Line Annotations On Linear Gauge

[Howard Fore]

Hi,

 

How do I get line annotations to show on my h linear gauge? See XML below:

 

<Chart

editMode='0'

bgColor='FFFFFF'

bgAlpha='0'

showBorder='0'

upperLimit='6.6'

lowerLimit='-8.52'

numberSuffix='%'

gaugeRoundRadius='5'

chartBottomMargin='30'

ticksBelowGauge='0'

placeTicksInside='0'

showGaugeLabels='0'

chartLeftMargin='25'

chartRightMargin='30'

majorTMColor='868F9B'

majorTMHeight='10'

majorTMThickness='2'

majorTMNumber='0'

minorTMNumber='0'

showToolTip='0'

decimals='2'

>

 

<colorRange>

<color minValue='-8.52' maxValue='-0.25' code='ffffff' />

<color minValue='-0.25' maxValue='4.54' code='C8D8EB' />

<color minValue='4.54' maxValue='6.6' code='ffffff' />

</colorRange>

 

<pointers>

<pointer value='3.97'

borderAlpha='100'

bgColor='FFC000'

borderColor='FFC000'

toolText='3 Month Average'

pointerOnTop='0'

pointerRadius='14'

pointerBgAlpha='100'

pointerBgColor='FFC000'

pointerBorderThickness='2'/>

</pointers>

 

 

<annotations>

<annotationGroup id='Grp1' showBelow="0">

<annotation type='line' x='175' y='160' toX='200' color='000000' />

<annotation type='line' x='215' y='155' toX='200' toY='160' color='000000' />

<annotation type='line' x='215' y='165' toX='200' toY='160' color='000000' />

</annotationGroup>

</annotations>

The programming concept of adding and showing line annotation on linear gauge is similar with line annnotation add-on to raster image file:

 

Private Sub button1_Click(sender As Object, e As EventArgs)

Dim obj As LineAnnotation = AnnotationGenerator.CreateLineAnnotation(60F, 45F, 560F, 228F)
'create a new LineAnnotation with start and end point
obj.LinePen = PenGenerator.CreateLinePen(Color.Blue, 5F)
'set line color and width
'set line startcap
obj.LinePen.StartCap = New RasterEdge.Imaging.Annotation.Basic.LineCap()
obj.LinePen.StartCap.Cap_Width = 2F
'set startcap width
obj.LinePen.StartCap.CapStyle = RasterEdge.Imaging.Annotation.LineCapStyle.Diamond
'set startcap style
'set line endcap
obj.LinePen.EndCap = New RasterEdge.Imaging.Annotation.Basic.LineCap()
obj.LinePen.EndCap.Cap_Width = 10F
obj.LinePen.EndCap.CapStyle = RasterEdge.Imaging.Annotation.LineCapStyle.Rectangle

Dim folderName As String = "C:/"
Dim img As Bitmap = obj.CreateAnnotation()
img.Save(folderName & "LineAnnotation.png")
End Sub
