unsupported features from the r cookbook

Here are some remaining unsupported features as taken from the great ggplot2 cookbook.

The cookbook examples are in this branch: https://github.com/ropensci/plotly/tree/add-r-cookbook-tests, in this folder: https://github.com/ropensci/plotly/tree/add-r-cookbook-tests/tests/cookbook-test-suite

• TDH 23 Feb 2015 working on legend doesn't hide
  expected: http://www.cookbook-r.com/Graphs/Bar_and_line_graphs_(ggplot2)/bar-color-outline-nolegend.png

  actual:
  https://plot.ly/~ggplot2-cookbook/6/total-bill-vs-time/

  expected: http://www.cookbook-r.com/Graphs/Plotting_distributions_(ggplot2)/boxplot-fill-nolegend.png
  actual: https://plot.ly/~ggplot2-cookbook/56/rating-vs-cond/

  executable: https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/master/bars_and_lines.R#L28-L32, https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/a45f2c70b7adf484e0b0eb8810a1e59e018adbb8/distributions.R#L103-L106

  from: http://www.cookbook-r.com/Graphs/Bar_and_line_graphs_(ggplot2)/

  also see our polygons-borders test-case: http://grab.by/B8pa

  also see all of the examples that have a hidden legend by default, like "suppress y ticks labels and gridlines" from axes.R

• bar graph colors aren't right in this example
  see our cookbook example "basic bar fully styled"

• y-axis range
  expected output: http://www.cookbook-r.com/Graphs/Bar_and_line_graphs_(ggplot2)/line-point-ylim.png

  actual output: https://plot.ly/~ggplot2-cookbook/15/total-bill-vs-time/

• marker size is too small
  expected output: http://www.cookbook-r.com/Graphs/Plotting_distributions_(ggplot2)/boxplot-mean.png

  actual output: https://plot.ly/~ggplot2-cookbook/57/rating-vs-cond/

  code: https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/a45f2c70b7adf484e0b0eb8810a1e59e018adbb8/distributions.R#L116

  from: http://www.cookbook-r.com/Graphs/Plotting_distributions_(ggplot2)/

  compare also the ggplot-abline test in our github

  see also our test case "test-ggplot-size-global-scaling" and "test-ggplot-size-is-a-vector" and "test-ggplot-size-not-a-vector"

  see also our cookbook example "means-and-error-bars/within-subject-error-bars"

  also, too big in the example: "scatterplots/scatterplots colored by condition with extended regression line"

• facet text is positioned oddly
  annotations are positioned oddly -- maybe on plotly.js end or maybe on ggplotly end. also, the iframe is too small. in any case, looks pretty bad as a "show-off" example for facet support -- https://plot.ly/ggplot2/facet/

• suppressed y ticks, labels, gridlines
  see example from axes.R: "supress y ticks labels and gridlines"

  also: "hidden tick marks marks labels gridline"

• better placement of y-axis label for stacked facets
  see example from cookbooks "distributions/faceted-histograms"

• multiple density plots
  looks like our conversion works for a single density plot, but not for multiple density plots. see our example from cookbook "distributions/filled density plots" and "distributions/multiple density plots"

• colors of density plots
  see our example from cookbook "distributions/filled density plots". looks like "distributions/histograms" does the correct thing

• regression lines
  see cookbook example "scatterplots/scatterplots_colored_by_condition_with_extended_regression_line"

• add some more spacing around the graph: expand the range
  our range is flush against the domain of the axis, we might want to give the graphs a lil more breathing room, or explore just using plotly's autorange: http://grab.by/B8j6

  especially noticeable on this one: https://plot.ly/~TestBot/505/mpg-mean-vs-cyl/

  also this one: "basic line 2" from "bars-and-lines.R"

  also see our cookbook example "basic bar fill colors 1"

• geom_rect()
  Looks like this would be a cool one to add: http://stackoverflow.com/questions/17521438/geom-rect-and-alpha-does-this-work-with-hard-coded-values. An enterprise lead uses it and tried to re-make this plot today.

