use OnRender on an indicator's panel

Done. This did it:
y = GetYByValue(0) - 17.618f;

Thanks for your reply. I got it working; the problem was, since I want y-axis to be below 0 line if macd > 0 (and vice versa), I was assigning 0 directly to y-axis instead of GetYByValue(0). It works perfectly (if macd > 0) as it adjusts automatically as I scroll forwards or back; the same for charts with shorter or longer time frame.

The problem now is when macd < 0, the text should be drawn just above the 0 line. I need a y-axis that behaves like GetYByValue(0) but above the 0 line. Assigning a constant value like GetYByValue(1.618) does not produce the same effect as GetYByValue(0), as the text moves out of proportion when scrolling through the chart.

Hello satoyama,

Thanks for your post.

When you modify your MACD with OnRender() coding, it will use the panel that the MACD is assigned to when the indicator is loaded.

You have to open de samplecustomplot in the ninjasctipr editor. It is in the INDICATOR folder.

Thanks for your reply. SampleCustomPlot is mention in the link, it sends me to NT8 help guide, but I don't see link to the sample script itself.

Hi !

You have this little thread with some answer. You should use the correct chartpanel. It seems the answer is in the samplecustomplot indicator. Take a llok at it.

This question has been probably asked but it is difficult to find the right answer. The question is, how do I use OnRender on an indicator's panel.
As an example, I have a modified MACD and I can use DrawText to draw the Hi and Low values on the zero line of the bar. But I want to use OnRender instead of DrawText.
I don't need instructions on how to use OnRender, just on how to send output to MACD's panel.
Thanks in advance.
