Description
Is your feature request related to a problem? Please describe.
Horizontal bar charts become less accessible the more entries the have. Especially bars in the Most received from / Most sent to charts get extremely thin, if more than 50 entries are set in the add-on options for the number of contacts shown.
Describe the solution you'd like
Similar to the Expand chart button to increase the width for the first chart, there could be a button to increase the height of horizontal bar charts. Also an export to a text file holding the email addresses and counts would provide the possibility to, see all entries properly.
Describe alternatives you've considered
It's also possible to make the horizontal bar charts vertical and provide a button to increase the width to fullwidth. Or another idea is to give the bars a minimum thickness and make the chart area scrollable.
