The steps are like this.
1. Make data columns and use icons to make the data you want to display.
2. Click the Add Chart icon on WPS, and select data columns and chart styles according to the prompts. There are hints all the way, basically at first sight.
As for the problem of removing horizontal or vertical lines, this is much simpler. Click the stencil line or vertical line, right-click and choose Clear.
The above hope can help you. You can also go to the WPS forum, where there are some illustrated tutorials.
