Serial data split for plotting

Hello, i am faceing some isues trying to plot two numeric values.

I have the following code

while (s.Status == 'open')
   C=fscanf(s);
   display(C);

End

Now on my controler i send the following value1$value2\r\n I want to extract separate the value1 and value2 after that i will plot on a graph. the data is floating type.

in my code C =1.4$0.5 , how can i split these two and use separate?

For example based on my incoming C string to have A=1.4 and B=0.5

Thanks
