Hi QC~

Current axis labels show only 4 points(0, 10, 20, 30),
However I wanna display labels of all data points.

How can i do that ?

[Reference]

dataset = new SimpleDataset("Dataset", xValueList, yValueList);

pTransform = new CartesianCoordinates(ChartObj.LINEAR_SCALE, ChartObj.LINEAR_SCALE);
pTransform.SetScaleStartX(xChartNumericMin);
pTransform.SetScaleStopX(xChartNumericMax);
pTransform.SetScaleStartY(yMinValue);
pTransform.SetScaleStopY(yMaxValue);

xAxis = new LinearAxis(pTransform, ChartObj.X_AXIS);
xAxisLab = new NumericAxisLabels(xAxis);

Thanks ...

You need to override the automatic formatting of the axis by setting some properties of the axis object. You want a tick space of 1, and a major tick mark, and hence a label, at every tick mark.

xAxis = new LinearAxis(pTransform, ChartObj.X_AXIS);
xAxis.AxisTickSpace = 1;
xAxis.AxisMinorTicksPerMajor = 1;

Thanks.

but I still have rest of the problems.

// LinearAxis doesn't have this function
xAxis.AxisTickSpace = 1;

// It works
xAxis.AxisMinorTicksPerMajor = 1;

This is remain problem as below

I want to display like [Pic1] always ...
(Pic2 doesn't show point labels include 1,3,5, ...)
How can I do this ?

What do you mean by the comment:

// LinearAxis doesn't have this function
xAxis.AxisTickSpace = 1;

because the LinearAxis does have the AxisTickSpace property, and you need to set it to 1.0.

You can also try the SetAxisTickSpace method, instead of the property. We tested both in one of our example programs and we know both are accessible.

LinearAxis xAxis = new LinearAxis(pTransform1, ChartObj.X_AXIS);
// the following two lines do the same thing
 xAxis.SetAxisTickSpace(1.0);
 xAxis.AxisTickSpace = 1.0;
 chartVu.AddChartObject(xAxis);
