          <p>2. Have at least one series implementing GetNearestPoint interface
(by default it is implemented by line, bar and area series);</p>
          <p>3. Have <link id="TASeries.TBasicPointSeries.UseReticule">UseReticule</link>

          <p>Chart methods work with two coordinate systems: floating-point coordinates supplied by series (often called <i>graph coordinates)</i> and on-screen coordinates (often called <i>image coordinates</i>)</p>
