I'd like to see a timeline of events from a database in a "timeline chart", that should look like this:
I've made me a small c# program that paints this onto a Bitmap, but that isn't the way to go.
I have input data that has 3 fields:
StartX EndX Y 2596 15008 1 5438 6783 2 5450 5453 4 5456 5459 4 5462 5466 4 5470 5474 4 5477 5657 5 5662 5665 4 5668 5671 4
As the picture shows, for each line I'd like to have a line from
EndX with a Y value of
Stacked bar chart almost solves my problem, but I don't want to have a new line on the chart for every row, I have thousands of rows and I'd like to have X axis as the time axis, and view which events (Y is the type of the event) happened simultaneously. The image (see above) I've generated with a simple C# program shows that the event SYSTEM was active all the time, and the events TECH and BREAK were almost exclusive, but had some overlaps.
I'd like to at least know the correct direction which I should take; I'm lost in the multitude of Excel chart types.
