l_move_grid {loon}

Arrange Points or Nodes on a Grid

Description

Scatterplot and graph displays support interactive temporary relocation of single points (nodes for graphs).

Usage

l_move_grid(widget, which = "selected")

Arguments

widget

plot or graph widget handle or widget path name

which

either one of 'selected', 'active', 'all', or a boolean vector with a value for each point.

Details

Moving the points temporarily saves the new point coordinates to the states xTemp and yTemp. The dimension of xTemp and yTemp is either 0 or n. If xTemp or yTemp are not of length 0 then they are required to be of length n, and the scatterplot will display those coordinates instead of the coordinates in x or y.

Note that the points can also be temporally relocated using mouse and keyboard gestures. That is, to move a single point or node press the CTRL key wile dragging a the point. To move the selected points press down the CTRL and Shift keys while dragging one of the selected points.

When distributing points horizontally or vertically, their order remains the same. When distributing points horizontally or vertically, their order remains the same. For example, when you distribute the point both horizontally and vertically, then the resulting scatterplot will be a plot of the y ranks versus the x ranks. The correlation on that plot will be Spearman's rho. When arranging points on a grid, some of the spatial ordering is preserved by first determining a grid size (i.e. a x b where a and b are the same or close numbers) and then by taking the a smallest values in the y direction and arrange them by their x order in the first row, then repeat for the remaining points.

Also note the the loon inspector also has buttons for these temporary points/nodes movements.
