Histogram

• Get the state names with

  states <- l_info_states(h)
  names(states)

• Query a state, say showBinHandle, as follows

  h['showBinHandle']

• Change a state, say again showBinHandle, as follows

  h['showBinHandle'] <- FALSE

  alternatively, especially if you need to modify more than one state, use

  l_configure(h, showBinHandle=FALSE)

• When creating a plot you may specify any state at plot creation

  h1 <- l_hist(x=olive$oleic, showBinHandle=FALSE, yshows='density',
      color=olive$Area, showStackedColors=TRUE)

• details on a state, say showBinHandle, is easily had with

  states <- l_info_states(h)
  states$showBinHandle

  and a particular field

  states$showBinHandle$description

Good To Know

• When changing yshows to frequency or density per command line, you probably have to re-scale the plot as the y ranges of the histogram visualization changes

  l_scaleto_world(h)

When changing yshows via the inspector the rescaling happens automatically.

• When changing the bin handles when yshows is density the histogram is re-scaled every time the bin handle changes.

• The histogram display supports layers.
