I'm using WPS Spreadsheets and want to turn a table into a dynamic chart that can be filtered by conditions (using a PivotChart plus slicers). Please teach me step by step:
1. For each step, write clearly which menu and which button to click;
2. Only give one step at a time, and wait for me to reply "done" before giving the next step;
3. If my table format is not suitable for a PivotTable, first tell me how to organize it;
4. At the end, tell me how to refresh the chart when the data is updated later.

My table has these columns, and the chart I want to see is: [e.g., month, region, product line, sales; I want to see monthly sales and be able to switch by region]
