What kind of visualizations do you use?  
If Lens of 7.9 or higher, there are Missing values option to fill gap.

> On an expression level, there is a new optional string argument \`fittingFunction\` on the \`lens\_xy\_chart\`, taking all available options. If no value is provided, it defaults to \`None\`, maintaining the old behavior - this means no migration is necessary, saved Lens visualizations will simply run an expression without a \`fittingFunction\` argument.
