Yaxis scale with proper number

henry posted over 12 years ago

Hi ,

When I plot my graph I have on the Yaxis numbers corresponding to the point's value( like -4.5 , -2.4, -1.2 .........). What I want is to have usual number with a step of 0.5 for example (-5 to 2).

How I can do that ?

Hi,

I used our previous sample to illustrate our scenario with my customer settings. The code that I used is:


AxisItem axis1 = new AxisItem();
axis1.Extent = 20;
axis1.DataType = AxisDataType.Numeric;
axis1.Labels.ItemFormatString = "<DATA_VALUE:##.##>";
axis1.OrientationType = AxisNumber.Y_Axis;
 
axis1.RangeType = AxisRangeType.Custom;
axis1.RangeMin = -10;
axis1.RangeMax = 100;
axis1.TickmarkInterval = 20;
axis1.TickmarkStyle = AxisTickStyle.DataInterval;
area.Axes.Add(axis1);

Please take a look at the attached sample and screenshot for more details and let me know if you have any questions.

Regards

I tried this :

            //the layers can share the numeric y axis.
            AxisItem YAxis = new AxisItem(ChartAlphaRealized, AxisNumber.Y_Axis);
            //area.Axes.Clear();
            YAxis.DataType = AxisDataType.Numeric;
            YAxis.OrientationType = AxisNumber.Y_Axis;
            YAxis.MajorGridLines.Visible = false;
            YAxis.RangeType = AxisRangeType.Custom;
            YAxis.RangeMax = 2;
            //if (MinAlphaCumulValue > 0) MinAlphaCumulValue = 0;
            YAxis.RangeMin = -10;
            YAxis.Labels.ItemFormatString = "<DATA_VALUE:##.##>";
            area.Axes.Add(YAxis);

            //the layers can share the numeric y axis.
            AxisItem YAxis2 = new AxisItem(ChartAlphaRealized, AxisNumber.Y2_Axis);
            //area.Axes.Clear();
            YAxis2.DataType = AxisDataType.Numeric;
            YAxis2.Labels.ItemFormat = AxisItemLabelFormat.DataValue;
            YAxis2.MajorGridLines.Visible = false;
            YAxis2.RangeType = AxisRangeType.Custom;
            YAxis2.RangeMax = 30;
            YAxis2.RangeMin = 0;
            YAxis2.LineColor = Color.LightGreen;
            YAxis2.Labels.ItemFormatString = "<DATA_VALUE:##.##>";
            YAxis2.TickmarkInterval = 10;
            area.Axes.Add(YAxis2);

here is the result ( the tickmarinterval is not working for Y2 and it does not work for Y)

Hi,

Maybe one possible approach could be if your are using Range properties. For example:


AxisItem axisY = new AxisItem();
axisY.DataType = AxisDataType.Numeric;
axisY.OrientationType = AxisNumber.Y_Axis;
axisY.Extent = 20;
axisY.RangeType = AxisRangeType.Custom;
axisY.RangeMin = -5;
axisY.RangeMax = 2;
axisY.Labels.ItemFormatString = "<DATA_VALUE:##.##>";
axisY.LineColor = Color.Blue;
area.Axes.Add(axisY);

Let me know if you have any questions.
