pyNomo playground
Hello all,
I have worked some time to make a web service "pyNomo playground" for running pynomo scripts. Now it is available as early beta in address:
http://46.101.125.20:8080
Check out and enjoy!

Re: 6 variables equation
One possibility to try is to fit your data to the nomographic matrix form. In my script there were 9X6=36 variables to tune (for example f1_0,f1_1,f1_2,f1_3,f1_4,f1_5, etc.). One could pick up some (clever) set from these variables and to try to fit data to tune them.

Re: 6 variables equation
Are you trying to make nomograph of some specific equation or just work a very general case? If you have a specific equation as polynomial approximation, it could be easier to use the original equation. If you could post the original equation here (or with email if you want to limit the audience)? b...

Re: 6 variables equation
Hello, I think this is tough question. Equation is possible to cast into nomographic form if it can be turned into determinant of matrix equals zero, where each row of matrix has functions of only one or two variables. In your case this could be three-grid nomograph and a determinant of matrix: [f1,...

Re: Duodecimal tickmarks?
Hello Jason,
For manual axis you can use parameters:
'text_distance_1' and 'grid_length_1'
to set text distance and tick marks length. Text size can be set with
'text_size_manual'

Thanks for the link! I had seen the slides but now also watched the talk that had very good discussion of cons and pros of nomographs.

Hello, little too many iterations with this case, but I think now it should work...

Re: Nomogram for 5 variables
Hello Markus, I think you over defined the nomograph isopleths. I think the key was to have an 'x' instead of 1 in: 'isopleth_values':[['x',0.1,1.0,'x']], Here is the nomograph code little tweaked. Some ranges need to be still adjusted. For example r1=20 is always out of range. from pynomo.nomograph...

Re: Duodecimal tickmarks?
Thanks Dave for your comments! PyNomo uses 5 levels of ticks in scales. Default settings for these are (taken from nomo_axis.py) 'text_distance_0':1.0, 'text_distance_1':1.0/4, 'text_distance_2':1.0/4, 'text_distance_3':1.0/4, 'text_distance_4':1.0/4, 'grid_length_0':3.0/4, 'grid_length_1':0.9/4, 'g...

Re: Nomogram for 5 variables
Hello drafter, sometimes one can write an equation into determinant form with grid(s) but the grids collapse and are useless. == Proposal 1 == Alternative solution to your equation is to write it as Q*l/e = r1^2/(r1^2-r2^2) and in inverse form e/(Ql) = 1-r2^2/r1^2 and split with dummy variables A,B ...

Re: Nomogram for 5 variables
Hello,
you are correct. I missed a sign in the expression
I have to say that at the moment I do not see how this equation can be presented as a nomograph. This does not mean it is not possible.

Re: Nomogram for 5 variables
Hello, here is one approach. Write your equation (with new dummy variable D) as: Q L = D (1) D = e r1^2/(r1^2-e^2+r2^2) (2) So you have easy part (1) and the difficult part (2). Equation (2) can be written as a determinant |(-D+e) -D -D*e^2| | 0 1 r2^2| = 0 | 1 0 r1^2| Depending on ranges and luck, ...
