Mathematica writes an almost void graph to file

Dear Group,

I am trying to write a png-graph to a file. The graph is known in memory, I can query it.

But when I write it to a file, I get the attached graph.

The command used is

Export[bn, StiPlots[V, h], ImageSize-> 800];

where bn is the filename, StiPlots[V, h] is the graph to be written to the file.

This is all the more obscure as

  1. this command is the last one in a block of identical commands for different graphs. The problem arises only with this particular one.

  2. this block of commands rests in a loop over the parameter h. For h=0 the graph is written to the harddisk, but not for h=1.

The filename bn depends on h (not showing here).

We use Mathematica 10.3.1 for Microsoft Windows (64-bit).

Anyone here who could assist us ? Our Premier Service has expired.

Thank you for sharing your expertise

Without explicit code, there is not much to comment. It looks to me like your plot is empty or so. I see 2 empty lists…

The graph is known in memory, I can query it.

You save it as a bitmap file, or?
Does this work:

Rasterize[yourplot,"Image",RasterSize -> 800]
5

It is png.
Rasterize does not help. Same as before.
I failed to state that I can save to disk when I re-run the snippet of code manually. The failure occurs during execution of “Evaluate Notebook” from the drop-down-menu.

Try setting:

 $HistoryLength = 1

such that the memory does not grow excessively during evaluation…

Again, without explicit code, it is very hard to guess!

Not possible as I Need previously generated Output for my Analysis.

I am giving up, will run this command manually once my Notebook has run to the end.

Anyway, thanks a lot for your effort.
