Display numerical range and color scale in plots in diagram/ideogram and heatmap

[Optimistix]

Dear CNVkit team, thanks for creating such a wonderful tool.

While some of the CNVkit plota indicate the numerical range of the values plotted, the ideogram/diagram and scatterplots do not - is there any specific reason for this, and would it be possible to include a numerical scale in these plot types?

Thanks so much!

Hi @Optimistix,

Not an author of CNVkit, but I may answer your question => But 1st, could you confirm that when you say "numerical range of values plotted", you mean "log_ratio values" (generally y-axis in red/blue shades) => What you want is a colorbar as present to the left ot heatmap representatio ?

Thanks in advance. Have a nice day. Felix.

Hi @tetedange13 ,

Thanks so much for your response. Yes, what I want is a colorbar, with the numerical values as included e.g. with the scatter plot - log_ratio values would be convenient, in general the actual numbers corresponding to what's in the ideogram.

Thanks once again.

Best regards,

Rileen

Hi @Optimistix ,

• Regarding scatter plot, log_ratio values are actually represented by height of points (probes) and segments => No scale color implied here, so why you would need a colorbar ? => Maybe there is still something I misunderstandd in your question

• Regarding diagram plot, this is the only CNVkit representation that is not based on matplotlib => I am not at all an expert in Bio.Graphics (which is used), but it may simply be impossible to add such color bar with this module => Possible interesting note: found a Matplotlib-based implementation of ideogram
  

Hope this helped. Have a nice day. Felix.
