Hi,

I’m still new in bokeh.
I’m currently building on a visualization project with some discrete points,
such as x = arang(0,36,1) y = [0,0.5,4.8,5…(28)…5,4.8,0.5,0]，I use
Then run this code I got a line chart, but I want to plot a smooth cruve
How can I fit the cruve to make it smooth.

Thanks a lot

Hi,

This is not really a Bokeh question. In general, if you want the visualized curve to be more "smooth" then you need to show more points. In your code you have 35 x,y values. Depending on how "smooth" you want, you might want to increase that to several hundred x,y values. If this data came from some synthetic source, then hopefully you can just create more points (as many as you want). If these data are measurements, and you can't get or make additional measurements, then you will have to do some kind of interpolation. But Bokeh does not have anything built in for interpolation. For one thing, the right kind of interpolation is dependent the particulars of a user's situation, which we don't know anything about in general. To learn more about interpolating with Python you'd want to google search for "numpy interpolation" or "scipy interpolation", since numpy and scipy are the other different projects that would have functions to help you interpolate.

Thanks a lot for your answer, I will learn more about Python to achieve this goal.

Finally, I am very sorry for not timely feedback, because the Great Firewall in China.
