Dear experts,

I have several questions about bar chart and line.

1. As the attachment shows(please refer to Q1), currently I use NFunctionCalculator to draw some lines. However, when it comes to the clustered bar, the default line position especially the point location is not suitable. How can I map the line position to the corresponding bar series?

2. Does nevron support the function of drawing a linear trend line of bars as the excel does? If so, how can I access this function?

3. If I want to get the X coordinate of each bar center, especially for clustered bars, how to calculate it?

Thank you for your consideration.

Looking forward to your reply!
