Number of bars visible in chart window

[12tkram]

HI NT-8 people ..

I have been looking for the code / variable that holds the number of bars visible in the current chart window ... is this possible ? I have found lots of info on chartbars, but thats all the bars loaded in the chart .. I just need the number of bars visible in the chart window, which could change if I expand or shrink the window etc ..

Any help greatly appreciated as always

Hello 12tkram,

Thanks for your post.

This would be possible by subtracting ChartBars.FromIndex from ChartBars.ToIndex in OnRender().

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
    ClearOutputWindow();
    Print("Bars Visible: " + (ChartBars.ToIndex - ChartBars.FromIndex));
}

Please let me know if you have any questions.

oooo, thats was quick .. brilliant, will give it a go!!!!!!!!!

[12tkram]

yep, that works perfectly .. thanks again, awesome support as per usual!

weirdly though, when I add the OnRender() function all my EMA plots disappear? is that expected?

OnRender() is like a plot override. To also see your plots put this line at the beginning of the OnRender() method:
base.OnRender(chartControl, chartScale);
