from System.Drawing import Color
from Spotfire.Dxp.Application.Visuals import *

#Add a vis parameter referencing an existing LineChart visualization
vis = vis.As[LineChart]()

#Clear all Lines & Curves for a visualization
vis.FittingModels.Clear()

#Loop through all the Lines & Curves collection
for fm in vis.FittingModels:
 #To remove a specific line or curve
 if fm.Line.DisplayName == 'Avg(Y)':
  vis.FittingModels.Remove(fm)

#Adding AddHorizontalLine
horizontal_line=vis.FittingModels.AddHorizontalLine("Avg([Y])")
horizontal_line.Line.Visible=True
labels_tooltips=horizontal_line.Line.Details
#Loop through all the labels and tooltips and enable/disable them
for lt in de:
 print lt.Name,lt.DisplayName,lt.ShowInLabel,lt.ShowInTooltip
 lt.ShowInLabel=True


#Adding AddStraightLineFit
straightfit_line=vis.FittingModels.AddStraightLineFit()
straightfit_line.Line.CustomDisplayName="My_Str_Line"
straightfit_line.Line.Color=Color.Brown


#Adding curve
c=vis.FittingModels.AddCurve("Avg(10)")
c.Curve.Visible=True
c.Curve.Color=Color.Green
