It is indeed the responsibility of the data source to decide what to do with missing data. The nice way to handle it is to return a NaN value, so that Kst skips the point when drawing the curve. I think we used to do this in Kst 1.x, and that's what we should do here.

Betreff: [Kst] Sparse Ascii data
Is there already a way to handle sparse Ascii data (data with missing values at some rows)?
N, Col1, Col2
1, 1, 2
2, , 2
3, 1, 2
The idea is to a have a plot for Col1 which is a horizontal line at 1 which does not draw down to zero at row 2.
Is it possible to set a "ignore this value" in the vector, or is it the responsibility of the data source plugin to not add a zero-value at such a entry when reading the file?
