HH and LL's

[atlas]

Hi, I was wondering if there was a way to achieve this in a chart with labels, like in Ensign?

I tried to modify zig-zag, but it seems like a few labels are missing:

Hello Atlas,

The bars you have circled in your image simply did not meet any of the criteria that draws the labels. If you add a debug statement and print out the bar index when each condition in the formula draws a label, you will see that they match the bar index locations of the labels that appear on the chart.



To have the extra bars you've highlighted receive a label, you need to either add another condition or modify the existing conditions.

Hmm...It doesn't work in real-time. The HH and LL's are correct, but the labels get shifted if I reload. Each time I reload, and there is a new bar, the labels get shifted to left by one. I tried drawTextRelative and it is worse.

Hello atlas,

Doesn't look like the original code was written for real time updating. Try changing all of the drawTextAbsolute() calls to drawTextRelative() and replace the variable used for the x-coordinate from RPPoint to 0.
