Heart rate not shown in statistic graph

When I monitor the heart beat max min average and also calories are shown in the statistics and seem to be plausible.
However the graph does not show the heart beats.
Do I need to change any settings?
I have version 4.8.25.

It works for me. Are you sure that you are ticking the "Heart Beats" check box? It is next to altitude below the Sections divider.

Hi Orux,

in earlier versions it also worked on my smartphone. But after some Updates the graph is not shown anymore.
It seemed that with the Update some settings were lost. So I supposed that the reason for this are missing settings.
Is it senseful and possible to send you an export of that track that you could check the problem?

Best Regards
