Re: Xamarin License Issue

Hi, The production product uses the older portable classes for the PCL project but the newer test app that works uses .NET standard classes. Hi, this shouldn't be a problem (to use older portable classes), as it uses the same procedure. Did you use any other TeeChart for Xamarin.Forms version (Pro ...

Re: TeeChart for Xamarin.iOS 4.16.12.12 available

Hello roey, I'm sorry, I'm not sure what are you trying to accomplish. You should be able to change the bar width by using the CustomBarWidth property : bar.CustomBarWidth = 30; Using code, similar to the code I used on my last post : public override void ViewDidLoad() { base.ViewDidLoad(); tChart =...

Re: Draw Rectangle based on DateTime

Hello, I did a mistake passing the left parameter in the draw rectangle method. The following code works fine even if you pan over the Chart. You can also draw several rectangles (areas). private void Chart_BeforeDrawSeries(object sender, Steema.TeeChart.Drawing.Graphics3D g) { var tmpHour = Utils.G...

Re: Draw Rectangle based on DateTime

Hello, you could do it by using the OnBeforeDrawSeries event, for example : Chart.BeforeDrawSeries += Chart_BeforeDrawSeries; private void Chart_BeforeDrawSeries(object sender, Steema.TeeChart.Drawing.Graphics3D g) { var tmpHour = Utils.GetDateTimeStep(DateTimeSteps.OneHour); Rectangle rect = Chart....

Re: How to limit pinch-and-zoom in Xamarin

Hello Robert, we've already added a new OnPinch event for Xamarin.Forms. It'll be available for the next maintenance release which will be published very soon. But, in meantime you could use the OnBeforeDrawAxes event in order to check the minimum and maximum axis values and force a setMinMax for ax...

Re: TeeChart for Xamarin.iOS 4.16.12.12 available

Hi roey, you should be able to do this by using the OnBeforeDrawPoint event of Series. Here an example : var bar = new Steema.TeeChart.Styles.Bar(); bar.Marks.Visible = false; Chart.Series.Add(bar); bar.FillSampleValues(4); bar.Pen.Color = Color.Red; bar.BeforeDrawPoint += Bar_BeforeDrawPoint; priva...

You can always set a value to MaxPointsPerPage property, this will automatically separate the number of points by different pages allowing to scroll by panning, or by using specific buttons to call for previous or next page.

Re: Xamarin.iOS Legend Checkbox behaviour

Hello, ok,TeeChart for Xamarin.iOS allows custom drawing on canvas by using the onafterdraw event (draw shapes with colors, texts, etc..), but due to limitations for this specific platform I would suggest to create your own legend at the desired position (just below the Chart for example) by using a...
