Labels disappear

[Grtjn]

Hi all,

I just created a halfcircle radgauge using the Q1 2010 version.
The problem I have is that my labels get stuck in the border of this gauge (shown in the attached image)

This is the code for my radgauge:

RadGauge radgauge = (FindName((e.Result as RadGaugeData).XAMLNaam) as RadGauge);

                if ((e.Result as RadGaugeData).Visible)
                {
                    radgauge.Visibility = System.Windows.Visibility.Visible;
                }
                else
                {
                    radgauge.Visibility = System.Windows.Visibility.Collapsed;
                }


                RadialGauge gauge = new RadialGauge()
                {
                    MaxHeight = 100,
                    MaxWidth = 175
                };
                radgauge.Content = gauge;
                RadialScale scale = new RadialScale()
                {
                    Min = (e.Result as RadGaugeData).ScaleMin,
                    Max = (e.Result as RadGaugeData).ScaleMax,
                    //StartAngle = 180,
                    //SweepAngle = 180,
                    IsLogarithmic = false,
                    MajorTickStep = (e.Result as RadGaugeData).TickStep,
                    //MiddleTicks = 5,
                    LabelRotationModeLabelRotationMode = LabelRotationMode.None,
                    Location = ScaleObjectLocation.OverInside
                };
                scale.MiddleTick.Length = 0.08;
                scale.MajorTick.Length = 0.1;
                gauge.Items.Add(scale);

                ColorConverter converter = new ColorConverter();
                SolidColorBrush lowcol = converter.getSolidColorBrushFromString((e.Result as RadGaugeData).ColorLow);
                SolidColorBrush medcol = converter.getSolidColorBrushFromString((e.Result as RadGaugeData).ColorMed);
                SolidColorBrush highcol = converter.getSolidColorBrushFromString((e.Result as RadGaugeData).ColorHigh);

                scale.Ranges.Add(new RadialRange()
                {
                    Min = (e.Result as RadGaugeData).ScaleMin,
                    Max = (e.Result as RadGaugeData).LowTresHold,
                    Location = ScaleObjectLocation.Inside,
                    StartWidth = 0.05,
                    EndWidth = 0.1,
                    Background = lowcol
                });
                scale.Ranges.Add(new RadialRange()
                {
                    Min = (e.Result as RadGaugeData).LowTresHold,
                    Max = (e.Result as RadGaugeData).HighTresHold,
                    Location = ScaleObjectLocation.Inside,
                    StartWidth = 0.1,
                    EndWidth = 0.15,
                    Background = medcol
                });
                scale.Ranges.Add(new RadialRange()
                {
                    Min = (e.Result as RadGaugeData).HighTresHold,
                    Max = (e.Result as RadGaugeData).ScaleMax,
                    Location = ScaleObjectLocation.Inside,
                    StartWidth = 0.15,
                    EndWidth = 0.2,
                    Background = highcol
                });

                Needle ndl = new Needle()
                {
                    Location = ScaleObjectLocation.CenterInside,
                    IsAnimated = true,
                    Value = (e.Result as RadGaugeData).Waarde,
                    //Background = new SolidColorBrush(Colors.Red),
                    TooltipFormat = "{0:F2}"
                };
                var uri = new Uri("/Telerik.Windows.Controls.Gauge;component/Themes/generic.xaml", UriKind.Relative);
                var dictionary = new ResourceDictionary();
                dictionary.Source = uri;
                if (dictionary.Contains("RadialGaugeHalfCircleNStyle"))
                {
                    gauge.Style = dictionary["RadialGaugeHalfCircleNStyle"] as Style;
                }
                if (dictionary.Contains("RadialScaleHalfCircleNStyle"))
                {
                    scale.Style = dictionary["RadialScaleHalfCircleNStyle"] as Style;
                }
                scale.Indicators.Add(ndl);

                String RGTitel = (e.Result as RadGaugeData).XAMLNaam;
                TextBlock TargetBlock = new TextBlock();
                if (RGTitel == "rg1")
                    TargetBlock = tb1;
                else if (RGTitel == "rg2")
                    TargetBlock = tb2;
                else if (RGTitel == "rg3")
                    TargetBlock = tb3;
                else if (RGTitel == "rg4")
                    TargetBlock = tb4;
                else if (RGTitel == "rg5")
                    TargetBlock = tb5;
                TargetBlock.Text = (e.Result as RadGaugeData).Titel;

And Location = ScaleObjectLocation.OverInside did not do the trick...

Any help ?

Kind regards,

Gertjan

Hi Grtjn,

The default values for some properties doesn't fit in you scenario. There are several possible solutions of the problem:

• set smaller Radius to the RadialScale = 1.15 or less
• change the Location of the Labels to Inside and make the Location=Outside for all RadialRange elements
• set FontSize=8 and Offset=-0.07 for the Labels

Just play with some of these properties and find the solution which is the most appropriate for your case.

Hope this helps.
