How-to-make-indicator-lines-visually-smoother-on-the-charts

The indicators lines on the charts in WealthLab are not showing smooth and look like stair-steps. I know it was like that in WealthLab 6 because that was using very old frameworks. I think I used to see smooth lines in charts in WL7 few weeks backs - don't remember on this exactly, but seems to be. I thought may be I tweaked some settings on my PC. So I checked TradingView.com and their charts do have smooth lines. So it does not look like that I changed some system level settings for this. For comparison, I am adding a screenshot of both WealthLab and TradingView charts:

May be I did some wrong settings in WealthLab? Is there a way to get smooth lines on WealthLab charts?

In my trading workflow and learning/studying trading workflows, I spend probably 90% or more time studying and looking at charts, so the visual and aesthetic aspects do make a big difference.
