+<li> Click an element of the tree hierachy on left panel to see/redefine the default plot options for selected element

+<hr>	
+<li><b><i>Page</i></b> :  self-explanatory;  <br/>
+        <i>Epoch Superposed Mode</i> : if activated  all time intervals        
+	(in a case of time table input) are plotted on the same page<br/> 
+	<i>Font</i> : all axis tickmarks; axis titles; copyright;

+	<li> <i>Vertical</i> : vertical stack of panels;<br/>
+	all time panels are of the same width;<br/>
+	one XY panel in the line;<br/>
+	generic panel height (for Time and XY panel)<br/>
+	and width (for XY panel) can be defined at this level
+	<li><i>Auto</i> : automatic layout - if possible combines<br/>
+	several XY panels at the same level;
+	only panel height can be defined (XY panel is 'square')

+	<br/>
+	Note : you can plot/save <i>Plot Template</i> : plot with empty panels 
+	(add and configure panels without parameters).<br/>
+	With <i>Prefered Dimensions</i> and <i>Font</i> options you may<br/> 
+	redefine generic setting for this particular panel.<br/>
+	<i>Background color</i> TBD to be defined for plot area only
+	<br/><br/>
+      
+      <ol><b>Plot types:</b> define plot type associated with the corresponding panel.<br/> 
+       Note that at the parameter level you specify parameter <i>Drawing Type</i>.<br/> 
+       For example on one <i>Time Plot</i> panel you may plot several parameters<br/>
+       with different drawing types (Serie, TickBar, StatusBar). 
+       
+       <li><i>Time Plot</i><br/>
+       permits different Drawing Types :  Serie, Spectro, Tick Bar, Status Bar  
+       
+	<li><i>Scatter (XY) Plot</i><br/>
+	permits Serie and Orbit Serie drawing types <br/>
+	Y = Y(X) plot; <br/>
+	parameter used as x is defined at parameter level by drag/drop from parameters tree.

+	<i>Orbit Serie</i> is a special type of XY Plot developed for orbits 2D presentations. 
+	<li><i>Epoch Plot</i><br/> 
+	Input - Catalog with 'CenterTime' Column 
+	
+	<li><i>Instant Plot</i><br/>
+	'instant spectrum' - 1D[2D] cut for 2D[3D] objects;<br/>
+	TBD : add option for interchange axis : Y => X; X => Y <br/>
+	Note: instant cut may be get also directly by right mouse click on spectrogram plot
+	
+	<li><i>Status Plot</i><br/> permits  only one drawing type - Status Bar.<br/>
+	TBD
+	
+	<li><i>Tick Plot</i> permits  only one  drawing type - Tick Bar.<br/>
+	Outputs parameter as tick values for major time ticks. <br/>
+	Note: BUG: for some time intervals <b><i>NaN</i></b> is output. Bug is known and will be fixed.
