C++ TGaxis::SetName方法代码示例

///
/// Make a plot out of a 1D histogram holding a 1-CL curve.
/// The strategy is to always convert the 1-CL histogram (hCL) into
/// a TGraph. This way we can add known points (solutions, points
/// at end of scan range) and also have a filled area without line
/// smoothing. This is not possible with histograms due to a Root bug.
///
/// The function draws the TGraphs, and returns a pointer to the
/// TGraph object that can be used in the TLegend.
///
/// Markers are plotted if the method name of the scanner is "Plugin" or "BergerBoos" or "DatasetsPlugin".
/// One can plot a line instead of points even for the Plugin method by
/// using setPluginMarkers().
///
/// For the angle variables, a new axis is painted that is in Deg.
///
/// \param s The scanner to plot.
/// \param first
/// \param last
/// \param filled
