There is no chance that this will cause a problem due to sparse subgroup 
values? E.g. min_ctx is 5 and ctx is 500-510? This change certainly 
makes the charts a lot easier to understand, so it doesn't seem to be an 
issue. But it might be worth checking in the vis documentation if that 
is possible?

Otherwise...
