Bokeh plot conditional background colour

Community Support

Hi everyone

I am trying to replicate the graph I attached (done with Matplotlib) where the background colours on the graph represent some genomic coordinates. My data is set in a pandas DataFrame and I have two columns in the DF to indicate grouping/boundaries between all regions. I have many genes to plot, and all of them have a completely different pattern.

The columns look like these

chr7:EZH2:1411 chr7:EZH2:1411_148504773_148504823
chr7:EZH2:1412 chr7:EZH2:1412_148506148_148506198
chr7:EZH2:1412 chr7:EZH2:1412_148506198_148506248
chr7:EZH2:1412 chr7:EZH2:1412_148506248_148506298
chr7:EZH2:1413 chr7:EZH2:1413_148506387_148506437
chr7:EZH2:1413 chr7:EZH2:1413_148506437_148506487
chr7:EZH2:1413 chr7:EZH2:1413_148506487_148506537
chr7:EZH2:1414 chr7:EZH2:1414_148507410_148507460
chr7:EZH2:1414 chr7:EZH2:1414_148507460_148507510
chr7:EZH2:1414 chr7:EZH2:1414_148507510_148507560
chr7:EZH2:1415 chr7:EZH2:1415_148508702_148508752
chr7:EZH2:1415 chr7:EZH2:1415_148508752_148508802
chr7:EZH2:1415 chr7:EZH2:1415_148508802_148508852
chr7:EZH2:1416 chr7:EZH2:1416_148511036_148511086
chr7:EZH2:1416 chr7:EZH2:1416_148511086_148511136
chr7:EZH2:1416 chr7:EZH2:1416_148511136_148511186
chr7:EZH2:1416 chr7:EZH2:1416_148511186_148511236
chr7:EZH2:1416 chr7:EZH2:1416_148511236_148511286

So all tagged with 1411 will have a green background, all tagged with 1412 will have a green background and 1413 will be green, and so on. I understand the BoxAnnotation might be the best option here, but I am failing to convert the columns I have into something meaningful that will cover many different patterns.

Thanks in advance, any help appreciated.

Cheers

Paulo

Hi Paulo,

I am glad to hear that you were able to find a solution. It would be appreciated if you could share at least a summary of what you found out, for the benefit of other users who may come across this question.

Thanks,

Bryan

Hi Brian

Thanks, this was my first reply from this list. I think it’s quite useful to post a solution to some problem, especially for other people with similar issues.

In my case it was quite simple, I got the column from the pandas DataFrame and iterate over it to add to a list to the BoxAnnotation.

Simple.

Thanks

Paulo
