Changing Linera Gauge range?
posted

I have a dashboard i am working on and want to show a linear gauge on the screen.  The data is set as Goal and Actual.  I want to show the actual as a filled in area on the gauge, the Goal as an "arrow" with the max range on the gauge of the goal + 30.  I've added the code below.  The problem is, nothing is showing.  The gauge shows 0-100 and no values on the image.  What did i do wrong?

 

            LinearGauge gauge = this.ugPace.Gauges[0] as LinearGauge;

            LinearGaugeRange range = gauge.Scales[0].Ranges[0];

            LinearGaugeMarker current = gauge.Scales[1].Markers[0];

            LinearGaugeMarker goal = gauge.Scales[2].Markers[0];

            DataTable paceData = PaceData.GetPace();

            double goalnum = Convert.ToDouble(paceData.Rows[0][0].ToString());

            double currentval = Convert.ToDouble(paceData.Rows[0][1].ToString());

            range.EndValue = goalnum + 30;

            current.Value = currentval;

            goal.Value = goalnum;
