I am attempting to incorporate the % symbol after the value of 100
or -100
on the yAxis in the chart shown above.
I made an attempt to add the % symbols as follows:
quotes.data.frequency_counts[i].negative = Math.round(negative * -1)+'%';
quotes.data.frequency_counts[i].positive = Math.round(positive)+'%';
However, I encountered an error indicating that strings are not permitted as data_points. While I understand this limitation, I am still hopeful that there is a solution to display the % sign for user clarity on the information being presented.
This application does not belong to me, but rather it is a HighChart that can be edited within plunker: http://plnkr.co/edit/8mDQD1?p=preview
