if you want to hide label above bar

barChart.setOptions([.isHiddenLabelAboveBar(true)])

if you want to hide labels and lines

barChart.setOptions([.isHiddenExceptBars(true)])

if you want to add some gradient to your bars

barChart.setOptions([.isGradientBar(true)])

// Instead of assignmentOfColor 
barChart.assignmentOfGradient = [0.0..<0.25: [#colorLiteral(red: 0.1294117719, green: 0.2156862766, blue: 0.06666667014, alpha: 1),#colorLiteral(red: 0.1960784346, green: 0.3411764801, blue: 0.1019607857, alpha: 1)], 0.25..<0.50: [#colorLiteral(red: 0.1960784346, green: 0.3411764801, blue: 0.1019607857, alpha: 1),#colorLiteral(red: 0.2745098174, green: 0.4862745106, blue: 0.1411764771, alpha: 1)], 0.50..<0.75:[#colorLiteral(red: 0.2745098174, green: 0.4862745106, blue: 0.1411764771, alpha: 1),#colorLiteral(red: 0.3411764801, green: 0.6235294342, blue: 0.1686274558, alpha: 1)], 0.75..<1.0: [#colorLiteral(red: 0.3411764801, green: 0.6235294342, blue: 0.1686274558, alpha: 1),#colorLiteral(red: 0.4666666687, green: 0.7647058964, blue: 0.2666666806, alpha: 1)]]

Installation

CocoaPods

MSBBarChart is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'MSBBarChart'

Carthage

Carthage is a decentralized dependency manager for Cocoa application.

$ brew update
$ brew install carthage

To integrate MSBBarChart into your Xcode project using Carthage, specify it in your Cartfile:

github "misyobun/MSBBarChart"

Then, run the following command to build the MetaRod framework:

$ carthage update --platform iOS

You will then have to drag MSBBarChart.framework yourself into your project from the Carthage/Build folder.

  • Scrolling clips content

    Scrolling clips content

    With a large dataset, the chart enables scrolling but then clips the last bar when it settles. Also the y axis interval lines don't cover the entire width of the view when scrolling is enabled.

    image

    ^ pulling the view reveals the last bar 31 ^

    image

    ^ letting go settles the view and clips bar 30 and 31 ^

    image

    ^ bar 1 and 13 are visible but the axis and interval lines don't extend that far ^

  • crash when chart data is empty

    crash when chart data is empty

    When there is no data passed to the chart it attempts to draw the view but CALayer crashes due to NaN in the yPosition

    In version 1.1.1 this didn't crash. In version 1.1.2 it crashes.

    Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [30.7857 nan]. Layer: <CALayer:0x281b12640; position = CGPoint (30.7857 246); bounds = CGRect (0 0; 45.5714 0); allowsGroupOpacity = YES; anchorPoint = CGPoint (0.5 1); backgroundColor = <CGColor 0x283fba520> [<CGColorSpace 0x283fa4420> (kCGColorSpaceICCBased; kCGColorSpaceModelRGB; sRGB IEC61966-2.1; extended range)] ( 0.152941 0.658824 0.909804 1 ); animations = [bounds=<CABasicAnimation: 0x281b13d80>]>'

  • Incorrect Bar Height or Incorrect Interval Label

    Incorrect Bar Height or Incorrect Interval Label

    Sometimes the bars are drawn at incorrect heights in relation to the interval lines when I set yAxisNumberOfInterval option.

    If I don't set that option, then the charts draw correctly.

    This one, I set .yAxisNumberOfInterval(4) image

    This one, I set .yAxisNumberOfInterval(4) image

  • Make it be scrollable by setting the minimum width of the bar

    Make it be scrollable by setting the minimum width of the bar

    Overview

    Since the bar width was determined based on the screen width, the bar width was not a realistic value when there were many items on the X axis. I'll fix this issue. This support enables horizontal scrolling.

  • Touchable Bars

    Touchable Bars

    I would like to touch a bar and display its value in another part of the UI.

    Can you detect a bar touch and pass its data value via touch event as well as dragging across bars and updating the value as you drag?

  • More Customization

    More Customization

    I would like to be able to fit more bars without scrolling. Example: 31 days in a month, 52 weeks in a year. Can you add customization for: min bar width, corner radius. Or reduce widths automatically if scrolling is disabled.

    Also I would like to remove the label above each bar.
