Remove Vertical Lines from AMCHARTS Grid and keep Horizontal lines

Question

My question is about a specific Graphs and Charts Building Tool call AMCHARTS. I am using their live editor to build a Graph, and I need to remove the vertical lines (leave the horizontal lines only) from the chart grid.

Is it possible to do so?

thanks,

Answer 1

Just in case someone is still looking for the answer:

//disable horizontal lines    
valueAxis.renderer.grid.template.strokeWidth = 0;

//disable vertical lines
categoryAxis.renderer.grid.template.strokeWidth = 0;

Answer 2

just change "categoryAxis"

"categoryAxis": {
     "gridThickness": 0
},

Thanks.
