Sort sequence for chart and chart size for A.OLAP

Dear Experts,

I am a fresh man to Analysis office

I created some analysis document in our BIP 4.0 SP5 environment

But I found two strange points, would you kindly help to me resolve it

1. I use three measures to create stack horizontal bar chart in A.OLAP. Would you kindly let me know what's the sort sequence for this chart? Let us say we have below data

City    GSV ISV QTY

A          10    12   10

B           15   15   20

C           10   5     5

So in my side, I saw City B is in 1st position then City A, city C in the chart

So if I want to see C,A,B, or customizing sequence, how do I achieve this?

2. Which will determine the chart size. We have two chart, one chart contains 3 measures and one chart contains 2 measure. Both of them are with one analysis dimension and using stack horizontal bar chart. But the chart with 3 measures, its size is large for each category comparing 2 measure. Is there any method to adjust it? Please check attach the screen

Best regards

Alex yang
