<![CDATA[How to set a series of strings as x-axis in QChart?]]>I have a series of strings in the x column, and corresponding values in the y column. I want to plot y versus x in a line chart, and I want each neighboring x labels has the same interval. How can I achieve this? Thank you.

I have solved my problem after read through the example.

Actually, I should have three columns. the first column is just a series of sequential integer numbers, the second column stores the cateogories, which will be appeared as the x axis labels, and the third column stores y-axis values. Then I create a QBarCategoryAxis, e.g. xAxis, then I append the xAxis with the categories column, and link the xAxis with my line series (i.e. setAxisX(xAxis, series).
