Garbage on the Intensity Graph

[Artem.SPb]

I work with Intensity Graph
I write the data (via terminal) and, if necessary, programmatically change the Z scale (adjusting the brightness and contrast).
Despite the fact that the data does not change, sometimes garbage appears on the graph, something like this.

I have attached a file (LV12 + 16) in which such a graph is saved. I display data from it on another graph, and it looks correct.
How to fix this bug? It occurs when I simply set the properties of ZScale.minimum / ZScale.max

I guess, you should use the property node!?

Simply use the two property nodes as shown above. Than your scaling as adapted to your measured values.

Of course, I use two properties. But I do not need the autoscale. Scale values ​​must be independent of data values.
