Bubble Charts - Some Bubbles are Partially Visible

$
0
0
I am trying to construct a bubble charts from the following set of data:

Region Score 1 Score 2 Size
A 100 100 150000
B 65 80 50000
D 70 50 80000
E 80 60 90000
F 45 10 60000

Assumptions:

All scores in Score 1 and Score 2 columns must be between 0-100

The entire chart must be visually divided into four identical quadrants (BCC Matrix approach)

These quadrants bust be fixed along mid-ranking values:
-Horizontal boundaries: 0-50-100
-Vertical Boundaries: 0-50-100

In order to achieve the following assumptions I have formatted both vertical and horizontal axis in the following manner:

Minimum – 0.0
Maximum – 100
Major Unit – 50
Minor Unit – 10
All the above values are made fixed in the Format Axis window.

When I plotted chart I have experienced two sorts of problems:

Issue 1:
Bubbles that come close to the boundaries of plotting areas are only partially visible. For example, due to its top scores Region A bubble will be plotted in the top right corner of the chart – and only a quarter of the bubble will be visible.

Is there a VBA code (or any other way) to make the rest of the bubble visible (taking into consideration all assumptions outlined above? I have seen some adds-in that can accommodate this requirement but I could not allocate any macros or formula that can do the same.

Issue 2:
Some bubbles overlap across each other.

Is there a way to make bubbles’ colour fills translucent? Once again, some adds-in would allow for this but I need a VBA code.

I have attached an excel file that fully describe my problem and solutions sought.
any thanks in advance.

David
