seaborn.distplot allows seaborn.distplot to pass various parameters for styling ( *_kws ). Each chart function has its own parameters and therefore has a chart name prefix. For instance. the histogram has hist_kws . [ distplot link ]
Since the histogram chart is in matplotlib, we will need to look at the parameters of the keywords that we can pass. As you already understood, you can pass the keyword parameter "alpha" to get rid of the transparency of the lines. See Link for additional arguments (kwargs section). [ link to pyplot ]
