====== Making charts ======
{{indexmenu_n>1}}
Please check that you have at least one full day statistics before making the chart.

For your convenience, we created the scripts that automatically find top N protocols or directions (independent systems) and create a profile that plots each of them in an own color.

To start the script to build a profile with top protocols:
<code>
/usr/local/nfsen/bin/create_top_protocols --consumers 8 --divide-up-down --profile-name top_8_protocols
</code>
Here:\\
consumers 8 - is a number of protocols to plot (max. 10)\\
divide-up-down - means that inbound and outbound traffics are represented above and below zero axis\\
profile-name top_8_protocols - is the name of the profile to create((A profile is selected in the top right corner of NFSEN window. If you can not select the recently created profile: please use 'Stat' mark in the upper line.)).

The script creates a profile named top_8_protocols. This profile makes charts with top 8 protocols by traffic are shown in different colors:

Protocols that were not included in "top" are collected into "others" and have the same color. 
This profile is convenient to build reports by protocols as described in chapter [[nfsen_ext_reports|Making reports]].

You can also keep only those protocols that you are interested to see. To use this method, please uncheck the "extra" protocols in "Statistics" window placed below the charts.\\
Example: only torrents remain in the chart:

Similarly, one executes the script to build a profile with top directions:
<code>
/usr/local/nfsen/bin/create_top_directions --consumers 10 --divide-up-down --profile-name top_10_directions
</code>

The script creates a profile named top_10_directions. You can visually see,  for example, the difference in traffic volumes of GOOGLE and FACEBOOK in this chart.
