サマリー

The Guide class contains properties for configuring chart guides.

説明

When creating this object, optional arguments for the class constructor must be specified using the argument name; they cannot be specified by argument position. See the Code sample section for an example of how to specify arguments using keywords.

Guide (guideType, {name}, {label}, {valueFrom}, {valueTo}, {valueFromField}, {valueFromFieldAggregationType}, {polyline}, {lineColor}, {lineWidth}, {lineDashStyle}, {fillColor})

パラメーター	説明	データ タイプ
guideType	Specifies the type of guide that will be created. line—A line guide will be created. Use this value in conjunction with the valueFrom argument. range—A range guide will be created. Use this value in conjunction with the valueFrom and valueTo arguments. polyline—A polyline guide will be created. Use this value in conjunction with the polyline argument.	String
name	The unique name for the guide that will appear in the Chart Properties pane.	String
label	The guide label that will be displayed in the chart.	String
valueFrom	The location of the guide when creating a line guide, or the start location of the range when creating a range guide. Use a double value for numeric axes and a datetime object for temporal axes.	Object
valueTo	The end location of the range when creating a range guide. Use a double value for numeric axes and a datetime object for temporal axes.	Object
valueFromField	The field name whose values will be used to calculate the location of a data-driven guide. Use this argument in conjunction with the valueFromFieldAggregationType argument.	String
valueFromFieldAggregationType	Specifies the statistical calculation that will be used to determine the location of a data-driven guide. Use this argument in conjunction with the valueFromField argument. MEAN—The mean of all values will be calculated and applied. MEDIAN—The median of all values will be identified and applied. MIN—The minimum value will be identified and applied. MAX—The maximum value will be identified and applied.	String
polyline [polyline,...]	A list of coordinates that will be used when creating a polyline guide. Coordinates should be in row-major order. Create a polyline guide. # Coordinates will be: (0, 2), (10, 12), (20, 15) coordinates = [0, 2, 10, 12, 20, 15] guide = arcpy.charts.Guide(guideType="polyline", polyline=coordinates)	List
lineColor	The color of a line guide in hexadecimal format.	String
lineWidth	The width of a line guide.	Double
lineDashStyle	Specifies the dash style that will be used for a line guide. solid—A solid style will be used. dot—A dot style will be used. dash—A dash style will be used. dashDot—A dash-dot style will be used. longDash—A long-dash style will be used. longDashDot—A long-dash-dot style will be used.	String
fillColor	The fill color of a range guide in hexadecimal format.	String

コードのサンプル

Guide example 1

Add two guides to a scatter plot showing the average value for each axis.

import arcpy

chart = arcpy.charts.Scatter(x="voter_turnout", y="per_capita_income", dataSource="VoterTurnout2020")

# Create and configure guides
guideX = arcpy.charts.Guide(guideType="line", valueFrom=65.6, label="Avg. Voter Turnout")
guideY = arcpy.charts.Guide(guideType="line", valueFrom=26823.8, label="Avg. Per Capita Income")

# Add guides to appropriate axis
chart.xAxis.addGuide(guideX)
chart.yAxis.addGuide(guideY)

chart.exportToSVG("chart_with_guides.svg")

Guide example 2

Add a data-driven guide to a bar chart to show the average value for the y-axis.

import arcpy

lyr = arcpy.mp.ArcGISProject("current").listMaps()[0].listLayers()[0]
chart = arcpy.charts.Bar(x="State", y="TotalPop", aggregation="MEAN")

# Create data-driven guide
guide = arcpy.charts.Guide("line", valueFromField="TotalPop", valueFromFieldAggregationType="MEAN")

# Add guide to y-axis
chart.yAxis.addGuide(guide)

chart.addToLayer(lyr)
