 Please help! Is it possible to align the scale of secondary axis with data point on xyChart? |

Hi all:
I'm using C# on setting the scales of secondary asix along with data points on a xy-chart like attached pic shown. lables(A,B,C,D and E) are mapping to its corresponding data point on PLAN asix)
I'm wonder if it is possible because I've checked all functions included in xAxis2() API. For example, setLabelGap() only allows to set an equal distanct between each axis lable.
Please help me if there is any other soluction, thanks a lot.

Hi Yalin,
You can use the top x-axis and then use Axis.addMark to add the labels to any position you like. For example:
c.xAxis2().syncAxis(c.xAxis()); //The top x-axis has the same scale as the bottom x-axis
c.xAxis2().setColors(Chart.Transparent, Chart.Transparent); //hide original labels
string[] myLabels = {"A", "B", "C", "D", "E"};
for (int i = 0; i < 5; ++i)
c.xAxis2().addMark(myXData[i], -1, myLabels[i]).setMarkColor(Chart.Transparent, 0x000000, Chart.Transparent);
Hope this can help.
Regards

Thanks Kwan, it's a clever idea!
But I have another question:
In this case, does ChartDirector support drawing "scale line" for mark on axis?
Or maybe I need to get the x y coordinate of each mark for drawing its corresponding tick?
I show it on the picture, thanks.

I've solved this issue by myself.
by using:
for (int i = 0; i < MeasurePointsWithWafer.Count; i++)
{
Mark aMark = chart.xAxis2().addMark(DataX[i], 1, DataY[i]);
aMark.setMarkColor(Chart.Transparent, 0x000000, 0x000000);
