Examples with RrdGraph org.jrobin.graph.RrdGraph used on opensource projects

Example 1 with RrdGraph

use of org.jrobin.graph.RrdGraph in project opennms by OpenNMS.

the class JRobinRrdStrategy method createGraphReturnDetails.

/**
     * {@inheritDoc}
     *
     * This constructs a graphDef by parsing the rrdtool style command and using
     * the values to create the JRobin graphDef. It does not understand the 'AT
     * style' time arguments however. Also there may be some rrdtool parameters
     * that it does not understand. These will be ignored. The graphDef will be
     * used to construct an RrdGraph and a PNG image will be created. An input
     * stream returning the bytes of the PNG image is returned.

             * available if no graphing commands were used, e.g.: if we only
             * use PRINT or if the user goofs up a graph definition.

             * RrdGraphDetails.getInputStream and no graphing commands were
             * used.  If they just call RrdGraphDetails.getPrintLines, though,
             * we don't want to throw an exception.
