| 60 | // A QUICK Overview of the Event Display functions |
| 61 | // =============================================== |
| 62 | // |
| 63 | // The event display can ve invoked by executing the macro "display.C" |
| 64 | // A canvas like in the picture below will appear. |
| 65 | // |
| 66 | // On the left side of the canvas, the following buttons appear: |
| 67 | // *Next* to move to the next event |
| 68 | // *Previous* to move to the previous event |
| 69 | |
| 70 | // *Pick* Select this option to be able to point on a track with the |
| 71 | // mouse. Once on the track, use the right button to select |
| 72 | // an action. For example, select SetMarkerAttributes to |
| 73 | // change the marker type/color/size for the track. |
| 74 | // *Zoom* Select this option (default) if you want to zoom. |
| 75 | // To zoom, simply select the selected area with the left button. |
| 76 | // *UnZoom* To revert to the previous picture size. |
| 77 | // |
| 78 | // slider R On the left side, the vertical slider can be used to |
| 79 | // set the default picture size. |
| 80 | // |
| 81 | // When you are in Zoom mode, you can click on the black part of the canvas |
| 82 | // to select special options with the right mouse button. |
| 83 | |
| 84 | // |
| 85 | // When you are in pick mode, you can "Inspect" the object pointed by the mouse. |
| 86 | // When you are on a track, select the menu item "InspectParticle" |
| 87 | // to display the current particle attributes. |
| 88 | // |
| 89 | // You can activate the Root browser by selecting the Inspect menu |
| 90 | // in the canvas tool bar menu. Then select "Start Browser" |
| 91 | // This will open a new canvas with the browser. At this point, you may want |
| 92 | // to display some histograms (from the Trees). Go to the "File" menu |
| 93 | // of the browser and click on "New canvas". |
| 94 | // In the browser, click on item "ROOT files" in the left pane. |
| 95 | // Click on galice.root. |
| 96 | // Click on TH |
| 97 | // Click on TPC for example |
| 98 | // Click on any variable (eg TPC.fX) to histogram the variable. |
