<p><b>New page</b></p><div>Many discrete visualizations let you select data by clicking on the visualization. The effect of selecting data is to highlight the selected data in a different color in order to make it visually distinguishable. (You can change this color on the [[Row tab]].)<br />
<br />
Three data selection modes are available. You can change the selection mode on the [[Row tab]]. Not all visualizations support all selection modes; those that require a certain selection mode will always use that mode regardless of which mode you have activated on the [[Row tab]].<br />
<br />
The selection modes are:<br />
*'''Lasso selection''' - click and drag to draw an arbitrary boundary; points within this boundary are selected.<br />
*'''Box selection''' - click and drag to define the vertices of a rectangular boundary; points within this boundary are selected.<br />
*'''Point selection''' - click a single point to select it; you cannot drag to select additional points.<br />
<br />
In any selection mode, clicking an empty space on the visualization will deselect all data. In scatter plot-type visualizations, when using Lasso or Box selection mode, clicking a single data point (without dragging) will select that point as if you were using Point selection mode. <br />
<br />
The following keyboard combos can be used:<br />
*'''Shift + click''' - Add newly selected data to the current selection (union)<br />
*'''Alt + click''' - Subtract newly selected data from the current selection<br />
*'''Ctrl + click''' - Select data that was previously selected AND is newly selected (intersection)<br />
<br />
(Note that during ctrl+click selection, the previously selected points are unhighlighted. This may change in the future).<br />
<br />
You can also select data using the [[Main table]]. We are still working on getting keyboard combos to work correctly with the [[main table]]. The [[main table]] also allows you to select only a subset of the columns, which is useful for copying regions of your data table to the clipboard. For the purpose of highlighting data in visualizations, Rave considers a row of your [[data set]] to be selected if it is selected in any column of the [[main table]].</div>Admin
