RP Radar Chart

This is a simple library for plotting Radar Charts (or Spider Web Charts) in iOS.

Examples (Using random values):

WARNING

This library is under development, actually is part of an App I'm developing at work, so don't expect it to be finished. I know the code is messy, sorry about that (I'll try to beautify it in the future). Anyway, even if isn't finished you already can:

• Plot one or more set of floats.
• Set a different color for each set.
• Customize how is the chart displayed: - Line width - Dots radius - Show or not values. - Show or not guide lines. - Show or not guide numbers. - Fill or not the drawed area.

Planned features:

• Addjust values positions if needed.
• Add a Legend for each data set.
• Animate a transitions from one data set to another.

Use

Just add RPRadarChart.h and RPRadarChart.m to your project. You can plot something with this few lines:

RPRadarChart *rc = [[RPRadarChart alloc] initWithFrame:CGRectMake(0, 100, 320, 320)];
rc.values = [NSDictionary dictionaryWithObjectsAndKeys:
                   [NSNumber numberWithFloat:10.0f],@"A",
                   [NSNumber numberWithFloat:20.0f],@"B",
                   [NSNumber numberWithFloat:30.0f],@"C",
                   [NSNumber numberWithFloat:40.0f],@"D",
                   [NSNumber numberWithFloat:50.0f],@"E",
                   [NSNumber numberWithFloat:60.0f],@"F",
                   [NSNumber numberWithFloat:70.0f],@"F",
                   [NSNumber numberWithFloat:80.0f],@"G",
                   nil]];
[self.view addSubview:rc];
