Even using the *Simple Data Writer*, this is beyond the capability of JMeter's inbuilt graphics package and is too much to import to Excel. attachment:throughput-graph.png |

It reduces a 3-hour test run to 180 data points which is much easier to represent with a chart program such as Excel. BR The script uses a few neat awk tricks, such as:
