Draw single TPaletteAxis

Dear ROOT experts,

is there a way to draw a single TPaletteAxis with an arbitrary range, without having a histogram? Something like

    TPaletteAxis *p = new TPaletteAxis(0, 0, 1, 1, NULL);

does not work unfortunately.

If this is not possible, can one draw an empty 2d-histogram with a palette with arbitrary range, such that one can see the palette only? Something like

    TH2F *h2 = new TH2F("h1","h1",100,0,100, 100,0,100);     h2->GetZaxis()->SetRange(0,100); // set range of the palette axis     h2->Draw("COLZ");

seems not to work.

Many thanks in advance for your answers.

Kind regards,
