http://stackoverflow.com – I was wondering if it was possible to have a graph with two separate Y axis. My program has 6 individual lines that are graphed on one graph. However 3 of these lines have values MUCH smaller than the other 3. Let's say that the 3 lines with the big values range from -700 to +700, and the 3 lines with the smaller values range from -2 to 2. My application requires bluetooth to receive the data to make graphs, so I tried to make an example in Excel. There is 1 line with values from -300 to 300( Pink ), and a line with values from -50 to 50( Blue ). I would like to have the graph act simil (HowTos)
