How to calculate something using equation from Chart' directly?
I have some equation that gerenarted from the trendline in the chart (Power
equation). The other iteration want to use the formula directly from the
chart. Somehow I don't know how to do that since I can't find in the Help.

Use LINEST to get the values into cells
