Contour map gridded data visualizations using bokeh

Hi there,

I found one of your blog posts at http://webcache.googleusercontent.com/search?q=cache:R4ZzSKdHx9AJ:continuum.io/blog/bokeh-0.4.1+&cd=2&hl=en&ct=clnk&gl=us after searching for contour map visualizations using bokeh.

I have a list of NETCDF climatology files that I am attempting to plot and want to incorporate a time scrolling slider bar. Where can I find the example code for the contour plot example that used to be hosted on github?

I plan to use Xray and Bokeh to create this, but I don’t see the example code located anywhere. Was it removed?

If you have any info or tips that could help me out here that would be appreciated.

Thanks

aj

I didn’t know there used to be contour plots.

You can use matplotlib’s contour routines to get a collection of path objects, which can be rendered as lines. I’m working on creating filled contours by treating them as a set of closed polygons. This requires extracting paths from matplotlib’s contourf function and connecting interior holes to exterior domains. I’m using scipy’s delaunay and networkX’s graph to handle the connectivity.

Yes there was code examples of this Continuum talk on youtube but I can’t find it anymore. https://www.youtube.com/watch?v=B-P3yA-P-sY
Hoping for some help in searching around.

I just came across these examples from Continuum from Christine Doig
http://chdoig.github.io/scipy2015-blaze-bokeh/#/

She has links to the notebooks on

https://github.com/chdoig/scipy2015-blaze-bokeh

as well in the slides.

I am also trying to grid oceanographic data and if i get something working will post it here.

Good Luck,
