The rubberband interaction provides an alternative way of zooming in Atlantis. Unlike the ZMR interaction ( 4.1 Zoom/Move/Rotate (ZMR)) you may exactly specify the region you are interested in by simply drawing a rubberband around that region. The interaction is activated for the current canvas pad by clicking on the Rubberband tab of the interaction control ( 3.1.3. Interaction Control) in the Control Window.
If rubberbanding is activated, the panel below the rubberband tab shows a box from which you may select a rubberband type:
Rectangle
Rectangle is specified by two opposite corners. Sides run parallel to the projection axes.
Rotated Rectangle
Rectangle is specified by two middle points of opposite sides. These points can be moved to change the orientation of the rectangle and the corners can be moved to increase or decrease the width of the rectangle.
Parallelogram
Parallelogram is specified by two middle points of opposite sides. These points can be moved to change the orientation of the parallelogram (the side with the opposite point remains fixed) and the corners can be moved both to change the orientation and to increase or decrease the width of the parallelogram (the two middle points remain fixed).
Square
Square is specified by the central point and by a corner. Preserves the aspect ratio of the picture.
X Skew
As parallelogram but with base side horizontally fixed.
Y Skew
As parallelogram but with base side vertically fixed.
X Slice
Vertical slice is specified by points on left and right side.
Y Slice
Horizontal slice is specified by points on left and right side.
Draw a rubberband in the current canvas pad by clicking and then dragging with the left mouse button on the picture. When you release the mouse button a pop-up menu will appear near your mouse.
Now you may re-adjust the rubberband by moving any of its corners or (if applicable) middle points.
There are two options to apply the current rubberband:
Zoom in the same canvas pad - Just click the Zoom button of the pop-up menu.
Zoom in some other canvas pad - Two options:
Drag the Zoom button of the pop-up menu into one of the canvas pads shown in the canvas control ( 3.1.2. Canvas Control) of the Control Window.
Drag the Zoom button of the pop-up menu into the target canvas pad directly (in the Canvas). This only works if at least some part of the target canvas pad is visible on the Canvas.
Rubberband Pop-up Menu
Table 4.2. Options of rubberband pop-up menu
Option | Action |
---|---|
Zoom | Zooms the selected region. |
New List | Shows the Lists pop-up window ( 3.3.4. Lists Window). |
Summarize | Information about the selected objects is displayed in the output display ( 3.1.5. Output Display) of the Control Window. |
Unzoom
After a rubberband has been applied, you may right-click in the canvas pad to get a pop-up Unzoom button. Click to undo the zoom. This works recursively.
Rubberbanding in φ/η
In the φ/η ( 5.2 φ/η Projection) projection only the rectangular rubberband is available. However in this projection the rubberbanding has additional functionality, which is described in Rubberband in φ/η Projection ( 4.2.1 Rubberband in φ/η Projection).
In the φ/η projection ( 5.2 φ/η Projection) only the rectangular rubberband ( 4.2 Rubberband) is available. However in this projection the rubberbanding has additional functionality which is available as extra options in the pop-up menu which appears when a rubberbanding operation is complete. These extra options are described in the following table:
Table 4.3. Additional rubberbanding options
Option | Action |
---|---|
Zoom LAr | Zooms the currently selected region, with the four samplings of the LAr calorimeter being shown in canvas pads 1-4, respectively. |
Zoom Calorimeters | As Zoom LAr, with additionally the two innermost samplings of the hadronic calorimeters being shown in canvas pads 5 and 6, respectively. |
Cut | Switch on the φ and η cuts, with the cut region set to that defined by the rubberband. If this Cut is dragged into another canvas pad the projection in that canvas pad is not changed. |
Whole Window | Sets the current zoom region to correspond to the whole canvas window. |
Print Contents | A short summary describing the tracks and the calorimetric energy inside the rubberband region is displayed in the output display ( 3.1.5. Output Display) of the Control Window. |
