I’m using values from a csv file to inform the length of a group of SDL lines. However, the output lines do not have the same length as the list (see capture, point 1). Also, if i try to divide the value before input in the sdl line length component, i get an error message saying text could not be evaluated as an expression, and all the output is null (I check many times my csv file and the cells are number format, no spaces or error message).
How can I fix this? The lines are meant to form a bar graph, so it’s important that the length of the lines represent the data.
I think because there is a comma instead of a dot, GH transforms your “numbers” into points X,Y,Z (with Z=0) then transforms that back into numbers by taking the distance from the point to the origin.
thank you, I can explain better what I did to know how that works: In the center I have located points that represent a map (the position of each city). I then drew a nurb from it to a matching point on an ellipse so I can display data more efficiently. The start of the SDL line is the point on the ellipse, and the D vector was generated by offsetting the ellipse (a bit lo-fi I know!). The problem is the original points and points on the ellipse were sorted using the angle from unit y ref vector (so going around the clock), but the data I want to display does not have an angle (it’s straight from the csv file).
I hope I could explain this clearly, so how to make sure each city displays its own value?
Thank you so much, it worked! I get this problem a lot because in french we generally use commas instead of dots. So all the data I extracted from the government is written in commas.
It’s much easier for us to understand and to help if you post the files as well. Thanks.
3. Attach minimal versions of all the relevant files
If you have a gh file you have a question about, attach it to the post. Do not expect that people will recreate a file based on a screen-shot because that’s a lot of pointless work. It’s also a good idea to remove everything non-essential from a gh file. You can use the Internalise Data menu option to cut everything to the left of a parameter:
Have a look at this file, I tidied up a lot of useless stuff, and added a custom script to reorder all the wires while removing intersections. Though there is still the overlapping text problem…
wow thank you so much! It seems more clear now. However, I can’t load the excel import function in my version of the app, thus I get this when opening the file (see capture). Is there a way to open it with file path and read file as it was before? :))
thanks, i put the downloaded file in the folder. Now I get this message. I don’t see a new toolbar so I don’t know if the tt toolbar was installed successfully.
Thank you very much for you patience, it worked! So much better than what I had! I’ll get familiar with the new script, hope it’s ok if I get back to you if I have any questions I had made my script to be able to input another excel file and still get the same result, I guess this organization was kept. Thank you again!
(and sorry, my scribbles are partly in french)
