Hey, your library is really interesting.

The only problem I found was the README.md, which needs a better Installation Section. I created this iOS Open source Readme Template so you can take a look on how to easily make the Installation Section better. If you want, I can help you to organize the lib.

What are your thoughts? 😄

Hello! I found two issues.

1. function spec of protocol TKRadarChartDataSource, TKRadarChartDelegate in README.md is different from real function spec.
2. I feel lindWidth is typing error of lineWidth. So I replaced all lind to line. Thank you for your great library :)

I expect the chart to fill the entire space within the white border, and that it's centered?

Code:

import Reusable
import TKRadarChart
import UIKit

final class ReportSpiderChart: UITableViewCell, Reusable, NibLoadable {
  let labels = ["ARTISTS", "TRACKS", "ALBUMS"]

  @IBOutlet private var chartView: TKRadarChart!
  private var data: ReportData?

  override func awakeFromNib() {
    super.awakeFromNib()
    chartView.configuration.borderWidth = 1
    chartView.dataSource = self
    chartView.delegate = self
    chartView.layer.borderWidth = 1
    chartView.layer.borderColor = UIColor.white.cgColor
  }

  func configure(data: ReportData) {
    self.data = data
    chartView.configuration.maxValue = CGFloat(max(data.artists, data.albums, data.tracks, data.previousArtists, data.previousAlbums, data.previousTracks))
    chartView.reloadData()
  }
}

extension ReportSpiderChart: TKRadarChartDataSource {
  func numberOfStepForRadarChart(_ radarChart: TKRadarChart) -> Int {
    return 3
  }

  func numberOfRowForRadarChart(_ radarChart: TKRadarChart) -> Int {
    return 3
  }

  func numberOfSectionForRadarChart(_ radarChart: TKRadarChart) -> Int {
    return 2
  }

  func titleOfRowForRadarChart(_ radarChart: TKRadarChart, row: Int) -> String {
    return labels[row]
  }

  func valueOfSectionForRadarChart(withRow row: Int, section: Int) -> CGFloat {
    guard let data = data else {
      return 0
    }

    if row == 0 {
      return CGFloat(section == 0 ? data.artists : data.previousArtists)
    }

    if row == 1 {
      return CGFloat(section == 0 ? data.albums : data.previousAlbums)
    }

    if row == 2 {
      return CGFloat(section == 0 ? data.tracks : data.previousTracks)
    }

    return 0
  }
}

extension ReportSpiderChart: TKRadarChartDelegate {
  func colorOfLineForRadarChart(_ radarChart: TKRadarChart) -> UIColor {
    return .reportDivider
  }

  func colorOfFillStepForRadarChart(_ radarChart: TKRadarChart, step: Int) -> UIColor {
    return .black
  }

  func colorOfSectionFillForRadarChart(_ radarChart: TKRadarChart, section: Int) -> UIColor {
    return section == 0 ? UIColor.reportRed.withAlphaComponent(0.75) : UIColor.reportChartInactive.withAlphaComponent(0.75)
  }

  func fontOfTitleForRadarChart(_ radarChart: TKRadarChart) -> UIFont {
    return .systemFont(ofSize: 11, weight: .semibold)
  }

  func colorOfTitleForRadarChart(_ radarChart: TKRadarChart) -> UIColor {
    return .reportGrayText
  }
}

Hello,

I use your spider chart, it works perfectly well, except I want to custom just a little more the legend of my chart. change the color, the number of line and the font.

If is it possible, How can I do you it ?
