Hello! I need a little help figuring out how to specify specific rows to pull data from.

So basically what I'm trying to do is make a very simple text box that draws from a specific row in the graph, and then pastes the value into the field, then also takes the size data from the row next to it and applies it to the same field.

I've figured out how to get the text to paste and how to change the size, but right now the only way I know how to call for rows is through this random command.

on click do  
   field.value: random[grid.value].value 
end

I mostly just need to know how to call on specific rows though since I haven't been able to figure it out. I should be able to figure out the rest from there.

Let's say I have a grid widget like this:

The .value attribute of a grid widget is a table value.

Tables can be indexed by a string (a column name) to retrieve a column as a list, or by a number (a row number) to retrieve a row as a dictionary:

somegrid.value[1]
# {"fruit":"cherry","price":0.35,"amount":15}
somegrid.value.price
# (1,0.35,0.75,2.99,0.92)

Thus, if you want a specific cell, you can index by row and then column, or column and then row, whichever way you find convenient:

somegrid.value[1].price  # 0.35
somegrid.value.price[1]  # 0.35

Any questions?

Ok actually I ran into a weird hiccup. I'm able to call on specific cells for text just fine, but when it comes to the size I'm just not able to get it to read properly. When I try to specify a cell under size, it glitches out the size of the field and makes it disappear. (code im trying below just as example to make sure im not messing up something small lol)

on click do    
   n:random[0,1,2]    
   field.value: grid.value.words[n]    
   field.size: grid.value.size[n] 
end

Weirdly, it "works" when I don't specify a cell, but it takes the first numbers of the first two cells in the column rather than the numbers from one cell.

on click do    
n:random[0,1,2]    
field.value: 
grid.value.words[n]    
field.size: grid.value.size 
end

I tried to put the size in a different grid, but I ran into the same issue.

I suspect that what's happening is you've placed e.g. the string "50,20" into a cell rather than a pair of numbers.

There are several ways of converting a string of comma-separated numbers into a proper list. For example,

"%i,%i" parse "50,20"
0 + "," split "50,20"
eval["50,20"].value     # (this is opening a walnut with a sledgehammer)

Alternatively, if you want to store structured data within a grid cell, you can specify a column's format as "j" (JSON data) or "J" (LOVE data, a superset of JSON) and then enter your pairs like so in CSV mode:

or like so in JSON mode:

It works! Thank you!
