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....

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.

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...
