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 tick marks and tick labels. It +automatically determines how many tick marks 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)`. + +Data to be plotted are stored using the KPlotObject class. KPlotObject +consists of a QList of QPointF's, each specifying the X,Y coordinates +of a data point. KPlotObject also specifies the "type" of data to be +plotted (POINTS or CURVE or POLYGON or LABEL). |
