What's the "easiest" way to implement some real-time trending plot on the internet?
I want to have five graphs, each graph having four colored dataset.
The four dataset will share a common time on X axis, but will have different Y axis (two Y axis on the left and two Y axis on the right)
Each graph needs to update ever 5 second (unless there's no new data).
User can show historical data from previous 0.1 to 96 hours (selectable), while trending.
