Using the xlab and the ylab arguments, we can add labels to the X and Y axes of the bar chart. In the previous code block we customized the barplot colors with the col parameter. Lets create a simple bar chart in R using the barplot() command, which is. We can specify in the range 0 to 255 with the additional argument max255. This function returns the corresponding hex code discussed above. Df = '' ) # colors column for increasing and decreasing for ( i in 1 : length ( df )) i % plot_ly ( x = ~ Date, type = 'candlestick', open = ~ AAPL.Open, close = ~ AAPL.Close, high = ~ AAPL.High, low = ~ AAPL.Low, name = 'AAPL', increasing = i, decreasing = d ) fig % add_lines ( x = ~ Date, y = ~ up, name = 'B Bands', line = list ( color = '#ccc', width = 0.5 ), legendgroup = 'Bollinger Bands', hoverinfo = 'none', inherit = F ) fig % add_lines ( x = ~ Date, y = ~ dn, name = 'B Bands', line = list ( color = '#ccc', width = 0.5 ), legendgroup = 'Bollinger Bands', inherit = F, showlegend = FALSE, hoverinfo = 'none' ) fig % add_lines ( x = ~ Date, y = ~ mavg, name = 'Mv Avg', line = list ( color = '#E377C2', width = 0.5 ), hoverinfo = 'none', inherit = F ) fig % layout ( yaxis = list ( title = 'Price' )) # plot volume bar chart fig2 % plot_ly ( x =~ Date, y =~ AAPL.Volume, type = 'bar', name = 'AAPL Volume', color = ~ direction, colors = c ( '#17BECF', '#7F7F7F' )) fig2 % layout ( yaxis = list ( title = 'Volume' )) # create rangeselector buttons rs % layout ( title = paste ( 'Apple: -', Sys.Date ()), xaxis = list ( rangeselector = rs ), legend = list ( orientation = 'h', x = 0. It is possible to add a title to the graph by using the main argument. The function rgb () allows us to specify red, green and blue component with a number between 0 and 1.
