Hi, I am new to plotly and R and learning, I am struggling with plotting multiple datasets in one view  
I have dataframe 1 with first column Wavelength[1:2048,1] and the next 400 columns measurement data [1:2048,2:401]  
and dataframe 2 also first column wavelength and next columns data.

the first dataset I plot with:

AEDDataMelt \<- melt(AEDPlotData, id=“Wavelength”)  
plot\_ly(AEDDataMelt, x= ~Wavelength, y= ~value) %\>%  
add\_lines(color = ~ordered(variable))

how to add lines in the same view from another dataset without haven to merge and melt ?

thanks for the help
