Is there some sample code or a tutorial out there about h开发者_运维问答ow to draw a line chart using the Core Plot framework? I can't find anything using Google.
I've created a Core Plot "Hello World" with an x^2 graph here: http://recycled-parts.blogspot.com/2011/08/coreplot-hello-world.html
Hope this helps!
If you have downloaded the framework, go to the examples
directory within your checked-out version. There are several examples there, including CPTestApp-iPhone (which demonstrates line, bar, and pie charts), CPTestApp-iPad (same, but for the iPad), StockPlot (which downloads stock charts and plots the line graphs for them), and AAPLot (which grabs Apple's stock price and plots it using an open-high-low-close chart).
These examples are updated as the API changes, so they can be considered reliable sources to work from.
