I would love to see this feature coming so that our internal F# and Python notebooks can be viewed and shared easily on VSTS.

Please provide a more detailed repro. Thanks.

Post my SO answer here. Does this solve your problem? To use `zip`, both frames will match column by column and add two series together. In your case, `divFrame` has...

That's fair. A different solution. `addFunc` is to deal with missing values in `s2` ```fsharp let addFunc (s1:Series) s2 = s1.Zip(s2, JoinKind.Left, Lookup.Exact) |> Series.mapValues(fun (x, y) -> x.ValueOrDefault +...

Sorry for proposing the second solution that did not solve the problem. I agree that `zip` is confusing to use. Let me take some time to look into the design...

@tpetricek I'd like to revisit this issue. Pandas library comes with built-in functions such as df.cov to calculate covariance matrix. Pandas has dependency on numpy. Shall we add dependency of...
