# Showing Bootstrap Support

We use a tree saved in `json` format from a 100 replicate bootstrap resamplings. The `show_support=True` argument controls whether or not to display support. The `threshold=0.8` argument indicates only nodes with a support level ≤0.8 will have support text displayed.

## Change the placement of support text

The support text is positioned relative to the `x`, `y` coordinates of the tree node. Control over support text placement is achieved using the `support_xshift` and `support_yshift` attributes. These are expressed in terms of pixels.

To place the support text internal to the node, we set the `yshift=0` (so at the same y-value of the node) and xshift it to the right using a positive integer.
