Member Function Documentation

double TxqLinLogViewPort::pixelToX ( const QPoint & p ) [virtual]
 

Convert the pixel to the plot x value.

Parameters:
p   the pixel point.
Returns:
the plot x coordinate for a given screen pixel p.

Reimplemented from TxqLogViewPort.

void TxqLinLogViewPort::setXmax ( double val ) [virtual]
 

set the X maximum value of the plot region.

Parameters:
val   the value for the right edge of the plot.

Reimplemented from TxqLogViewPort.

void TxqLinLogViewPort::setXmin ( double val ) [virtual]
 

set the X minimum value of the plot region.

Parameters:
val   the value for the left edge of the plot.

Reimplemented from TxqLogViewPort.

short TxqLinLogViewPort::xToPixel ( double x ) [virtual]
 

Convert the x coordinate on the plot to a x pixel value.

Larger valued x pixels are to the right on the screen.

Parameters:
x   the plot coordinate x
Returns:
the x pixel

Reimplemented from TxqLogViewPort.
