Answer 1

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{

        let identifier = "Custom"

        var cell: CustomCell! = tableView.dequeueReusableCellWithIdentifier(identifier) as? CustomCel  

          if cell == nil {
                tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: identifier)
               cell =tableView.dequeueReusableCellWithIdentifier(identifier) as? CustomCell
            }
          return cell
        }

d2 <- diamonds[diamonds$cut %in% c("Fair", "Good"),] %>%
  count(cut, color) %>%
  transform(color = factor(color, levels=rev(levels(color)))) %>%
  mutate(id = as.integer(color)) 

p <- plot_ly(d2, x = cut, y = n, type = "bar", group = color, xaxis = paste0("x", id), marker = list(color = c("#0000FF","#FF0000"))) %>%
  layout(yaxis = list(range = range(n), linewidth = 0, showticklabels = F, showgrid = T, title = ""),
         xaxis = list(title = ""))

subplot(p) %>%
  layout(showlegend = F,
         margin = list(r = 100),
         yaxis = list(showticklabels = T),
         annotations = list(list(text = "Fair", showarrow = F, x = 1.1, y = 1, xref = "paper", yref = "paper"),
                            list(text = "Good", showarrow = F, x = 1.1, y = 0.96, xref = "paper", yref = "paper")),
         shapes = list(list(type = "rect", x0 = 1.1, x1 = 1.13, y0 = 1, y1 = 0.97, line = list(width = 0), fillcolor = "#0000FF", xref = "paper", yref = "paper"),
                       list(type = "rect", x0 = 1.1, x1 = 1.13, y0 = 0.96, y1 = 0.93, line = list(width = 0), fillcolor = "#FF0000", xref = "paper", yref = "paper")))
