Using the History component
The History component makes it possible to plot a value in a chart that changes in real time, while preserving its historical data. If that sounds confusing, think about the stock market charts that track the fluctuation of a stock price. At the start of the day, the line in such a chart is short, while at the end of the day the complete trend of the stock price for that day is shown. This recipe will show you how to set up this kind of functionality in your dashboard.
