Strange behaviour of Area method

[Anonymous]

Hello!

I am using the mglGraphZB class to plot an "Area" plot:

    mglData* frontsDistributions_;
    mglData* frontsXaxis_;
    ...

Then I make some computations and compute the data and point the two pointers
at it.

    graph_->XRange(*frontsXaxis_, true);
    graph_->YRange(*frontsDistributions_,true);
    graph_->Axis("xy", true);
    graph_->Area(*frontsXaxis_, *frontsDistributions_);

The problem is that the data is plotted differently each time I run the
program. I change only the data, but the coloring also changes.

Sometimes it is such as on the left side and sometimes as on the right side
of:

Moreover, this happens randomly. So for example I run the program two times
with the result on the left, then three times wit h that on the right.

Please what is causing this behaviour?

Thanks

Hello,

It seems that I was using the old documentation. In the new one it is
explained

Also you can use gradient filling if number of specified colors is equal to
2*number of curves.

So I guess this explains this mysterious behaviour.
