When I plot the centrality of the Isle of Wight road network, it seems different with the map as shown in document.I found that the legend is in this format: "0min to 1min..." , while the example legend is: "0 to 73.215...".

I try to double check my centrality centrality_sf dataframe,it include 'centrality' and the unit is not min.

My code is as following:
tm_shape(centrality_sf) +
tm_lines(lwd = "centrality",col = "centrality", scale = 4,palette = "-viridis")

How can I solve this?Thank you.

Not sure how you can solve that @Haode-Sun. Maybe you could set breaks manually with breaks = c(0, 1000, 100000) for example? Great job on opening an issue and cc @mem48.

I think in the example i used jenks to set the breaks. Also the mln is short for million and is just tmap trying to be helpful by simplifying the legend

You also seem to have a lot more roads. Did you miss the filter stage?
