How to properly graph historical marketdata?

Dear MD,

so in the last days I have been curiously trying to compare a few market items over time.

Sadly there is no way to pull out a few selected items and compare their price or any available marketdata in a nice and "easy to look" at way.


Lets say I would like to compare the average price of a Rifter with the price of tritanium and a Merlin ( looking at 3 graphs at the same time, probably having 3 lines in one graph rather~).

I fail at finding a fast way of doing just that.

There is so much historic data available on both eve-marketdata and evemarketeer, aswell as current data from eve-central.

However, noone seems to be willingly design a tool that lets you enter lets say the item ID's to display some graphs for you.
The "only" thing the tool would need to to is work with a eve-marketdata api and some filters to show you a few nice comparisons.

Did I miss any neat tool that helps me do that?

- I tried vahk's approach with multicharts, but it takes too long
- I tried writing my own google spreadsheet, but I fail
- I tried googling, but I dont know what to look for

Anyone got a link for me?

Good point, I will write it at my ToDo-List.

Quite by chance, I'm building my own application for market data analysis (trading, speculation, monitoring), cause I'm kind of pissed to use different kind of applications for different concerns and I'm looking for new ways for statistical evaluation.

It's just built on the .NET framework (C#, WPF) using the MVVM pattern combined with telerik controls (see some examples in silverlight here), providing plenty of options to visualize statistic data. Indeeds it eats up a lot of resources, but imo it's the easiest way of implementation without desgning my own controls.

EVE API is quite easy to implement, as there a tons of third party implementations around. I'm using EVEAI.
My current issue is to find a reliable source to access historical data and I'dont know about any third party implementations to access those APIs such as eve-marketdata and evemarketeer. I'm not eager to implement the API access and caching.

Anyone knows about a great third party implementation for easy access for that purpose?
