SimpleLineChart

SimpleLineChart is a lightweight UIKit line chart view for iOS with simple styling and optional time-range filters.

Features

• UIKit chart view with minimal setup
• Solid or gradient background
• Line styling (stroke, points, shadow)
• Optional period buttons for time-series data
• Multiple datasets per chart

Requirements

• iOS 13.0+
• Swift 5.1+

Usage

Quick start

let values: [SLCData] = [
    SLCData(x: 0, y: 5),
    SLCData(x: 1, y: 7),
    SLCData(x: 2, y: 9)
]

let lineChart = SimpleLineChart()

let dataSet = SLCDataSet(graphPoints: values)
lineChart.loadPoints(dataSet: dataSet)

Styling the chart background

let chartStyle = SLCChartStyle(
    backgroundGradient: false,
    solidBackgroundColor: .white
)
lineChart.setChartStyle(chartStyle: chartStyle)

Styling the chart line

let lineStyle = SLCLineStyle(
    lineColor: .blue,
    lineStroke: 3.0,
    circleDiameter: 5.0,
    lineShadow: true,
    lineShadowgradientStart: .blue,
    lineShadowgradientEnd: .white
)
dataSet.setLineStyle(lineStyle)

Time-series periods (optional)

let chartStyle = SLCChartStyle(addPeriodButtons: true)
lineChart.setChartStyle(chartStyle: chartStyle)

let now = Int(Date().timeIntervalSince1970)
let values = [
    SLCData(x: now - 86400, y: 5),
    SLCData(x: now - 3600, y: 7),
    SLCData(x: now, y: 9)
]

When addPeriodButtons is enabled, SLCData.x must be a UNIX timestamp in seconds for filtering to work correctly.

Multiple datasets

let first = SLCDataSet(graphPoints: values1)
let second = SLCDataSet(graphPoints: values2)
lineChart.loadPoints(dataSets: [first, second])
