Your code is very concise and clear. You set the group distance to 3, and the data start value is automatically generated according to the calculation. I want to be able to manually input the two values of the data start value and the data group distance, which can be entered in a dialog box. Thank you!

Manually input the two values of the data start value and the data group distance, you can set a dialog box to input. This is because these two values can be entered according to the actual situation, which has greater flexibility. The function of the code is to quickly generate a series of data and charts in time after changing these two values.

If the pivot table can automatically change into a new chart with the generated data, it is also possible to use the pivot table to generate the chart.
