Chartjs barchart group dataset by label

I'm trying to create a grouped barchart graph but looks like there is no built in solution for it on chartjs, has anybody such experience before with grouping dataset by label, please check screenshot
chart trying to achieve
Idea is to have 4 different datasets with at least 4 data each and show in graph grouped.
Trying to achieve this with latest chartjs but I'm open to change it if there's easy way to do it with different library.
Thanks in advance

HighCharts for stock prediction data

I am using HighChart library for creating charts in my web application in ASP .Net.
First i use this Candlestick chart for showing the company's stock on chart.
Now i want to create chart for forecast data (RSI CFM Typical Price Moving Average) values on chart.
I see the following picture somewhere but i don't have its example or demo.
Is there any working example for that?
It looks like scenario where indicator are calculated as additonal series. Check the plugins registry, where some of them are implemented.

Simplifying a line before rendering on chart in d3

I am trying to plot data collected live from bee hives. We plan to collect data every 5 minutes, so in a year there will be on the order of 100,000 data points. I want to set up a chart to plot the data, and have new data enter the chart everytime the database changes (using Meteor).
I have a simple mockup at datacomb.meteor.com These charts were made using dc.js, a d3 wrapper.
Is there a way to use the topojson.simplify (http://bost.ocks.org/mike/simplify/) functionality to pre-process the lines and reduce the number of points rendered? Has a more general simplification method been integrated into d3?
Have you looked at Simplify.js? It does exactly this.
