OnRender numbers grid per bar at bottom of chart

[pjsmith]

Hi,

I find myself wanting to add a series of boxes with numbers in them at the bottom of the chart window, 1 per bar, per the volume ladder chart statistics etc. Before I spent hours trying to code this, I wondered if there are any code examples someone can point me to? I'm guessing someone has already done this. No point re-inventing the wheel, so to speak. I've had a look around and whilst there are plenty of indicators that do this,I can't find any example code. If anyone can point to some, I'd be grateful. Thanks,

Hello pjsmith,

The ChartBars.FromIndex and .ToIndex provide the bars on the chart.

You can get a bar's index by time if you want a specific bar.

You can convert the bar indexes to x coordinates or convert bar times to the x coordinate with the ChartControl methods.

You can convert prices to y values with the ChartScale.

Most drawing tools included with NinjaTrader use these tools to draw over specific bars on the chart. You can use these for examples.
