Line Plot from Scientific Research

Traces showing the variation in cytoplasmic calcium (y axis) concentration in example cells (line) across time (x axis), following ATP stimulation. Variation in calcium concentration shown as difference in fluorescence. Cells are six groups using k-means clustering on features extracted from the traces: large peaks; inactive cells; cells with large early transients; cells with a small peak; cells with a step; and finally, cells with a delayed response.
