<h3><a NAME="Introduction"></a><b>Introduction</b></h3>
<p>This is a set of 32 bit Delphi components and classes for 2D plot. It is relatively
simple. It is more gauge then presentation element. The main features are:
<ul>
<li>Two horizontal and two vertical axis.</li>
<li>Auto minimum and maximum of the axis.</li>
<li>Swap of Min and Max axis positions. </li>
<li>MoveMinMax method to provide smooth scrolling of axis ticks.</li>
<li>Panning and Zoom by mouse.</li>
<li>Buffered screen paint, can be off.</li>
<li>Copy to clipboard as DIB or as Metafile.</li>
<li>Custom Data Series.</li>
<li>DrawPlot method to replicate plot image </li>
<li>OnDrawField OnDrawEnd events</li>
</ul>
<p>The main component is Tsp_XYPlot. It holds four Tsp_Axis and controls Data Series. The
Tsp_XYPlot and Tsp_Axis provide base plot functionality like auto scale, zoom and pan and
so on. The Data Series must be derived from Tsp_DataSeries and implements data storage and
how data are painted on the plot canvas. An example of these components are Tsp_XYLine and
Tsp_SpectrLines. Plot also can has and controls components inherited from Tsp_PlotMarker.
Plot marker draws something on the plot using axis coordinate system. An example of these
components are Tsp_LineMarker and Tsp_ImageMarker.</p>
