plot showing broken peak, not continuous

[wangxu1990]

Hi, thank you for this wonderful package that helped me a lot to visualize my chip-seq data.
Now I have no idea why the plot shows the broken peak as shown in the figure. My bigwig file was produced by deeptools bamcoverage with binsize 10 and smooth 30. Does it result from the big binsize? I guess not, because previously, I tried with another peak visualizing package, BioSeqUtils, https://github.com/junjunlab/BioSeqUtils, which gave me the non-broken plot.
Thank you!