  https://plot.ly/~c_bort/5/test-for-matt-and-rich/

• histograms with date axis broken
  http://grab.by/B8oq

• legend position
  see our examples "legends/legend in bottom left" and similar

• re-orderding axes labels
  see http://www.cookbook-r.com/Graphs/Axes_(ggplot2)/#changing-the-order-of-items

  executable code: https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/master/axes.R

• reversed continuous scale
  expected output: http://www.cookbook-r.com/Graphs/Axes_(ggplot2)/bp_y_reverse.png

  actual output: https://plot.ly/~ggplot2-cookbook/82/weight-vs-group/

  executable code: https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/master/axes.R#L64-L66

  from: http://www.cookbook-r.com/Graphs/Axes_(ggplot2)/#reversing-the-direction-of-an-axis

• exponential notation
  http://www.cookbook-r.com/Graphs/Axes_(ggplot2)/sp_scale_log10_expticks.png

• legend background
  see our cookbook example "legends/box around legend"

• annotations
  http://www.cookbook-r.com/Graphs/Fonts/

• reverse legend
  actual output: https://plot.ly/~ggplot2-cookbook/96/weight-vs-group/
  expected output: http://www.cookbook-r.com/Graphs/Legends_(ggplot2)/bp-legendorder.png

  from: http://www.cookbook-r.com/Graphs/Legends_(ggplot2)/

  executable code: https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/master/legends.R#L23-L26

  see also our test "test-ggplot-stack" (although in that case, i think we're doing the correct thing)

• FIXED #167 scales="free" in ggplot2
  See: https://plot.ly/~zevross/18/staten-island-staten-island-staten-island-staten-island-staten-island-brooklyn-b/. It looks like we almost get it, but are using shared axes on two of them.

  ggplot(refdaylong, aes(date, value, color=variable)) + geom_line() + facet_wrap(~year, scales="free")

• graph outline
  expected output: http://www.cookbook-r.com/Graphs/Bar_and_line_graphs_(ggplot2)/bar2-final.png

  actual output: https://plot.ly/~ggplot2-cookbook/26/average-bill-for-2-people/

  code: https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/a45f2c70b7adf484e0b0eb8810a1e59e018adbb8/bars_and_lines.R#L146

• second set of error bars missing
  expected output: http://www.cookbook-r.com/Graphs/Plotting_means_and_error_bars_(ggplot2)/within-compare-errorbars.png

  actual output: https://plot.ly/~ggplot2-cookbook/44/value-vs-condition/

  executable code: https://github.com/chriddyp/ggplot2-plotly-cookbook/blob/a45f2c70b7adf484e0b0eb8810a1e59e018adbb8/means_and_error_bars.R#L340

  from: http://www.cookbook-r.com/Graphs/Plotting_means_and_error_bars_(ggplot2)/#understanding-within-subjects-error-bars

• log axes
  see "axes--log_10_y_axes_with_exponent_tick_marks" from the "axes.r"

• ln axes
  see examples: "ln y axes with visual equal spacing"
  we don't have "ln" axes, so should just do linear or "log" axes

• legend font
  see our cookbook examples "legends/styled legend labels"

• multi-line titles
  see our cookbook example: "graph with multi-line title"

• FIXED #213
  maybe ggplot2-bar-category-names should be a histogram: https://plot.ly/~TestBot/550 instead of a zillion stacked bars

• heatmap color scales
  http://grab.by/B8n6

• line type 4 should maybe just be dashed
  instead of dash-dot: http://grab.by/B8oG

• too many polygons?
  not sure whats going on in our bar chart for the test "polygons-springgreen3-lab: http://grab.by/B8qg

• text-size
  see test "test-ggplot-text": http://grab.by/B8r0

• shrink top margin when no title is supplied
  see our test "test-ggplot-theme-background"

• grid line colors (maybe all colors?) are just lil different
  see the grids in theme-ticks-and-grids test case

Inizia dagli elementi non selezionati in tests/cookbook-test-suite e dagli script cookbook indicati, come axes.R, legends.R e bars_and_lines.R. Riproduci una discrepanza circoscritta rispetto all'output atteso collegato, quindi aggiungi un test di regressione; «done» dovrebbe essere definito per comportamento e non per questa checklist generica.
