## Setting the Displayed Color Label Length for a Bubble Chart

If the legend of a bubble chart contains many color labels, the labels may be truncated. You can extend the displayed color label length by doing the following:

1. Edit the `<`PPM_Home`>/server/<`PPM_Server_Name`>/deploy/dashboard.war/static/app/portlet/css/BubbleChart.css` file:

   1. Find the `maxLegendItemLength` key and increase its value. The value is in pixels. About 1,000 pixels is equal to the 200 character color label length limit.

   2. Save the file.

2. Repeat Step 1 for all nodes in a cluster.

3. Restart the PPM Server.
