You just need to keep track of which samples in the buffer are valid and > avoid plotting invalid samples. > Hello everyone, I stumbled across this old thread while trying to solve the problem of plotting a time series with missing/invalid data with pyqtgraph. My current solution involves invalid data indicators and creation of a new CurveItem for each bit of consecutive valid data, but the implementation is rather complex. @Luke Is there a way within pyqtgraph to plot one single CurveItem with missing data (e.g. np.nan values) and have the curve _not_ connect the two valid points, like described by Frederico? -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
