I'm generating a plot like the rasterview example. Sometimes my users data only has one column of information. By default qwt will spread this column out over the entire plot area. So the data always takes up the same width if there is one column or 50 columns. Is there a way to set the width of the columns without also scaling the color map and axes data. I would like to solve this for the screen, exporting to a pdf, and for printing.

This is what I'm getting:

This is what I want:

Thanks
