For example, for a fixed axis, adding some interactivity so that the user can set x between 0 to 1000 for the below piece-wise function:

def fun1(x):  
if(x\<=100):  
return x  
elif(100\<x\<=200):  
return x  
elif(200\<x\<=500):  
return 50+((x-250)\*0.5)  
elif(x\>500):  
return 350+(x-500)

Is this possible in Plotly?
