The idea behind KPlotWidget is that you only have -to specify information in "data units"; i.e., the natural units of the -data being plotted. KPlotWidget automatically converts everything -to screen pixel units. - -KPlotWidget draws X and Y axes with tickmarks and tick labels. It -automatically determines how many tickmarks to use and where they should -be, based on the data limits specified for the plot. You change the limits -by calling setLimits( double x1, double x2, double y1, double y2 ), and -then calling updateTickmarks() to recompute the positions of tickmarks -and ticklabels. - -Data to be plotted are stored using the KPlotObject class. KPlotObject -consists of a QPtrList of DPoints, each specifying the X,Y coordinates -of a data point (DPoint is like QPoint, but the X and Y values are doubles -instead of ints). KPlotObject also specifies the "type" of data to be -plotted (POINTS or CURVE or POLYGON or LABEL). - -Jason Harris -kstars@30doradus.org diff --git a/libkdeedu/kdeeduplot/kplotaxis.cpp b/libkdeedu/kdeeduplot/kplotaxis.cpp deleted file mode 100644 index 69af4673..00000000 --- a/libkdeedu/kdeeduplot/kplotaxis.cpp +++ /dev/null @@ -1,32 +0,0 @@ -/*************************************************************************** - kplotaxis.cpp - An axis for the plot widget - ------------------- - begin : 16 June 2005 - copyright : (C) 2005 by Andreas Nicolai - email : Andreas.Nicolai@gmx.net - ***************************************************************************/ - -/*************************************************************************** - * * - * This program is free software;
