TeeChart Charting Library 17.02.21

Steema Software

Beautiful, pre-configured, highly extensible chart and gauge controls for business, engineering, and scientific data.

TeeChart is a charting component library designed to provide you a wide range

of preprepared and configurable charts and charting options for inclusion in your project.

TeeChart provides support for iOS and Android, in either case the syntax for using the component is virtually identical beyond the specific code required to add the chart to the screen view that varies between environments and the interaction syntax for touch and gestures. The example below shows TeeChart being used in an iOS project.

The TChart control inherits from the UIView so it can be added as subview in other views, while other controls, too, can be added to the chart.

using Steema.TeeChart;
using System.Drawing;
...

public override void ViewDidLoad ()
{
    ...

    var chart = new TChart ();
    chart.Frame = new RectangleF (0, 0, 320, 460);
    var pieStyle = new Steema.TeeChart.Styles.Pie ();
    chart.Series.Add (pieStyle);

    // Loading data to the Pie series, we can use Random data just to test
    pieStyle.FillSampleValues (4);

    // or add specific values for the Series
    foreach (int datum in new [] {10, 20, 30, 40})
    pieStyle.Add (datum);

    // Customising our Chart and Series.
    // Setting Chart to 2D and hiding legend
    pieStyle.Aspect.View3D = false;
    pieStyle.Legend.Visible = false;

    // Setting Pie series as Circular, and marks visible
    pieStyle.Circled = true;
    pieStyle.Marks.Visible = true;

    View.AddSubView (chart);
}

Release Notes 1st Jun 2016 TeeChart.NET for iOS version 2016

Build 4.16.05.30

Bugfixes/changes

1) Zoomed event was not called any time, now fixed. You can make use of both Zoomed and UndoneZoom events. Remember that Zoomed event will be called once the pinch is ended, and that the UndoneZoom will be called once the used has done a double tap over the Chart, which resets the zoom. Code example :

tChart1.UndoneZoom += (object sender, EventArgs e) => { tChart1.Chart.Header.Text = "undonezoom"; };

tChart1.Zoomed += (object sender, EventArgs e) => { tChart1.Chart.Header.Text = "zoomed"; }; 2) ClipPoints does not work fine with 2D Series types, this problem appears again and has already been fixed. 3) Drawing image on Canvas by using the Draw method, the image was drawn upside down, now fixed. 4) Zooming over the Series gives a null exception in some cases, now fixed. 5) Improvements for the TeeChartBuilder demo. Removed code for the non Unified version. 6) Improved all texts positions over the Chart, like Series marks, legend texts,.. 7) Some polygons do not draw correctly not closing path of them, now fixed.
8) CircularGauge axis labels were not correctly positioned, now fixed.

Release Notes 1st July 2015 TeeChart.NET for iOS version 2015

Build 4.15.07.01

Bugfixes/changes

There has been an important breaking change inside the TeeChart for Xamarin.iOS. In order to unify as much as possible the NET code for all the available platforms, the iOS library now uses the System.Drawing.Color for all the Color properties. Customers whose recompile their existing apps might get errors related to the Color properties. In that case, the only thing to take care of, is that now the projects must contain the reference to the OpenTK-1.0 library, which is the one which makes possible to use the System.Drawing.Color inside Xamarin projects. Now our library already uses it.

One example of the change could be : Before : tChart1.Panel.Color = UiColor.Blue.CGColor; Now : tChart1.Panel.Color = Color.Blue;
