Announcements

9-7-2017 - Version 4:

Version 4 was released which adds multiple plots, dynamic reloading of values, more reference line customisation options and various bug fixes.

You can see the major changes in the API here.

The public interface is incompatible with previous versions. If you prefer to keep using the older version, make sure to specify version 3 in your podfile or downloaded the classes from a pre-v4 release.

About

Example Application Usage

An adaptive scrollable graph view for iOS to visualise simple discrete datasets. Written in Swift. Originally written for a small personal project.

The main goal of the this graph component is to visualise simple discrete datasets and allow the the user to scroll through the graph.

Usage

Adding the ScrollableGraphView to your project:

Add the

ScrollableGraphView
class to your project. There are two ways to add the ScrollableGraphView to your project.

Manually

Add all of the files in the Classes directory to your project in Xcode to your project in Xcode.

CocoaPods

Add

pod 'ScrollableGraphView'
to your Podfile and then make sure to
import ScrollableGraphView
in your code.

Carthage

Add

github "philackm/ScrollableGraphView" ~> 4.0.2
to your Cartfile and then make sure to link the frameworks and
import ScrollableGraphView
in your code.

Creating a graph and providing it with data.

  1. Create a ScrollableGraphView instance. The graph requires a data source, which is an object that conforms to the

    ScrollableGraphViewDataSource
    protocol.
    // Compose the graph view by creating a graph, then adding any plots
    // and reference lines before adding the graph to the view hierarchy.
    let graphView = ScrollableGraphView(frame: frame, dataSource: self)
    
    

    let linePlot = LinePlot(identifier: "line") // Identifier should be unique for each plot. let referenceLines = ReferenceLines()

    graphView.addPlot(plot: linePlot) graphView.addReferenceLines(referenceLines: referenceLines)

  2. Ensure the dataSource object conforms to the

    ScrollableGraphViewDataSource
    protocol and implements the following three methods like so:
    func value(forPlot plot: Plot, atIndex pointIndex: Int) -> Double {
        // Return the data for each plot.
        switch(plot.identifier) { 
        case "line":
            return linePlotData[pointIndex]
        default:
            return 0
        }
    }
    
    

    func label(atIndex pointIndex: Int) -> String { return "FEB (pointIndex)" }

    func numberOfPoints() -> Int { return numberOfDataPointsInGraph }

  3. Finally, add the ScrollableGraphView to the view hierarchy.

    someViewController.view.addSubview(graphView)
    

This will create a graph that looks something like:

SimpleGraph

Interface Builder support

There is now support for Interface Builder (from CocoaPod version 2.0.0). See the example project in the folder: graphviewexampleib

Things you could use it for:

  • ✔ Study applications to show time studied/etc
  • ✔ Weather applications
  • ✔ Prototyping
  • Simple data visualisation

Things you shouldn't/cannot use it for:

  • ✘ Rigorous statistical software
  • ✘ Important & complex data visualisation
  • ✘ Graphing continuous mathematical functions

Customisation

The entire graph is composed by initially creating an empty

ScrollableGraphView
object and progressively adding whatever plots and reference lines you require.

Create a plot using the any of the

LinePlot
,
DotPlot
,
BarPlot
constructors. Create reference lines using the
ReferenceLines()
constructor. Before adding the
ScrollableGraphView
object to the view hierarchy, add the plots and reference lines to the graph using the
addPlot
and
addReferenceLines
methods. You can add multiple plots (examples are shown below). Each plot must have the same number of data points.

In the case of interface builder, graph customisation is performed via the properties pane, whilst plots and reference lines customisation is done in the corresponding view controller. See the example project in the folder: graphviewexampleib

Graph Customisation

These settings can be set directly on the

ScrollableGraphView
object before adding it to the view hierarchy.

Adapting & Animations

| Property | Description | |---------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | shouldAdaptRange: Bool | Whether or not the y-axis' range should adapt to the points that are visible on screen. This means if there are only 5 points visible on screen at any given time, the maximum on the y-axis will be the maximum of those 5 points. This is updated automatically as the user scrolls along the graph. Adapting| | shouldAnimateOnAdapt: Bool | If

shouldAdaptRange
is set to true then this specifies whether or not the points on the graph should animate to their new positions. Default is set to
true
. Looks very janky if set to
false
. | | shouldAnimateOnStartup: Bool | Whether or not the graph should animate to their positions when the graph is first displayed. |

Spacing

In points. | | leftmostPointPadding: CGFloat | How far the first point on the graph should be placed from the left hand side of the view. | | rightmostPointPadding: CGFloat | How far the final point on the graph should be placed from the right hand side of the view. | | dataPointSpacing: CGFloat | How much space should be between each data point. | | direction: ScrollableGraphViewDirection | Which way the user is expected to scroll from. Possible values:

, the graph will start on the "right hand side" of the graph and the user will have to scroll towards the left. |

Graph Range

| Property | Description | |--------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | rangeMin: Double | The minimum value for the y-axis. This is ignored when

shouldAdaptRange
=
true
| | rangeMax: Double | The maximum value for the y-axis. This is ignored when
shouldAdaptRange
=
true
| | shouldRangeAlwaysStartAtZero: Bool | Forces the graph's minimum to always be zero. Used in conjunction with
shouldAdaptRange
, if you want to force the minimum to stay at 0 rather than the detected minimum. |

Plot Customisation

For all plots you can specify animation related information for when the plot first appears and during adaptions.

Animation

| Property | Description | |---------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | animationDuration: Double | How long the animation should take.

blueDotPlot.adaptAnimationType = ScrollableGraphViewAnimationType.elastic

// Setup the second plot. let orangeLinePlot = LinePlot(identifier: "multiOrange")

orangeLinePlot.lineColor = UIColor.colorFromHex(hexString: "#ff7d78") orangeLinePlot.adaptAnimationType = ScrollableGraphViewAnimationType.elastic

// squares on the line let orangeSquarePlot = DotPlot(identifier: "multiOrangeSquare") orangeSquarePlot.dataPointType = ScrollableGraphViewDataPointType.square orangeSquarePlot.dataPointSize = 5 orangeSquarePlot.dataPointFillColor = UIColor.colorFromHex(hexString: "#ff7d78")

referenceLines.dataPointLabelColor = UIColor.white.withAlphaComponent(1)

// Setup the graph graphView.backgroundFillColor = UIColor.colorFromHex(hexString: "#333333")

graphView.dataPointSpacing = 80

graphView.shouldAnimateOnStartup = true graphView.shouldAdaptRange = true graphView.shouldRangeAlwaysStartAtZero = true

// Add everything to the graph. graphView.addReferenceLines(referenceLines: referenceLines) graphView.addPlot(plot: blueLinePlot) graphView.addPlot(plot: blueDotPlot) graphView.addPlot(plot: orangeLinePlot) graphView.addPlot(plot: orangeSquarePlot)

Known Issues

  • Some aspects of the graph cannot be customised after it has been added to the view hierarchy.
  • Reloading the graph with a different number of data items is currently not supported.
  • Performance in the simulator is not great.

If you find any bugs please create an issue on Github.
