search for: scattergraphs

Hi I have two datasets, A and B, consisting of two columns of numbers representing x and y coordinates. They have 10 and 6 rows respectively. I want to plot two scattergraphs, one above the other. The lower graph to contain A (10 points) and the upper graph to contain B (six points). The x-axes of the two graphs must line up. I then want to draw straight lines that connect points of B to a particular point (or points) of A. How do I do this? -- Robin Hankin Unce...

Hi everybody, I really appeciate the help you have given me. I am getting around R comfortably now and am able to import research project data, do mathematical analysis of the data and produce graphs. My PhD project is going really well in its early days, already collecting data and proposal completed soon! There is one question I have though. I can see that worksheets and history can be saved,

Dear all, I have 3 datasets all of which share the same longitude and latitude values, which I'm looking to plot onto a scattergraph. The third dataset has values which can only be either '1' or '2'. So to incorporate all three datasets onto two axes, I'm wondering if I can plot dataset1 and dataset2 as normal, but then use colour to determine whether these points are
