Not all labels on x-axis are showing in sql server 2008 report

Here is my problem. The bar chart report is showing da开发者_如何转开发ta on x and y axis (y axis has 3 fields - min, max, avg values for time frame) and x axis has task type.

fixed out the issue! had to set the interval of the axis properties to 1
