Hello All,

I've been using Tecplot 360 2012 because of a few features still missing from the newer versions but it is starting to feel its age especially concenring graphics drivers. I recently tried 2022r1 and noticed that one cannot plot an X vs. Y plot for all zones unless they are linear. The 2012 version didn't care. Does anyone know why this has been restricted with the newer versions (I see that even the 2018 version has issues)? I have 2D/3D zones and all I want is to plot a variable for all zones (hundredst of zones) as symbols. I guess I could create a macro but why the restriction in the first place.

Might be a 'feature' to add to the next Tecplot release.

Thanks,

John

John,

We limited the GUI to "all linear zones" because we found that people were accidentally creating line plots of their very large volume zones - which forces loading of more data than is required, causing performance and RAM consumption issues.

For your purpose of showing symbols only - are you able to do this in the 2D Cartesian plot type? It seems that you should be able to - but you may also need to adjust the Axes to be Independent (which is the default in XY, but 2D plots default to Dependent axis scaling).

I hope this helps.

Thanks for the reply.

I could do what you say, but I have a feeling that going to 2D mode might break something else in the future for which an X-Y plot would be approriate, i.e., muitple axis and variables. Otherwise I'll have to do multiple frames with transparent backgrounds to overlay X-Y plot with 2D plot and even then I don't think you can frame link across 2D and X-Y for axis size to match everything up. Is there anyway to re-activate the option for those of us who are careful not to select the option 'accidentally'? Could be something to put in the .ini file.

Thanks,

John

John,

In the near term you could add to your tecplot.mcr file the following code:

Code:
$!MacroFunction
  Name = "Create linemaps for all zones"
  ShowInMacroPanel = True
  $!DeleteLineMaps
  $!Loop |NumZones|
    $!CreateLineMap 
    $!LineMap [|Loop|] Name = '&ZN&'
    $!LineMap [|Loop|] Assign{XAxisVar = 1}
    $!LineMap [|Loop|] Assign{YAxisVar = 2}
    $!LineMap [|Loop|] Assign{Zone = |Loop|}
  $!EndLoop
$!EndMacroFunction
This will add an entry to the Quick Macro Panel, which you can simply double-click to create a set of linemaps for all zones.

Regards,
Scott
