To visualize temporal data (C2) in LineUp, we accumulate the temporal columns that belong together and show them in a single one-dimensional heatmap (see Figure ). For example, all values of the acquisition function for each cycle are visualized in one heatmap that changes colors corresponding to the timesteps along the x-axis [1] . This way, the progression over time is visualized in a compact way and users can investigate iterative data (T2).
