Colour meshes according to European Standards - issue

Hi Claudia,

The difference between these maps is that the first one comes from some conditional statements - e.g. if the DF is greater than 2 set this color.. this function doesn't generate gradient colors, you have written a treshold function. While, the second map follows a gradient function, you have remapped values inside a domain of colors.

Sorry, I don't understand well what type of map do you want to reach (with gradient colors or treshold colors).
Could you clarify this for me? thanks.

Hi Antonello,

Thanks for your explaination.

Actually, I put the two images just to show the errors of the remapped one.

To be more clear, what i meant is to create a map with treshold colors like:

for the DF below 0.7 --> red

for the DF between 0.7 - 2.2 --> orange

for the DF between 2.2 - 3.6 --> yellow

for the DF between 3.6 - 5.4 --> green

for the DF up to 5.4 --> white

So in my mind the maps should have white colors next to the glazing system, then green, then yellow and so on. But as you can see from the one i have done, a part from the red colors, the others are not congruent with the real DF in the second image.  

I would like just to know what is wrong in the workflow, if the functions or the meshes ...

Thanks

Claudia

Hi Claudia,

I'm not sure, because I can't check well your workflow. But, as you said, this could be related to:
1) mesh construction by points
2) how you set the function inside evaluate GH component
It seems an issue of order the list.

Anyhow, you can test this small example that I prepared for you. it requires a MeshEdit component, you can find it on Food4Rhino.

I suggest that you use analysis mesh output instead of points.

Let me know if it works.

Hi Antonello,

Thanks a lot for your workflow!

But I have still a question/problem: in your workflow, you can choose both the low and high boundaries, and then you can also decide in how many segments you want to divide the legend. Right?

BUT how can you define also the values between the boundaries?? As said before, i want to have the following steps: 0.7 (which is the low boundary), 2.2, 3.6 and 5.4 (which is the high boundary).

Thanks again

Claudia

Hi Claudia,

I have done some tests and it is possible to create the legend that is suitable for you.

but you should modify two lines of Ladybug Ladybug code.. I think we have to write something easier to do that. Thus, I ask you if you can wait for that, I have to talk with Mostapha and Chris. Thanks

Furthermore, you could just use 'Ladybug contourMesh' to achieve a pretty visualization, but it requires some changes, too.

Hi Antonello,

Thanks a lor for your reply! This is finally what i was looking for!!! :)

Can you please tell me which changes have you done in "Ladybug contourmesh" to achieve your final visualization?

Thanks a lot again

Hi Claudia,

From what I understand that you need, you should use the recolour mesh from ladybug and customize the legend parameters.

I uploaded a file of that part of the workflow. Hope it helps.

Julia

Edit: I Forgot to put in "True" the bolean in the legend par removing the less than, you probably will want it in running.

Hi Julia,

thanks a lot for your reply.

But i think that you workflow can just change the color of the maps, right?

What i want is to assign a color for a range of values of DF .

i.e.:

for the DF below 0.7 --> red

for the DF between 0.7 - 2.2 --> orange

for the DF between 2.2 - 3.6 --> yellow

for the DF between 3.6 - 5.4 --> green

for the DF up to 5.4 --> white

I don't think i can do it with your workflow. Am i wrong? I hope so!

Thanks

Claudia
