For basic plot types: Line, Scatter and Line+Symbol, user can change plot type in Plot Details dialog. When changing plot type, some customization on plot is lost. We tried to keep as many properties as possible.
Note: Instead of changing plot type in Plot Details dialog, user can click Line, Scatter, Line+Symbol toolbar buttons on bottom of workspace to switch plot types as well. But sometimes plot styles lost as well, e.g. line style, dropline, fill color gone.
Fixed in Origin 2023
