Hi, fong_ui:
There is a VI named
"Word_set_scale.vi"
inside
..\National instruments xxx\VI.LIB\ADDONS\_OFFICE\_WORDSUB.LLB
That is called to set the scale of a chart.
If you open it, you will see that only "minimumscale" and "maximumscale" are set.
You can add another property, named "CrossesAt" and set it's value to "minimumscale"
Notice that if you change and save this VI you will be modifying ReportGenerationToolkit, so every VI that call to "Word_set_scale.vi" will follow the modified version.
Hope it helps,
Aitortxo.
