Toggle candlesticks visibility on button click

[singjay]

For a strategy, how can we code to toggle the visibility of candlesticks on a button click? A sample code would be helpful. Thanks.

Hello singjay,

Setting the BarBrush and CandleOutlineBrush to transparent would hide the candles. You would need to loop through all of the bars on the chart.

Below is a link to a User App Share script that hides the chart bars.

As well as a link to an example with button clicks.

Thanks for the code example. It helped but the last current candle is still showing. How to hide that one as well? See screenshot.

Hello singjay,

Calculate.OnPriceChange / .OnEachTick.

Thanks this helped. Btw, the strategy was not hiding all the candles. It was hiding only subsequent candles after the button click, not historical bars. I've to put this part separately in a custom indicator for now. If it works from a strategy please provide a quick sample code, it would help. Thanks.

Hello singjay,

To loop through all bars and set the brush to transparent.

for (index = 0; index < CurrentBar; index++)
{
BarBrushes[index] = Brushes.Transparent;
}

If this is called from a button click or any non-data-driven method, be sure to call TriggerCustomEvent first as demonstrated in the example script I have provided.

I'll try this one out. Thanks much!
