Detailed Description

a speed optimized plotter class

Deprecated:: The class JKQTFastPlotter and all its support classes are deprecated and will be removed in future versions.

This plotter class is (in contrast to JKQTPlotter) optimized for speed. It allows to plot function graphs/data in a simple manner. The focus of design was not on a nice output (athough this is not unimportant), but on the speed of the output. So the class may be used to di quick plotting of data, i.e. in fast image sequence applications.

These measures were taken to increase speed:

The coordinate system is drawn onto an internal image which is only updated, when the size of the widget or a property of the coordinate system changes. When only the data changes, just the data plot has to be updated.
The class uses an internal buffer with the complete image, so a repaint does not always trigger a complete repaint of all elements, but just measns painting the internal image to the screen. This also allows to plot selections ... over the plot, without having to replot the plots.
The definition of the coordinate system as well as the definition the system ticks ... is reduced to the absolute minimum.
The method setPlotUpdateEnabled() allows to prevent replotting of the class contents, e.g. when you want to set a multitude of parameters without triggering a replot every time.

The class supports these features:

coordinate axes may be linear or logarithmic.
ticks and tick labels are drawn by a simple algorithm: The user has to supply two values: zeroTick is a tick value that exists in any case (i.e. 0) and tickDistance which contains the distance between two ticks (only applicable to linear axes). Then the class starts to draw at zeroTick and move on to zeroTick+tickDistance and zeroTick-tickDistance until min / max of the axis is reached. For logarithmic axes the class uses zeroTick*10 and zeroTick/10
plot may contain a grid (x and y grid may be switched on/off separately).
plots are represented by descendents of JKQTFPPlot and the plotting code is completely contained therein (and should be speed optimized).
it is possible to keep a specified aspect ratio
it is possible to couple different plots in a way, that they are plottetd with the same width/height both in pixel and world coordinates by using plotterSizesChanged() and synchronizeX() / synchronizeY().
