AChartEngine click event, after sliding demand point index

AChartEngine line chart click

Recent projects used in drawing the chart function, visual only okay with this plugin, but encountered the following problem:

After sliding to the left at some point is hidden, just click on a point, the resulting index is not at this point in the array index, what is the solution? Great God help qq 78783606 beg beg for help! Grateful
