How do we change the icon of chart legend?

[yashcena]

I have a line chart where the icons of the legend are a circle with a line. I want to change that to a square or a bullet.

Can this be done?

Seems, This is not a bar chart. Looks like Combo / Line chart we can say

And you have option called Display Options. There you need to change like below from expression Tab

I think you have enabled both line and Symbol in your expression ..Go to Expression and un-check the symbol if not required ....or change it to the symbol format which you required
