List Groupings


#1

Hi im new to Dynamo
But having been creating some new graphs for small items but still a learner
I’m having a Dynamo Issue and a little stuck at a point.
First Example below: Output Successful
Which is more or less the result I require. Giving me the totals of each item
But my input list has the items all in 1 list. Which is then easy to count per Instance as shown.

But My First List I need to Split into parts and then count each Instance and give me a total


Any help will be appreciated I’ve been stuck here for 2 days.

In what way do you want to split the list?
If you want to count the amount of instances you can simply use the count node.


#3

Can you elaborate on what the exact issue is?
This is a simple way of counting items or grouping by function.

So… in the picture above I have a list of instances. that i’m counting and listing one item and how many time that item occurs.
No I want to breakup this list as seen in this picture
Split%20List
but still get same result per group so my end result should be

Alarm Panel =1
42"Display = 1
Single RJ45 Data Outlet = 2

Alarm Panel = 1
Intercom = 1
Wifi Point = 1
55"Display = 1
Single RJ45 Data Outlet = 4
Dual RJ45 Data Outlet = 1
Single RJ45 Data Outlet - Celing Void = 1
