Parameters ---------- booster : Booster or XGBModel instance, or dict taken by Booster.get_fscore() ax : matplotlib Axes Target axes instance. If None, new figure and axes will be created. grid : Turn the axes grids on or off. Default is True (On). importance_type : How the importance is calculated: either "weight", "gain", or "cover" * "weight" is the number of times a feature appears in a tree * "gain" is the average gain of splits which use the feature * "cover" is the average coverage of splits which use the feature where coverage is defined as the number of samples affected by the split max_num_features : Maximum number of top features displayed on plot. If None, all features will be displayed. height : Bar height, passed to ax.barh() xlim : Tuple passed to axes.xlim() ylim : Tuple passed to axes.ylim() title : Axes title. To disable, pass None. xlabel : X axis title label. To disable, pass None. ylabel : Y axis title label. To disable, pass None. fmap : The name of feature map file. show_values : Show values on plot. To disable, pass False. values_format : Format string for values. "v" will be replaced by the value of the feature importance. e.g. Pass "{v:.2f}" in order to limit the number of digits after the decimal point to two, for each value printed on the graph. kwargs : Other keywords passed to ax.barh() Returns ------- ax : matplotlib Axes rNz.You must install matplotlib to plot importance)rrz/tree must be Booster, XGBModel or dict instancez_Booster.get_score() results in empty.
