combobox / spinbutton / slider / toggle

scrollbar?

for lattice plots can probably use auto.key

otherwise need to pop up a dialog to set up legend.

Menu to choose to copy as PNG or WMF (windows only).

also think about how to manage a user-contributed library of tools.
need to have auto-detection of where the button can be used.

probably can do it with the viewport argument,
but should be able to detect it automatically.
(haven't tried it yet)

If "keep" function is active,
* switch to another device when the window loses focus
  (to avoid plot.new etc using the device);
* confirm when window is closed.

(support a+b+c on left side of formula)

options for "identify":
- identify single points or whole regions
- show ID or value or both
- save current IDs to object
- find in IDs (as regexp)

i.e. col = with(dat, Variable)
use current lattice regions palette?
add colorkey?

automatically generate data.points

need API for handling new plot types.

how to identify a plot call
- by high level plot function?
- by data class?

user-space functions to give x y coords and labels.

also -- specify how to zoom (set xlim / ylim)?

example maybe: graph

if it is a lattice plot and either
- a simple trellis object is passed rather than a high-level plot call; or
- can not find an appropriate high-level call to accept arguments;
then wrap it in update() and use that as mainCall.

(like in the index text box)

eg if class(index(x)) is "Date" then
as.Date(c(6113.421903, 8374.758816))

if "POSIXct"
ISOdate(1970,1,1,0) + c(100000, 1000000000)

using tooltips?

add GTK color selection widget to style dialogs

see demo("colorSelector")

also allow this widget to be generated by a 'parameter' given as a hex
color code ("#0099AAFF")

plot settings: edit strip text

Is a nice click+drag interface possible?
Does it interfere with locator()?
Maybe need to do locator / identify manually.

Then can zoom / identify etc with one click+drag.
Do not need to click to choose panel.

is there a dendrogram plot that can be zoomed?
maybe need to write one using latticeExtra::dendrogramGrob.

(currently broken)

have not tried it yet...

re lattice:
"full scale" should apply only to continuous scales.

static status bar
"Click to identify points. Drag to zoom in (hold arrow keys to constrain
x/y). Right-click to zoom out."

with option to remove it.

how to do this elegantly?

should probably allow the default actions to be customised.

demonstrating API and writing new tools?

Make a tab / notebook interface.

Allow user-extensible settings (new tabs).

Settings for:
decorations etc.
superpose (lattice)
layers?

Dialog not modal.

store plot data object centrally

(from 'data' argument, or maybe check stored objects for matching NROW)
(or could be extra variables in data.points structure?)

otherwise just a list with $x and $y

if data object has other variables, allow these to be used as ID labels.

"z" variable: levelplot / etc / panel.triangulate

2 variables on x (or value + error?): 
segplot
 +"level" argument gives covariate (color)

Can grab Cairo device and scale it up to zoom any plot?

Some way to export the main plot data as a text file.
Or perhaps save it to an R object in the workspace.

i.e. synch IDs / brushed

like lattice.options?

for simple redraws such as removing/editing labels,
or removing/editing annotations:

look at using either
  - recordPlot / replayPlot; or
  - saved GdkDrawable buffer

to redraw quickly.

right click:

with lattice plots, use trellis.vpname and test click inside:
"panel" +col +row
"strip" +col +row (and "strip.left")
"main", "sub", "xlab", "ylab"
"legend" +side
otherwise: maybe xaxis / yaxis

for base graphics:
maybe "main" if above plot / "yaxis" if left of plot" / "xaxis" if below
plot...

if go back (with back button) to a previous plot,
then do something new,
the later history should be deleted
(as in a web browser).

Maybe look at handling very large datasets by
  - sampling
  - binning: levelplot / hexbin
  - summary stats like boxplot?

It is a bad idea to try to plot them, since lots of copies of the data end
up being made:
  - playState$trellis
  - grid display list
  - base display list
  - etc?

Is this possible?
Does event handler interfere with locator?

smart label placement using optimisation to avoid overlaps.

But seems to be very slow.

lots of good ones in DAAG package, with examples.

gwidgets is too slow -- use GTK / glade instead

for:
- add annotation
- edit annotations
- edit call
- plot settings

test "basic device mode"

in multi-panel lattice plots:
- if zoom inside a single panel, should expand that panel as well as zoom.
  (but not in time.mode)
- if scales$relation is not "same", then set scales$xy$limits to a list
(treat "sliced" as "free").
- if zoom box contains several panels, use indexing to select them (but
what about mainCall?) -- or set layout + page?

Time mode text-box (current x-axis limits) should be formatted as the data
class: POSIXct, Date, integer or numeric.

Also need to handle special case of time.index... (user-specified discrete
times) gui provides integer current.index and time current.time in $env.

can unify?

drag on 3d plot:

draw line during drag.
rotation around x ~ y drag vector (drag down --> x= ++)
rotation around y ~ x drag vector (drag right --> y= ++)
- prepend to screen=list()

+ TODO: identify points in cloud()

What steps will reproduce the problem?

What is the expected output? What do you see instead?


Please use labels and text to provide additional information.

allow setting size of exported image: in/cm/px

bitmap( , type="pdfwrite")
 -- depends on GhostScript --
makes a compressed PDF?

(blue sky...)

from Gabor:

for grid-based graphics the ability to query individual graphic
subobjects to find out their names and other properties and
to change their property values dynamically.  (Note that
its currently possible on Windows to copy a graphic using
Microsoft metafile format into Word and then use Word's
vector graphics editing capability to modify objects in the
graphic but this would allow that right in R.)

What steps will reproduce the problem?
1. Install playwith (download, then install.packages("playwith"))
2. library(playwith)
3. autoplay(lattice=T)
4. xyplot(Sepal.Length ~ Sepal.Width | Species, data=iris)

What is the expected output? What do you see instead?

The pot is fine, but I get error message in the console :
Error in playState$call[["data", exact = TRUE]] : 
        nombre d'indices incorrect

Please provide any additional information below.

drag should zoom in, so don't need tool on toolbar.
right-click should zoom out.
(similar behaviour to SAGA / iplots)

maybe should have some tools as toggles, so by default in "zoom mode", can
switch to "annotation mode" or "selection mode" or whatever...

Can not always assume that the outer call is where arguments should go.
E.g.1. if the plot call is wrapped in "with" or similar, arguments apply to
the inner call. 
E.g.2. qplot(...) + geom_line()
