Hi Liga, you cant change the scale of the Y axis as far as I am aware (hopefully this is included in a future enhancement as it would certainly be beneficial). Option A is to either exclude/filter out the item with the 2000 count, then the scaling will be different and your chart will look nicer (but obviously missing one important element of data), option B is to include the data label, i.e. select 'Value' under data label on 'More Chart Options'. It will then insert the number above the bar/column, e.g. 127.
Neither option are perfect but that's the best you can do for now.
Cheers,
Ben
