Make a browser plot.
Place cursor in middle of X range and use Z key to zoom in.
==> Auto Rescale Y has been checked in the Browser panel menu, but still the Y axis does not rescale to make use of available space to see each curve clearly.
An action menu item has been added: “Rescale - Y Only“, which can be used to force rescaling Y Only. Also added the accelerator key “Ctrl + Shift + R“ to rescale any graph Y only.
