Hi,

Once you have your grid (mesh) object(s) inside SGeMS you can put the same variable range limits for each of them. Go to "Preferences" tab (objects panel) and than choose a object ("Preferences for:" group). Once it's chosen in the dropdown you can go to group "Properties" and than put the limits manually. If you make sure the limits are the same for all objects that single colorbar will be equivalent for all that you'll be seing.

So, easy steps:

1) Input your mesh objects (let's say A,B and C).

2) Go to "Preferences"  tab (object panel) and choose object A in dropdown.

3) Go to "Properties" group and manually put whatever minimum and maximum you want (let's say 0 and 10).

4) Repeat steps 2) and 3) for objects B and C (always with the same minimum and maximum, ex: 0 and 10).

5) In the dropdown select "". Go to "Colorbar" group and check the Checkbox for colorbar. In the dropdown of the same group choose either object A, B or C (because all of them have now the same variable range limits).

And that's it.

Hi Pedro,

thanks for answering. I already tried before doing what you told me cause it seems the more logical thing. Anyway after I change manually the range of one interpolation and go through the others, it didn´t save the previous range. I will try to explain you what I did step by step cause I believe I'm missing something on my way  since I started to use SGeMS now :)

So, I have a lot of single objects, point set data files ( let#s call them t1, t2, t3). They contain the same points (x,y,z) but different temperature T cause they refer to different instant t1, t2, t3. Then I have one object, my grid called Tank. At the end this object is a group, cause it contains all the kriging interpolation done from the single point set data into the tank. Properties of tank are therefore kriging_t1, kriging_t2, kriging_t3.

Then, in the "object panel" I select "Tank" and the properties that I want to change, for example kriging_t1. Then  in the "preference panel" I select "preference for" : TANK.  At this point it appears the scroll window properties where is already selected the sub-object I'm rendering, that is to say "kriging_t1" and there I change manually the range, let'S say 12 min - 23 max.

Then again for all the properties "kriging_ti" in the tank.

But then if I insert again in the scroll window of the properties the one previously modified... again with the old own range. :(

Where is the mistake? I didn´T see any button to save it. Should I consider in some way also the starting file (each point data set) or just the group TANK and its properties (kriging interpolation)? Could it depend on the fact that if I set the range 12 - 23 is not valid far all the interpolation? because for instance my tank at the beginning is colder and there is no point with values up to 20.

Sorry for the long answer But I want to describe you exactly what I did.

Hi,

I just press "enter" after changing each value. Other than that the procedure you've described is correct as far as I can say.

I'm using v2.5b "Build Sep 13 2011" version of SGeMS (topmenu->help->version) and it works for me. Maybe something is wrong in newer versions (SGeMS is still beta I think).

Anyway if the problem persists the only solution I can give you is to change to a different geostatistics free software (http://sourceforge.net/projects/geoms2/). GEOMS2 is also beta but it's functional. We're still trying to solve some issues but it should work fine for what you are trying to do.

If you do use it just import the data into GEOMS2 (you can export data from SGeMS in ASCII format and GEOMS2 will read it fine, or just import the originals). For each variable object you press the right mouse button and a context menu opens. Just choose object specifics, change the range for whatever you want, check the colorbar checkbox and press apply button.

You can see some slideshow small tutorials in the "Files" tab of GEOMS2 sourceforge website (example: http://sourceforge.net/projects/geoms2/files/GEOMS2_student_introduction_variograms.pdf/download) or see it's showcase to see if the plots are good enough for what you're trying to achieve (https://www.researchgate.net/publication/270893586_GEOMS2_feature_showcase_%282014%29).

Sorry for the extreme solution. It's just that I really don't know what else to suggest (SGeMS should be working). As for any doubts (or suggestions) you may have about GEOMS2 just ask away, I'm quite experienced in it.

Pedro I solved the problem just installing again the program.

Sorry Alessandro, I think that I don´t get what you mean. If I use time as Z values... Then how should I interpolate in 3D(sensors are irregularly located in a huge volume)?? I need Kriging interpolation in a volume, not in a plane. Ideally I would need a 4D interpolation (3D space and Time), but since this seems no possible I just want to render the volume in different time shots. I don´t know if it makes sense to add a fifth property to the initial point set files... (x, y, z, Temp + TIME)... It doesn'T seem useful. Am I misunderstanding your answer?

Btw thanks for the availability :)
