Hi Everyone

I have a chart that looks good if I've only got a few items on the category
(x) axis (for days). However when I include more days the height of the chart
decreases leaving a lot of white space at the top and bottom of the chart. I
have increased the chart size but this only helps a bit.

I think what I need to do is somehow change the feature that automatically
sets the vertical scale so I can set it to manual. I realise that this will
change the relationship between the X and Y axis but this is what I want to
do.

Hope this make sense and someone can help

Thank you

Matt
