My problem is expressed on [Google Group](https://groups.google.com/a/continuum.io/forum/#!searchin/bokeh/london/bokeh/iKBPrpsqKso/Ou5jbFk4DcgJ), where I link to the repository branch where I am building the map (it's a flask application but the only files of interest are static/london_fci.html , london_postcodes.py and charts.py\r\n\r\nTLDR:\r\nThe longitudes of London are very small, very close to 0 for the obvious proximity to Greenwich, I find that all my longitudes are being converted from floats to exponential numbers, causing some postcodes to appear in totally wrong longitude. \r\n\r\nAny help, advise is greatly welcome!"}}
