`Hi Team, `
`i have given Min value =900 and max Value=1200 but its showing error ? `
`this value is correct right ? `
` `
` `
`<``telerik:RadialGauge` `x:Name``=``"radialGauge"` `Width``=``"300"` `Height``=``"300"``> `
`            ``<``telerik:RadialScale` `Min``=``"900"`  `Max``=``"1200"` `MajorTickStep``=``"200"``> `
`                ``<``telerik:IndicatorList``> `
`                    ``<``telerik:Needle` `Value``=``"1000"` `/> `
`                ``</``telerik:IndicatorList``> `
`            ``</``telerik:RadialScale``> `
`        ``</``telerik:RadialGauge``> `
` `
`Please let me know  `
`Thanks, `
`Sara`

Hello Saravanan,

The scale has got 0-100 as its Min-Max by default. So, when you set Min as 900 then it is greater than 100 (default Max value). In this case I would recommend to set the Max value before the Min. The sample code is below:
`<``telerik:RadialGauge` `x:Name``=``"radialGauge"` `Width``=``"300"` `Height``=``"300"``> `
`            ``<``telerik:RadialScale` `Max``=``"1200"` `Min``=``"900"` `MajorTickStep``=``"200"``> `
`                ``<``telerik:IndicatorList``> `
`                    ``<``telerik:Needle` `Value``=``"1000"` `/> `
`                ``</``telerik:IndicatorList``> `
`            ``</``telerik:RadialScale``> `
`</``telerik:RadialGauge``>`

All the best,

Hello Saravanan,

You always can change format of the tick mark labels using RadialScale.Label property. For example:

`<``telerik:RadGauge` `x:Name``=``"radGauge"``>`
`    ``<``telerik:RadialGauge``>`
`        ``<``telerik:RadialScale` `x:Name``=``"linearScale"`
`                 ``Max``=``"10000"`
`                 ``Min``=``"1000"`
`                 ``MajorTickStep``=``"1000"``>`
`            ``<``telerik:RadialScale.Label``>`
`                ``<``telerik:LabelProperties` `Foreground``=``"Red"` `Format``=``"{}{0:0,}K"`  `/>`
`            ``</``telerik:RadialScale.Label``>`
`            ``<``telerik:IndicatorList``>`
`                ``<``telerik:Needle` `/>`
`            ``</``telerik:IndicatorList``>`
`        ``</``telerik:RadialScale``>`
`    ``</``telerik:RadialGauge``>`
`</``telerik:RadGauge``>`
