CDF3D
It displays 3D wireframed detector with tracks and hits.
If you want to rotate it, better switch option "SetDetailLevel" off.
To rotate use sliders or just type angles and press ENTER.

One more way to rotate is just to press "Pick" button from "Select Buttons"
group and rotate detector, using mouse.

There is a possibility to open CDF 3D window with specific detector
components - SVX, CLC, COT, CAL, TOF, CPR, SC, PASS, MUON
How to fo it:
Issue the following commands from the root prompt:

root [0] TCdfDisplay* d = new TCdfDisplay("SVX",TEdGeometry::SVX);
to show only SVX/ISL detector

root [1] TCdfDisplay* d = new TCdfDisplay("MUON",TEdGeometry::MUON);
to show only MUON detector

root [2] TCdfDisplay* d = new TCdfDisplay("CLC",TEdGeometry::CLC);  
to show only CLC detector

root [3] TCdfDisplay* d = new TCdfDisplay("CLC_SVX",TEdGeometry::CLC|TEdGeometry::SVX);
to show CLC and SVX detectors

COT

displays 2D X-Y view of the detector with:

o COT, Cmp, Cmu, Cmx, Xft, Si, Si3D hits 
o Calorimeter towers
o CDF, COT, XFT, SVT tracks
o Muon stubs
Mouse right-click options are:

ZoomIn - to Zoom in the picture
ZoomOut - to Zoom out the picture
UnZoom - to UnZoom the picture, if you UnZoom, you'll get the pad with default values
SetDisplayHits - Set display Svx,Cot, etc. hits.
SetDisplayXXXHits - Set display XXX hits
SetDisplayMuStubs - Set display muon stubs
SetDisplayTracks - Set display tracks
SetDisplayXXXTracks - Set display XXX tracks
SetDisplayDetector - Set display detector
etc...

RZ
Side view of the detector. There is only development version at the moment.
It is to display tracks, hits, towers from the side view.

MC
This is a Decay Tree display. Look at the example session here.

For the list of possible options click right mouse button.

SVX/ISL
It is a kind of CDF3D display.
It displays 3D SVX/ISL detectors.
To rotate it use sliders or just type angles and press ENTER.

Calorimetry LEGO plot - eta vs phi, available views:
ADC Counts
Uncalibrated non-pedestal-subtracted ADC counts versus eta vs phi
LEGO CalTowers E
Energy vs eta-phi
LEGO CalTowers E(accumulative)
Energy vs eta-phi accumulative histogram 
(each bin is a sum of energies of previous events) 
LEGO PhysicsTowers Et
Et vs eta-phi using information from transient object PhysicsTowerData, 
it has knowledge of interaction point position
LEGO PhysicsTowers E
E vs eta-phi using information from PhysicsTowerData

Lego plot shows Energy deposition in the PLUG detector. There are four available views for the PLUG EventDisplay:
WEST PLUG
In order to see histograms:
put PLUG Window in Pick Mode clicking on Pick select button.
Move cursor to the desired tower and click RIGHT mouse button 
Context menu pops up. Check Histograms function.
EAST PLUG
EAST PLUG - the same as WEST PLUG
WEST PPR
In order to see histograms:
put PPR Window in Pick Mode clicking on Pick select button.
Move cursor to the desired tower and click RIGHT mouse button 
Context menu pops up. Check plugShowerHists function.
EAST PPR
EAST PPR - the same as WEST PPR

Lego plot shows Energy deposition in the CES detector. There are two available views for the CES EventDisplay:
WEST CES
In order to see histograms:
put CES Window in Pick Mode clicking on Pick select button.
Move cursor to the desired tower and click RIGHT mouse button 
Context menu pops up. Check Histograms function.
Look at the example session here.

EAST CES
EAST CES - the same as WEST CES

CLC dedicated CLC monitor windows. There are two CLC monitor windows: East and West.
CLC West
CLC West detector window.

Press "Tower" button from "Select Buttons" group
Then click left mouse button on the tower to get the following
the information about channel ID and ADC.

Histogramming is incorporated into CLC Event Display:
     o  Profile Histograms ADC vs channel Id
     o  ADC counts vs channel Id
     o  ADC counts for each channel

In order to see histogram for specific channel:
put CLC Window in Select Tower Mode clicking on Tower select button.
Move cursor to tower, or its histogram bin and click right mouse button.
Context menu pops up.

Check Histogram function. Tower gets highlighted and its histogram
(accumulative) appears in separate window

In order to see profile histograms:
put CLC Window in Select View Mode clicking on View select button.
Move cursor to graphics field and click right mouse button. Context
menu pops up. Check Profiles function.
CLC East
CLC East detector window. It is similar to the CLC East window. 

BSC
There are two BSC parts in the BSC window: East and West.

Scale of colors for each channel:
     o  Light Green(30 in Root) - Data < 5.000
     o  Yellow(5)               - Data < 10.000
     o  Green(3)                - Data < 20.000
     o  Blue(4)                 - Data < 30.000
     o  Purple(6)               - Data < 50.000
     o  Dark Red(46)            - Data > 50.000

Press "Counter" button from "Select Buttons" group
Then click left mouse button on the counter to get the following
information about channel ID and ADC.

Histogramming is incorporated into BSC Event Display:
     o  Profile Histograms ADC vs channel Id
     o  ADC counts for each channel

In order to see histogram for specific channel:
put BSC Window in Select Counter Mode clicking on Counter select button.
Move cursor to counter, or its histogram bin and click right mouse button.
Context menu pops up.

Check Histogram function. Counter gets highlighted and its histogram
(accumulative) appears in separate window

In order to see profile histograms:
put BSC Window in Select View Mode clicking on View select button.
Move cursor to graphics field and click right mouse button. Context
menu pops up. Check Profiles function.

Look at the example session here.

TRIGGER
Information about Trigger Bits and corresponsing Triger names 
is available in this display.


Calorimeter
It is 3D view of central calorimeter with towers and tracks.
To rotate use sliders or just type angles and press ENTER.
One more way to rotate is just to press "Pick" button from "Select Buttons"
group and rotate picture, using mouse.

Control Panel
To get Control Panel press "Panel" button on the CDF ED Manager window.
There are 2 submenus - Loop and Myron Mode Flag.
At the moment submenu Myron Mode Flag is not fully implemented.
In the "Loop"  mode ED windows are updated for the next event automatically
after certain preset time period in seconds. 

To launch Loop mode
1) Click Panel button of ED Manager Window
2) Control Panel pops up. It has control buttons, text entry widget and
progress indicator.
3)Panel button of ED Manager Window gets grey, not allowing to open second
control panel
4)On Control Panel: 
	Click Loop button to start loop 
	Click Stop button to stop the loop 
	Enter Loop period in seconds in text entry widget. HIT ENTER
	for the change to make effect
Elapsed time is shown in progress indicator.
Ok button terminates the loop, closes Control Panel.
Cancel terminates the loop, closes Control Panel.
