Remove marker border/line in scatterplot plotly R-CodePudding

This is my code:

BD_mapinc <- plot_ly(BD_tab, x=~East, y=~North, type='scatter', mode='markers',
                      text= ~paste("BD incr:", BD_tab$BD_incr, "No.:", Label),
                      size= ~BD_tab$BD_incr,
                      marker=list(color = ~BD_tab$BD_incr,
                                  colorbar=list(title='BD increment [%]'),
                                  colorscale='PuOr')
                      ) %>%
      layout(plot_bgcolor='#e5ecf6', 
             xaxis = list( 
               zerolinecolor = '#ffff', 
               zerolinewidth = 2, 
               gridcolor = 'ffff'), 
             yaxis = list( 
               zerolinecolor = '#ffff', 
               zerolinewidth = 2, 
               gridcolor = 'ffff'))
)
      
BD_mapinc

Ever since I found out how to add a title to the colorscale with the marker option, I also have unwanted marker borders. Can someone help me? How can I remove them? What the plot currently looks like

CodePudding user response：

You can move some of your arguments into the marker function and set line width to zero to remove the lines around the markers:

BD_mapinc <- plot_ly(BD_tab, x=~East, y=~North, type='scatter', mode='markers',
                     text= ~paste("BD incr:", BD_tab$BD_incr, "No.:", Label),
                     marker=list(color = ~BD_tab$BD_incr,
                                 colorbar=list(title='BD increment [%]'),
                                 colorscale='PuOr',
                                 size= ~BD_tab$BD_incr,
                                 line=list(width=0)))%>%
  layout(plot_bgcolor='#e5ecf6', 
         xaxis = list( 
           zerolinecolor = '#ffff', 
           zerolinewidth = 2, 
           gridcolor = 'ffff'), 
         yaxis = list( 
           zerolinecolor = '#ffff', 
           zerolinewidth = 2, 
           gridcolor = 'ffff'))
