Note that this means some extra layout work when you want to render your plots using QwtPlotRenderer. 2) Check the plotmatrix example like recommended by Andre.

These graphs are calling the same constructor which contains following lines: setFixedHeight(300); setMinimumWidth(150); But the output is a little bit ugly (see attachment) because we want the qwt plot and legend to be aligned. For example, i would like legend items for graph 'Rows' and 'Files' to be of the same width; and X Axis for these two graphs also have the same width. Is it possible to achieve this goal? Any help is appreciated.

So please check these SVN branches. This one should already been solved in both SVN branches, The solution was to reorder the inlined methods. AFAIR these errors are from debug statements nobody is interested in. I guess it would be best to throw them away or to use some conversion, where you don't need any cast at all ( f.e using %p ). Please send me a patch ( for trunk + 6.0 ) - I don't have any 64-bit environment myself.

(I did see a dllimport warning with "bool QwtInterval::isValid() const" in qwt_interval.h, but not an error. I patched by making it inline as it had been in some previous version.

The code works fine with g++ 4.6.2 and 4.5.1 ( the versions on my systems ). When this patch really avoids the compiler error it l looks more like a problem of the compiler itself, than of the code. Could you please try to spend some time on finding out if this is a g++ 4.7.0 bug ( maybe ask on the g++ support channels ) or if there is something reasonable we have not understood yet ? Instead of your patch I would prefer replacing the const_cast by a C cast. Does g++ 4.7.0 accept this ? Uploading small patches like yours to sourceforge ( or here ) is o.k.

For example, if you have 5 curves in your plot refreshing let's say at 10Hz, then if you replot() each time new data is appended to each curve you will have 10 * 5 replots per second. Maybe it is enough to externally trigger a replot at 10Hz where the 5 curves are updated together... thus reducing the load by 5 times... 2. If you add one point at time in your curves, use incremental painting as in the incremental plot example in qwt distribution examples. 3. Our major problems used to derive from graphical devices connected to 4 or 6 screens. Enabling Xinerama on the Nvidia X driver helped improving this situation.

The value is converted to a plain text using QLocale::system().toString(value). This method is often overloaded by applications to have individual labels. Parameters: value Value Returns: Label string. Reimplemented in QwtDialScaleDraw. So I guess you are going to have to subclass QwtScaleDraw (not necessarily QwtAbstractScaleDraw) and implement your version of label()... Kind regards, Hendrik Am Mittwoch, 9.

It is not 100% clear to me what you are trying to achieve and what you mean by "weired" (of course, I have a rough idea, but we have to precise here in order to best solve your problem). My best guess is fixed heights of the plots in the scroll widget. And my other guess is that you feel the plots are pretty wide and squeezed vertically. To achieve this, you probably want to use setFixedHeight() in the constructor (so that you have the plots' dimensions fixed in the direction of scrolling) and setMinimumWidth() for the other direction. It might also be that 100 is a bit too small a height (try 250 or so...?). Kind regards, Hendrik Am Mittwoch, 9.

One solution to this is to resize every second the arrays that hold the points, append the new values and call again the |setRawSamples()| and the |replot()|, but this solution is not memory efficient as at every second I have to store at least 2 * 2048 points.
