Label name doesn't appear in vertical axis of the chart

[yabi100]

I have a two column table, column one name of countries column two a number field. Table has 230 rows. Number column is sorted

I draw the chart and in Format axis|Axis options|Labels|Specify interval unit to 1 but some names like Italy doesn't appear in the chart. What shall I do to get Italy in the chart?

Number of rows is 230 and all of them are not fitted in one chart. So I divide them into two charts. first 115 rows are drawn in first chart and the rest are drawn in next chart.
