Issue about tree structure and distribution point of cells using different processed data by plot_cell_trajectory function

[sunshine1126]

Hi, thank you for this awesome tool! I noticed that the plot_cell_trajectory function using the different processed data, that is, the tree structure was shown using dp_mst generated from minSpanningTree but the distribution points of cells were displayed using data_df generated from t(monocle::reducedDimS(cds)) which was reduced dimension, which would eventually lead to inconsistent sequence and position of cells. I don't understand why? Can you help answer this question？ Thanks again！
