You may get a situation while creating charts that some vertical bars of the chart have very low value than other vertical bars so that the bars having low value are almost invisible. In those situations you can enable Scale Breaks.
E.g. In the chart below Sales Amount of United States for a company is much higher as compared to other countries. The sales report is generated with respect to the highest sales. The blue bars of another countries like Germany and Australia is very low with respect to United States.
To make the lower bars visible , you can enable scale breaks. The steps to enable scale break are written below.
