As the chart to the right shows, this means + that you can now easily set the left/right/top/bottom gutters independently. This makes it easy to give + yourself the space that you need for labels, which will be most noticeable with the Bar chart, the Line chart + and similar chart types. There is another example on the <a href="../examples/hbar.html#gutter-example">HBar example page</a>. + </p> + + <p> + Because of the fundamental nature of this change (every chart type has been affected) + you should rigorously test your charts if you choose to upgrade. + </p> + + <p> + The new properties are: + </p> + + <ul> + <li>chart.gutter.left</li> + <li>chart.gutter.right</li> + <li>chart.gutter.top</li> + <li>chart.gutter.bottom</li> + </ul> + + <p> + They all default to 25 pixels (with a few exceptions) and each can be set independently. + </p> + + <p> + These new properties eliminate the need for certain others.
