Parallel coordinates and missing data

[visualizer-feedback]

We are currently generating dynamically parallel coordinates but when feeding new input array sometimes some properties are missing either in the first record or all together.

Currently the parallel coordinates crash if in the first object all the properties are not present.

Moreover is a property is not present in any of the records the selector should just disappear.

most of these issues are with the parcoord library itself. I'll look into it when I have time

I think the data could be filtered before injecting them in the parallel coordinates library

if a property is not present in any record, how can you select the jpath in the first place ?

Because the input array change.

So I was able to select, then change the array, then it crash.

I have the problem with the petroleomics project

you can't remove the missing column in the preferences ?

No because it changes depending the input array that is resulting from an output variable of a "mouse over" of a slick grid.
