Dear experts,

I have two questions:
1. I now draw lines (Nlineseries) on a bar chart.But to my surprise, no matter what the X value of the point is, the point series of the line will be always mapped exactly to each bar centers. When it comes to the clustered bars, the point will be mapped to each cluster center.

Actually, when drawing lines on a bar chart, we do not need x values anymore. But what if I want to draw the line with specific X values? Can you help me on that?

2.Another problem is that, I put empty points into the line series (use it as place holder )as the attachment, but the line still goes through them. Would you please help on that?

Many thanks and Await your reply
