You can Compare two members of your clan by their XP in each skill by first selecting a member from the Clan Members list, then choosing a second member in the compare interface that appears below the list, or by following the same procedure on the Friend List if both friends are Clan Stats members.

A page will open that is similar to the compare feature of the official RuneScape highscores but with a little more information. You can hover over the arrow icons too see how much more or less XP one member has than the other. Below that is a box for each selected member containing interesting stats about them.

Finally, if both members allow you access in their Privacy Options, you will see an activity line graph, which shows the XP activity of both selected members for the entire time they have been added to Clan Stats. It initially shows overall (total) activity, but you can change the skill it shows using the select box below the graph. You can also change the maximum activity shown by changing the limit, if either of the selected members gained more XP than the limit the line will go off the chart.

Below that is a progress line graph showing the XP progress of the selected member for the entire time they have been added to Clan Stats. Like the activity graph, it initially shows overall (total) progress which can be changed using the skill select box below the graph.

You can change the size of either graph image by clicking the image itself or by choosing a size in the select box below the image.
