Set the aspect ratio of a plot

The aspect ratio is defined by the ratio of the number of pixels for one data unit on the y axis and the number of pixels for one data unit on the x axes.

l_aspect(widget) <- value

Arguments

widget	widget path as a string or as an object handle
value	aspect ratio

Details

Changing the aspect ratio with l_aspect<- changes effectively the zoomY state to obtain the desired aspect ratio. Note that the aspect ratio in loon depends on the plot width, plot height and the states zoomX, zoomY, deltaX, deltaY and swapAxes. Hence, the aspect aspect ratio can not be set permanently for a loon plot.

Examples

p <- with(iris, l_plot(Sepal.Length ~ Sepal.Width, color=Species))

l_aspect(p)
#> [1] 0.4562569
l_aspect(p) <- 1
