@YMorisawa how many columns does the frame you are working with contain? Could you share a sample dataset?

@mdymczyk Thank you for replying. The data contains 39 columns and the sample is very simple;

test.csv
column1,column2,...column39
1,2,3,...39

@YMorisawa right, the plot function in Flow does not take column names, you can only use one of our predefined values: label, type, Missing, Zeroes, +Inf, -Inf, min, max, mean, sigmna, cardinality, Actions.

For example:

plot (g) -> g(
  g.point(
  g.position "label","Missing"
)
  g.from inspect "columns", getFrame "Key_Frame__test.hex"
)

Would graph a plot based using Key_Frame__test.hex Frame, where the X axis would plot all the labels (column names column1,column2,...,column39) and the Y axis would show how many missing values are in each column.

For future reference - I think it's easier to use the plot function using the point and click FlowUI interface instead of writing it by hand.
