tool extends Chart # [Linechart] - General purpose node for Line Charts # A line chart or line plot or line graph or curve chart is a type of chart which # displays information as a series of data points called 'markers' # connected by straight line segments. # It is a basic type of chart common in many fields. It is similar to a scatter plot # except that the measurement points are ordered (typically by their x-axis value) # and joined with straight line segments. # A line chart is often used to visualize a trend in data over intervals of time – # a time series – thus the line is often drawn chronologically. # In these cases they are known as run charts. # Source: Wikipedia # --------------------- func _get_property_list(): return [ # Chart Properties { "hint": PROPERTY_HINT_NONE, "usage": PROPERTY_USAGE_DEFAULT | PROPERTY_USAGE_SCRIPT_VARIABLE, "name": "Chart_Properties/are_values_columns", "type": TYPE_BOOL }, { "hint": PROPERTY_HINT_RANGE, "hint_string": "-1,100,1", "usage": PROPERTY_USAGE_DEFAULT | PROPERTY_USAGE_SCRIPT_VARIABLE, "name": "Chart_Properties/labels_index", "type": TYPE_INT }, { "hint": PROPERTY_HINT_NONE, "usage": PROPERTY_USAGE_DEFAULT | PROPERTY_USAGE_SCRIPT_VARIABLE, "name": "Chart_Properties/show_x_values_as_labels", "type": TYPE_BOOL }, #
