Layer symbology is not rendered as expected

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.
