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. I didn’t find answer in bokeh doc, so I hope solve this problem in here.

Thanks a lot :slight_smile:

The only thing you can do to make it more smooth is to increase the number of points. You are currently using 36 points, but for the smoothness that you want, you’ll need 1 point per pixel. So, if your chart is 500 pixels wide, you’ll need x = linspace(0, 35, 500). (Of course, this assumes that the numerical domain of your function is [0,35].)

I’m not sure how you generated your Y values, but you’d need to regenerate them, or define a Python function which can actively and dynamically generate the values as you zoom.

Thanks a lot for your answer. Now I have already known bokeh don’t have a function like “spcrv” in matlab, I will try to learn about interpolation with Python.

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