2 criterias to organize data by VLookup

What I need to analyse is evolution of prices in time. For each item its done. I made the graph.

For the companies, the P.S. 2 is perfect if possible. I need to know time. But I don't know how to make excel understand the company as color, the item as dot, the X as time and Y as price.
The data doesn't need to be aggregated. As you have each dot as a new quote floating in the chat according to time and price.

I made a new one. This one is better because it have more companies for each item, more realistic: Data v3.xlsx

Glad that half of it is done!

About the 2nd graph:
When you say

it looks like you're talking about a "scatter plot" type chart, and you want to ignore model types in this graph.

I made the graph you asked, see uploaded workbook.

P.S: If it makes sense to you I'm glad; but I think this graph is even more confusing than the first graph we made. :/
