I have found some question about DSC module like the picture you see ,there are two lines. ONE is white ,the other is blue.The white one has lost at some place,but the blue one was continuous.
As I know,the computer was crashed at August 25,but the data loss occurred in August 23.It's a long time.So can anybody tell me why it happened.
What is the data? What is displaying the data (graph or chart)? What does your code look like? Why did you post a 4M image to the forum?
NaN in the data will appear as gaps in plots.
Also, if you are using timestamps from different sources for different channels, you might see gaps as different time sources will most likely (99.9999999% chance) drift to one another. So depending on how often time is "synchronized", the gaps will get different lengths.
