I created a csv file with mysqlslap benchmark tool and wanted to plot the AVG, MIN, MAX values. I experimented with the settings of the plugin and I am experiencing some problems to get the correct graph. It seems like there is some syncing problem between the data used for the graph and graph showed (see attachment)

The csv file is produced in a shell command build like this:
echo "LABEL1, LOAD_TYPE, AVG , MIN , MAX, NR_CLIENTS, AVG_NRC_QUERY" > header.txt
mysqlslap -uroot -a --csv=results.csv --concurrency=100 --number-of-queries=10000
cat header.txt results.csv > report.csv
