Bar View

Bar view is the central working display of the Variorum edition. It provides an online workspace allowing you to compare individual bars or ranges of bars from across some or all of the sources for a given work within the OCVE database. Bar view also allows you to look at the critical apparatus and create annotations of your own if you have registered with the website and logged in. Note that bar view does not currently allow comparison of bars from different works.

The basic bar view display appears as follows (this is what you will see the first time you click the Add source to bar view icon beside an individual source in the tree display).

Basic controls

  1. Summary information about the currently visible work, including the bar number, is clearly displayed here.
  2. The next / previous arrows allow you to move in sequence through the bar images of the currently selected source(s).
  3. The Select Bars menu allows you to quickly jump to a different bar within the work you are currently viewing. This may often be quicker than moving sequentially through the individual bars.
  4. The Display options allow you to customise the way bar view is displayed.
    1. Number of visible bars: You can choose to display anywhere between one and four bars in sequence at a time. The default setting is '1 bar'. A thick black vertical line between bars will be shown where a sequence of bars includes a new system or new page. Note that choosing the three- or four-bar display together with a large number of sources will make bar view less responsive when you select a different bar.
    2. You can customise the visible sources. The list of sources displayed here corresponds with the options available to you in the browse panel. You can either add new sources to the display individually (by checking the boxes in this list), or use the 'toggle all' menu item to show all of the available sources at one time. Note that the 'toggle all' function may be slow to respond when a large number (more than 10) of sources is available.
    3. The Labels check box toggles the display of labels (and toolbars) on all of the individual bar images.
    4. The Fullscreen option hides the navigation and the browse panel to make more space available for the bar display. This can be useful if you are working on a small screen or if a large number of bar images is displayed.
    5. Reset will completely redraw the display, resetting any customisations you have made and snapping the bar images back to a 'grid'.
  5. Bar images. By default the bar images are displayed in a fixed 'grid', but each individual bar image is draggable. You can arrange the bar images onscreen in whatever way you wish to aid comparison. Note that if you rearrange the display your settings are remembered when you use the next / previous bar function, or jump to a different bar using the 'Select bar' menu. However, your customisations will be lost if you work with a different piece or use the Display Reset function (see above).
  6. Moving your mouse over an individual bar image reveals an Information icon. Clicking this shows the label and toolbar for that bar. The label show brief source information for the bar including the source descriptor. The toolbar functions are detailed below.

Bar labels and toolbar

  1. Magnify bar image: clicking here opens a larger version of the individual bar image, thereby allowing closer study. The individual bar image opens in a popup window and the screen darkens; next and previous buttons allow you easily to cycle through magnified images of each of the bars currently displayed in bar view.
  2. View full page: allows you to switch to the Full Page / Bar Selection view to see the full page from which the individual bar is taken. Note that clicking this button takes you away from bar view.
  3. View notes for this bar (where available): where a bar has commentary from the OCVE team or from individual users associated with it, this icon will be shown, together with a number indicating the number of notes. Clicking this button switches the browse panel to notes view.
  4. Add a note to this bar (visible only to logged-in users) allows you to add your own comment to a bar. Clicking this button switches the browse panel to notes view.
  5. Remove source: allows you to remove a source from the bar view display (removing the bar image). Should you wish to restore the source, or remove several sources quickly, use the Visible sources dropdown menu at the top of the screen (see Basic controls, 4b, above).
  6. Hide label: removes the label / toolbar overlay from the bar image.
