FirstBarIndexPainted LastBarIndexPainted equivalent

[habibalex]

In NT7 FirstBarIndexPainted and LastBarIndexPainted were the index of the bar series on the chart. I wanted to verify that this has been updated to :

FirstBarIndexPainted = chartControl.LastSlotPainted - chartControl.SlotsPainted

Hello habibalex,

Thanks for your post.

For most purposes ChartBars.ToIndex and ChartBars.FromIndex should return what you need.

The difference is, chartControl.LastSlotPainted does not look for the last actual bar with information on the chart. This looks for the last slot on the chart, whether or not there is a bar there. This is so that if you have a drawing tool or an indicator and you want to be able to scroll the chart into the blank space after the chart and still be able to calculate using indexes.

The ChartBars.ToIndex will return the index of the last actual bar with information on the chart.
