Try to apply the selections in QlikView and see how many values the chart shows. This is the number of rows NPrinting should show.
So for instance if Page uses the country field, apply the country name of each slide as a filter in QlikView and check how many values are displayed in the chart.
Also, you can use NPrinting functionality in Power Point reports to show only the top 5 values in a chart even if the chart has more than 5 values in QlikView. This will allow you to use a QlikView chart without applying the "show only first X values" to get the result you want.
Do this by using the custom rows functionality in the template editor (see attached image).
