In this post , I will shown an example on how to display all labels on the X-axis (Horizontal axis)  in SSRS charts .

Below query is going to be my dataset

DECLARE @SalesbyMonth TABLE (Months VARCHAR(20),Sales INT,MonthNo INT)
INSERT @SalesbyMonth SELECT 'January',1000,1
INSERT @SalesbyMonth SELECT 'February',100,2
INSERT @SalesbyMonth SELECT 'March',100,3
INSERT @SalesbyMonth SELECT 'April',200,4
INSERT @SalesbyMonth SELECT 'May',500,5
INSERT @SalesbyMonth SELECT 'June',800,6
INSERT @SalesbyMonth SELECT 'July',500,7
INSERT @SalesbyMonth SELECT 'August',100,8
INSERT @SalesbyMonth SELECT 'September',900,9
INSERT @SalesbyMonth SELECT 'October',600,110
INSERT @SalesbyMonth SELECT 'November',100,11
INSERT @SalesbyMonth SELECT 'December',100,12
SELECT * FROM @SalesbyMonth

Create Column chart with Sales as summation value and Months as Category Groups
