Remove space between axis and plot

Better upload a screenshot of what you want to do.

Hi,

plot.png

Here you can see that the points with 0.0 on the x axis are not on but above the axis. I hope it is getting clearer now.

Please add gridlines for the y axis ( maybe in red ) and set the canvas background to cyan and upload another screenshot.

Hi,

Where you can see, that the zero line ( 0 at y left ) is exactly the first pixel in the canvas.

You could disable the backbone of the scales ( see QwtScaleDraw ) and draw a line at y=0 inside the canvas - if this is what you want to do.
