I am developing an ArcGIS Pro python tool. I am using "JSONToFeatures_conversiontool" to convert Esri GeoJson to feature class.
After adding a layer to map I am changing the symbology.
1. on the output layer (Point Layer ) -
scriptPath = sys.argv[0]
toolSharePath = os.path.dirname(os.path.dirname(scriptPath))
dataPath = os.path.join(toolSharePath, 'iGeolise')
pointLyrPath = os.path.join(dataPath, 'updateFilterSymbol.lyrx')
params = arcpy.GetParameterInfo() desc = arcpy.Describe(Output_layer)
params[symbology_index].symbology = pointLyrPath
2. Using custom renderer (Polyline layer)-
layerName = (arcpy.Describe(Output_layer)).baseName
p = arcpy.mp.ArcGISProject('CURRENT') m = p.listMaps('Map')[0] m.addDataFromPath(Output_layer)
lyr = m.listLayers(layerName)
for l in lyr: if l.name == layerName :
classBreakValues = [5.0,15.0,30.0,60.0,120.0,300.0,14400]
classBreakLowerValues = [0, 5, 15, 30, 60, 120, 300]
classBreakLabels = ["0-5 min", "5-15 min", "15-30 min", "30-60 min", "1-2 hrs","2-5 hrs",">5 hrs"]
sym = l.symbology
if sym.renderer.type == 'SimpleRenderer':
sym.updateRenderer('GraduatedColorsRenderer')
sym.renderer.breakCount = len(classBreakValues)
sym.renderer.classificationField = 'travel_time'
sym.renderer.nomalizationType = ''
sym.renderer.colorRamp = p.listColorRamps('Yellow to Red')[0]
count = 0
for brk in sym.renderer.classBreaks:
brk.upperBound = classBreakValues[count]
brk.label = classBreakLabels[count]
count += 1
l.symbology = sym
It is working fine on large data, but when on the very small data(1 to 3 records), symbology is not rendered as its expected behavior.
I have attache the layers please refer to generate the result.
Need help to solved this.
