I would like to add to my project a statistics section, with charts, ecc. Searching in the forum I found links to wysota's charts, and Qwt. Since wysota's project implements only barchart I have downloaded qwt; it is very complete and powerful. I have made a simple application just to try it and learn the basics.

My problem is this: my application should read data from a magazine database and get for each issue the number of a certain type of article (for example, reviews): so, Gen 07 - 5 reviews, Feb 07 - 3 reviews, Mar 07 - 5 reviews, etc, and build a line chart. Get the data is not the problem; it is have on x-axis the sequence of issues (Gen 07, Feb 07, Mar 07, ecc) instead of a numerical progression.

Thanks
