* If None, then a text angle of 0 always points along the +x axis of the scene. If a QPointF or (x,y) sequence is given, then it represents a vector direction in the parent's coordinate system that the 0-degree line will be aligned to. This Allows text to follow both the position and orientation of its parent while still discarding any scale and shear factors. *ensureInBounds* Ensures that the entire TextItem will be visible when using autorange, but may produce runaway scaling in certain circumstances (See issue #2642). Setting to "True" retains legacy behavior. ================ ================================================================================= The effects of the `rotateAxis` and `angle` arguments are added independently. So for example: * rotateAxis=None, angle=0 -> normal horizontal text * rotateAxis=None, angle=90 -> normal vertical text * rotateAxis=(1, 0), angle=0 -> text aligned with x axis of its parent * rotateAxis=(0, 1), angle=0 -> text aligned with y axis of its parent * rotateAxis=(1, 0), angle=90 -> text orthogonal to x axis of its parent N)ranchor rotateAxisr __init__r QGraphicsTextItemtextItem setParentItem_lastTransform _lastScene dataBoundsrQRectF_boundssetColorsetTextsetHtmlfnmkBrushfillmkPenbordersetAngle) selftextcolorhtmlrr"r anglerensureInBoundss B/usr/lib/python3/dist-packages/pyqtgraph/graphicsItems/TextItem.pyrzTextItem.__init__sFFm ","4$% :K%!335  ##D)" "DO}} < MM% LL  LL JJt$ hhv&  ecL||j||j|y)z Set the text of this item.
