Hi,

I have a CircularGauge with three pointers displaying a pressure value. One pointer Shows the actual value, one shows the minimum and one shows the maximum.
values are also displayed in Labels.
Everything was ok until I upgraded my project from Essential Studio 14.1.0.41 to 14.3.0.49.
Now my all Show the same value (the current pressure). The Labels bound to the same data Show the correct values.
Here is my Code:

this.BindingContext = pressureMeasurementData;

 

Grid grid = new Grid {

VerticalOptions = LayoutOptions.FillAndExpand,

RowDefinitions =

{

new RowDefinition { Height = GridLength.Auto },

new RowDefinition { Height = GridLength.Auto },

new RowDefinition { Height = GridLength.Auto },

new RowDefinition { Height = GridLength.Auto },

new RowDefinition { Height = GridLength.Auto }

},

ColumnDefinitions =

{

new ColumnDefinition { Width = GridLength.Auto },

new ColumnDefinition { Width = GridLength.Auto }

}

};

grid.Children.Add(new Label {

Text = "Pressure"

}, 1, 1);

grid.Children.Add(new Label {

Text = "Min"

}, 1, 2);

grid.Children.Add(new Label {

Text = "Max"

}, 1, 3);

grid.Children.Add(new Label {

Text = "Unit"

}, 1, 4);

Label pressureLabel = new Label();

pressureLabel.SetBinding(Label.TextProperty, "Pressure");

grid.Children.Add(pressureLabel, 2, 1);

Label minLabel = new Label() { Text = "Min", TextColor= Color.Green };

minLabel.SetBinding(Label.TextProperty, "Min");

grid.Children.Add(minLabel, 2, 2);

Label maxLabel = new Label() { Text = "Max", TextColor = Color.Red };

maxLabel.SetBinding(Label.TextProperty, "Max");

grid.Children.Add(maxLabel, 2, 3);

grid.Children.Add(new Label {

Text = "bar"

}, 2, 4);

SfCircularGauge circularGauge = new SfCircularGauge();

circularGauge.HorizontalOptions = LayoutOptions.CenterAndExpand;

Scale scale = new Scale();

scale.StartValue = 0;

scale.EndValue = 100;

scale.Interval = 10;

scale.StartAngle = 135;

scale.SweepAngle = 270;

scale.RimThickness = 10;

scale.RimColor = Color.Gray;

scale.MinorTicksPerInterval = 4;

scale.LabelColor = Color.Black;

scale.LabelFontSize = 15;

scale.MajorTickSettings.Color = Color.Black;

scale.MinorTickSettings.Color = Color.Black;

scale.LabelOffset = 0.1;

NeedlePointer needlePointer = new NeedlePointer();

needlePointer.Color = Color.Black;

needlePointer.KnobColor = Color.Black;

needlePointer.Thickness = 2;

needlePointer.KnobRadius = 10;

needlePointer.LengthFactor = 0.7;

needlePointer.SetBinding(NeedlePointer.ValueProperty, "Pressure");

scale.Pointers.Add(needlePointer);

NeedlePointer minPointer = new NeedlePointer();

minPointer.Color = Color.Green;

minPointer.KnobColor = Color.Black;

minPointer.Thickness = 1;

minPointer.KnobRadius = 10;

minPointer.LengthFactor = 0.6;

minPointer.SetBinding(NeedlePointer.ValueProperty, "Min");

scale.Pointers.Add(minPointer);

NeedlePointer maxPointer = new NeedlePointer();

maxPointer.Color = Color.Red;

maxPointer.KnobColor = Color.Black;

maxPointer.Thickness = 1;

maxPointer.KnobRadius = 10;

maxPointer.LengthFactor = 0.6;

maxPointer.SetBinding(NeedlePointer.ValueProperty, "Max");

scale.Pointers.Add(maxPointer);

circularGauge.Scales.Add(scale);

grid.Children.Add(circularGauge, 1, 5);

Grid.SetColumnSpan(circularGauge,2);

Content = grid;

What am I doing wrong?
