R plotly variable values tick distances to lower graph - r

Question

I hope I explain it correctly but I have 2 graphs in 1 plot (so 2 y-axes). I would like to have y-axis2 lowered, so thats it not plotted in the whole plot (so I guess have variable values for the same tick distances). How is this possible?
df <- data.frame(x = 1:50,
y1 = c(20:5,6:10,9:3,4:20, 19:15),
y2 = c(100:115,200:204,50:44,4:20, 66:62))
plot_ly(df) %>%
add_lines(type = 'scatter', mode = "lines",
name = "test",
x = ~x, y = ~y1,
line = list(color = '#999999'),
hoverinfo = "text",
text = ~paste(round(y1, 1), x)) %>%
add_lines(type = 'scatter', mode = "lines",
name = "test", yaxis = 'y2',
x = ~x, y = ~y2,
line = list(color = '#CC79A7'),
hoverinfo = "text",
text = ~paste(round(y2, 1), x)) %>%
#layout
layout(title = "test",
xaxis = list(titel = "Date",
rangeslider = list(thickness = 0.05)),
yaxis = list(side = 'left', title = 'test',
showgrid = F, zeroline = F, type = "log",
showline = T),
yaxis2 = list(side = 'right', overlaying = "y",
title = 'test',
showgrid = F, zeroline = F,
showline = T))

Answer 1

You can expand the axis with range and therefore lower the 200 position. And if you like to hide the values over 200, you may use ticktext and tickvals for showing just the values between 0 and 200.
plot_ly(df) %>%
add_lines(type = 'scatter', mode = "lines",
name = "test",
x = ~x, y = ~y1,
line = list(color = '#999999'),
hoverinfo = "text",
text = ~paste(round(y1, 1), x)) %>%
add_lines(type = 'scatter', mode = "lines",
name = "test", yaxis = 'y2',
x = ~x, y = ~y2,
line = list(color = '#CC79A7'),
hoverinfo = "text",
text = ~paste(round(y2, 1), x)) %>%
#layout
layout(title = "test",
xaxis = list(titel = "Date",
rangeslider = list(thickness = 0.05)),
yaxis = list(side = 'left', title = 'test',
showgrid = F, zeroline = F, type = "log",
showline = T),
yaxis2 = list(side = 'right', overlaying = "y",
title = 'test',
showgrid = F, zeroline = F,
showline = T,
# added code
range = list(0, 700),
tickvals = seq(0, 200, 50),
ticktext = seq(0, 200, 50)))
