Updating the last Candlestick entry.

I see lots of issues and resolutions for realtime charts that use addEntry and notifyDataSetChanged and that is all fine and good.

What about updating the current last entry. Say I have a 30 minute bar with open,high,low, close.

If it is 10:15am I will be getting updated prices of that bar for the next 15 minutes and I do not want to add an entry until 10:30am when the new bar starts. What I want to do is check the current price that comes in, several times in a minute, and update the open,high,low, close of the 10:00am bar if necessary.

So I was thinking that I could pop the last entry off then addEntry to add it back it with the new values then notifyDataSetChanged. Unless there is a better way than that?

you just get whatever data you want and simply re-create the data or just update your entry, and then refresh the chart.
If you take a look at draw() method, it simply render everything
