This is a simple library for plotting Radar Charts (or Spider Web Charts) in iOS.
Examples (Using random values):
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.
Just add RPRadarChart.h and RPRadarChart.m to your project. You can plot something with this few lines:
You can use simple data source protocol to show values on chart such as:
// get number of spokes in radar chart
- (NSInteger)numberOfSopkesInRadarChart:(RPRadarChart*)chart;
// get number of datas
- (NSInteger)numberOfDatasInRadarChart:(RPRadarChart*)chart;
// get max value for this radar chart
- (float)maximumValueInRadarChart:(RPRadarChart*)chart;
// get title for each spoke
- (NSString*)radarChart:(RPRadarChart*)chart titleForSpoke:(NSInteger)atIndex;
// get data value for a specefic data item for a spoke
- (float)radarChart:(RPRadarChart*)chart valueForData:(NSInteger)dataIndex forSpoke:(NSInteger)spokeIndex;
// get color legend for a specefic data
- (UIColor*)radarChart:(RPRadarChart*)chart colorForData:(NSInteger)atIndex;
