Questions:
Are slope charts not too bad to make?
How can I make one?
Is there a good alternative?
Goal:
I think I want to track OEE, Machine across months and days instead of just year.
Background:
I had never heard of a slope chart before, but it looks like the thing that would make it easy to see the performance changes.
Right now, I have 60 day bar charts of the machines that are organized so you can kind of scroll through them, and sort of go back-forth till you kind of get what this slope chart would relay more succinctly.
I could see getting this done in Vison, though it would be very Java Intensive, and very far from trivial. I am not sure if JFree has an axis type for this type of cart or not.
As far as perspective goes, I don't think there is any way to make the current charting options work for this. You would need to get pretty deep into AmCharts to even know if it is possible. A very quick search yielded nothing for me.
You could build a custom module to add a chart component to make this possible, though again, very far from trivial.
I would think that a Multi-series Bar chart would be the standard way to show data like this, and that is definitely possible in Vision and Perspective.
