I have some trouble with an app I’m making, I receive data from a chip connected to 3 sensors then I save that data into a csv file (one csv file per day). It correctly saves the data for all the duration (albeit sometimes there is inexplicably some loss of a few seconds). But somehow when I display it in my graphs tab, either it shows correctly with no problems or, like this time, even though there is data at the recorded time, it displays it like there is none or shows the wrong values at the wrong time or it stays constant despite having increased the values…
