Error in Ploting Different Points with Different Colours

[WilliamLin39]

Hi, 

     I'm trying to make a graph with different colours for points. The input is a 2D array with x in 1st column, y in 2nd column, and 3rd column for colours. But the code shows there is an error. What is that, and is there any improvement?

Does the plot exist at the specific moment when you try to change it's properties?

From the error message I can say: the answer to this question is "No!"…

Sure!

You need to create several plots when you want to set properties for several plots!

Right now you create only one plot - and with each iteration of the loop the graph is overwritten…
