Wrong linestyle showing for plots in 2016 waveform charts.

CAR# 600682

[altenbach]

Under certain conditions, a cursor locked to an xy plot goes haywire.

Details

As hinted in the discusssion of the bug right above, there is an omission for the "Map coordinates to xy"  method. It does not say what the boolean returns. (The method for the other direction is better described)

Map XY To Coordinates Method

Mentions that it "returns true" (Good!), but the boolean output is not listed in the parameter table (Bad!).

(It is listed under "data type", but I don't even know what the means here....Why does it even need a data type? Since it is always true, it carries no useful information)

Map Coordinates To XY Method

Does not mention the boolean output at all (except as the "data type"), even though it is there. (Bad!&Bad!)

Hmmmm.... Feel free to discuss in the linked thread.

The error seems to be only in the "Constraint Nonlinear Curve Fit" , details & work around here

> CAR 590370 has been filed to track this issue. This will be fixed in next release of LabVIEW.

Many years ago, it was achnowledged that the output of reshape array is inconsistent if one of the dimensions is zero. Behavior is still present in LV2016. I wonder if there is a CAR. 

[altenbach]

Under certain conditions, feedback nodes fail to work with matrix data, breaking perfectly legal code, either at edit time or on first run. (details).

Continued in the September 2016 bug thread.

This thread is now closed.
