I'm very new to data transform :( more detailed workflow would be very cool

it is for single bar. I have other banks besides Citi, so taking my example I need to see on the X axis Bank and Y for showing averages

thanks a lot, perfect!

Thanks, that looks good enough. The last thing I'd like to figure out is if it possible to have the actual to projection comparison like it is in one of the Demo charts (last value projection used here). Unfortunately, I don't see "last value projection" in the line + stacked bar chart :(

Thanks. But linear regression will calculate the projected amounts which will be different from what I have. We have calculated projected amounts in excel file and now I just want to illustrate our actuals compared to projected amounts. I will be also good if the projected amount will be total for all expenses I have. So…
