[Kst] Sparse Ascii data

[David McMinn]

Hi Nicolas,

When you say that Kst skips the point you should perhaps make it clear that it causes a gap in the line (it stops drawing at the previous point and starts drawing at the next point), rather than drawing a line directly from the previous to the next point.

Cheers.

Peter,

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?

Thanks,
Peter
