To bookmark a chart you first need to click on the "Linkable Version" link located just below the chart and let the page refresh. When you click "Linkable Version", we store a detailed description of your chart in our database and give you back a web address with a "P number" (for example "P123456"). Web addresses with "P numbers" can be bookmarked safely.

For step by step instructions on how to bookmark a chart please refer to this blog article.
