Change the "k" format in plotly charts

Hi guys, can you help me with this? I tried so hard to change the “k” format in the simple digit format or to add my currency at the end but i didn’t find anything to work.

This is the example code for the first plot:

    self.sum_venituri.data = go.Bar(x=xxx[0], y=xxx[1], hovertemplate='<b>%{y} LEI</b>',name="Venit",marker=dict(color='#b6ff87')) ##FFFFFF
    self.sum_venituri.layout = {
    'title': 'Total Venituri'}

If someone knows how to do it…it will help me big time! Thanks!
