jScope won't display any data if there are NaN values

[boxboy]

any version of mds+ on mac os after version 7-50-1 will not display any data if any of the datapoints are nan. It did work from that version going backwards

Can you provide a sample that shows the issue. Best an expression without tree dependency.

I tried for MdsDataProvider:

 Y: [0.0 : 0.4 : 0.1 , $ROPRAND , 0.6 : 1.0 : 0.1]
 X: [0.0 : 0.4 : 0.1 ,    0.5   , 0.6 : 1.0 : 0.1]

where $ROPRAND is the MDSplus representation of NaN. It plots a line from (0., 0.) to (1., 1.) that is broken at (0.5,0.5). This is what I would expect.

So I looked a little closer and I am having this issue only with 2D data. So if the data is like:

'node': '\DTS03_TE', 'data': array([[ nan, nan, nan, nan, nan], [ nan, nan, nan, nan, nan], [19.1, 21.6, 17.9, 26.4, 15.6], [ 7.2, 8.9, 11.5, 11.8, 7.3]]), 'dim0': array([0.001, 0.011, 0.021, 0.031]), 'dim1': array([-0.10325, -0.05166, -0.00165, 0.04836, 0.10074]),

and the X,Y entries look like:

Y: data(\DTS03_TE)[1,*] X: dim_of(\DTS03_TE,1)

And I have one of those for each of the array values, instead of getting 2 traces out of 4 (2 are all NaNs) none of them plot

[zack-vii]

So you expect it to plot Y: [[$ROPRAND], [$ROPRAND], [21.6], [8.9]] against X: [-.10325,-.05166,-.00165,.04836,.10074] which would look a bit like

 _________

|_._._._._|

Hm I got it to plot that but it required manual auto scaling and showed a buggy extra point that appears if you select a marker.

Actually I was expecting it to plot:

Y: [19.1, 21.6, 17.9, 26.4, 15.6] X: [-0.10325, -0.05166, -0.00165, 0.04836, 0.10074]

And then I have more entries for each row of the data array.

I also tried to do this in jScope directly: Y: [82.9, 88.6, 92.4, 84.6, 102. , 96. , 75.9, 83.5, 72.3,71.9, 53.6, 44.5, 30.4, 23.,$ROPRAND,$ROPRAND ] X: [-0.093, -0.053, -0.013, 0.026, 0.066, 0.106, 0.146,0.186,0.22, 0.26, 0.30, 0.34, 0.39, 0.47,.5,.6]

That worked fine. But if the data are pulled from the mds+ sever via jscope they are not displayed. I'll just note that I do not have this problem with older versions only anything beyond 7-50-1. We have also confirmed that the same issue exists in linux (as well as Mac)

[zack-vii]

could you instead try:

Y: data(\DTS03_TE)[,2]
X: dim_of(\DTS03_TE,1)

there might have been a change in row-maior vs column-maior. But even then, if you refer to the row index 1 you get the second row which is purely nan.

[boxboy]

no dice there. I tried several iterations and didn't get anywhere

There is a bug that was recently introduced in 2D jScope visualization. In a couple of days I will issue a PR with the fix to that and others (missing error messages)
