Thanks for the reply.
You may have noticed that when ever you generate a Bar chart (nothing to do with EPPLUS at this stage) in EXCEL the data (bars) plotted is from highest row bar coming at the top of the chart and the first row bar coming at the bottom.
E.g If the data range is A1:A15, the A15 bar shall be plotted at the top and A1 at the bottom.
In orde to change this, excel provides a feature which I have mentioned in my previous post (right click on Y-Axis, Click Axis option and click the check box "Categories in reverse Order") which reverses the order and First row bar comes to top and
last row bar goes to bottom in the chart.
I was wondering if there is an option in EPPLUS, which I can use after generating the EXCEL and before saving it in my code (c#).
I hope it is now clear.
