Hi, So far my plotting needs have been sort of ignored as I got acquainted with R this week, but now that I have the basics in place for the program I wanted to write it's time for me to start learning about how to make output that better suits my needs. I think I have two sort of charts I need to concentrate on learning how to produce:
1) Probably a trivial request - a single chart that has multiple lines on it in different colors. I might have 500 to 1000 lines, all starting at 0,0 on the left and proceeding to the right where they end either above 0 or below 0. There will groups of colors depending on the group they are part of. I'd like a legend on the right or bottom that explains the colors. I should be able to add or remove lines at any time. 2) The closest example of the second would be a multi-study chart sort of like is typical in a lot of stock charting programs. Here's (I hope) a simple example: http://stockcharts.com/h-sc/ui?s=BAC I'm not going to plot stock price data, or don't plan to anyway, but the thing I need in a chart is this multi-study aspect - essentially 3 charts in the example, all sitting on top of each other, with their own axises. It might not be immediately clear that the link shows an upper chart with two parts - the price data (with volume and moving averages) and the uppoer portion that has an RSI indicator - in separate studies on the same chart, with a second chart immediately below it that has the MACD indicator. With all the great plots I've seen so far I suspect these requests are pretty easy for the experts so I'm hoping for a few good ideas and maybe a few examples somewhere to help me get started will be all I need. Keep in mind I've not used any command other than plot() and par() so far. I *very* new to this. I started looking at ggplot2 last night. I haven't looked at Lattice. Any recommendations on where I should look next are warmly appreciated.
