Unable to hide y-axis ticks without extra space

[ridhi58]

Describe the bug
I am trying to hide only yAxis ticks , not y-Axis label in an area chart using "ngx-charts-area-chart".

I couldnt find any input to explicitly hide y-axis ticks only. So, I tried passing empty string to "yAxisTickFormatting" function. It works but still shows a lot of extra space as shown below.

Is there a better way to hide y-axis ticks? If not , how can i reduce the extra space using above solution.
