So we start out by crating this view, and adding it as sub-view:.
Core Plot supports a variety of chart or, plot types, such as bar and pie chart, but for this scenario, we want a simple line graph, which is done via a CPScatterPlot. To round things off, we also tell the plot to fill the area underneath it with a gradient, going from almost-transparent green to nothing. This gives the plot some depth, without hiding the other plots.

This was quite a bit setup, but our graph is now ready plot, and will ask its data source our cell for data by sending it messages from the CPPlotDataSource protocol. To the protocol, two methods need to be implemented. See the Example Graphs wiki page and the example applications for examples of some of its capabilities.
Documentation of the Core Plot API and high-level architecture can be found in the following places:. Core Plot is an open source project hosted on GitHub.

There are two code repositories under the main project:. This is where you will find the release packages, wiki pages, and issue tracker. Everyone has a their own preferred coding style, and no one way can be considered right.
Nonetheless, in a project like Core Plot, with many developers contributing, it is worthwhile defining a set of basic coding standards to prevent a mishmash of different styles which can become frustrating when navigating the code base. Core Plot includes a script to run Uncrustify on the source code to standardize the formatting.
IT, Cool Stuff, and Learning
All source code will be formatted with this tool before being committed to the Core Plot repository. Recently, Bemo started a new project that requires the use of graphs to display data.
Data visualisation, particularly graphs that have some form of interaction, are becoming an important part of many applications. But how do we decide on a library which provides the best solution for our project?

Both libraries offered the graph types we needed for development, so the deciding factor would be down to development in practice. Below is a breakdown of our findings, including a general overview of both libraries and a sample implementation of each, making it easier for you and your team to choose the best fit for your next visualisation based application. License: BSD license. One of the main attractions to CorePlot is that it is consistently maintained, despite the fact that it was created in The documentation is extensive, with a set of API documentation built with Doxygen , a wiki and clear descriptions of most of the methods and classes.
This view acts as a container for all the components that make up a graph Axis, plots, legend, annotations, etc.

Then, we create components and add them to it. It is similar to how a UITableView works. Because are we already familiar with the use of protocols to manage interactions and data like a UITableView does, this makes it simple to implement.
