Here you can find a guide about how to setup a bar chart using FLCharts:


  • Animations for chart bars
  • Customizable Axes (both x and y axis)
  • Dragging / Panning (with touch-gesture)
  • Highlighting values (with customizable popup-views)
  • Create custom cards with embedded chart and more features
  • Scroll through chart while highlighted to change highlighted bar
  • Fully customizable (bar colors, axes color, background, average value, dashed lines, ...)


FLChart is highly customizable. You can choose which property to modify through the .config property.

let axisLabelConfig = FLAxisLabelConfig(color: .black,
                                        font: .preferredFont(forTextStyle: .body))

let config = ChartConfig(axesLabels: axisLabelConfig)
chart.config.dashedLines.color = .darkGray


You can build FLCharts documentation directly in XCode.
In XCode go to Product -> Build Documentation, once XCode has finished building, the documentation will appear.
