Excel Dashboard dynamic Chart Development

I'm looking for a bit of help to finish off some dynamic graphs in excel to display our data ranges.

I have graphs linked to data with slicers for filtering etc which is working well.

I need to now implement a scroll bar to the graphs and some buttons or drop down to vary the range displayed between 1 day, a week, month, year that works with the scroll bar, as well as a date selection/picker/entry option.

Also, I'd like to implement a way for a graph to display data in one cell multiple times depending on the value in another cell. For example, if cell 'A' says '100' and cell 'B' says 3, the chart would show '100' three times.

Mainly using bar and line graphs.

Probably one or two other areas to tidy up as well.

Can discuss the payment for this project when we go through it and establish the time involved. There are other things we want to develop that are related that we could bundle into this development for a higher price if suitable.

Thanks
Rich
