I want to chart average data readings as data is being received. But I also want to show when no data was received.
So basically, each minute I send a sample of data, and that is charted, either a as a line, or a bar chart showing the average reading. But if no readings are received that minute, then I want the line or bar chart to either drop to zero or not exist at all. Once data starts coming in again, the chart should begin charting again, but it should not interpolate or try to “fill the gap” of missing data.
Any ideas how to chart data in that way?
