We still do not have an answer to this question:
We want to understand this better. So there are charts from a previous Chartbook still displaying? Or these charts belong to the Chartbook you switched to? What Chartbook do those charts belong to? Do they belong to the Chartbook, you switched away from or the one you switched to? When I switch chartbook, the bottom half of the screen (such as the 2 intraday charts) maintains the view of the 2 intraday charts belonging to the previous chartbook. Example; I am on chartbook 1, let's call it ZN with all its own charts. I switch to chartbook 2, let's call it ZW. After the switch from ZN to ZW, the lower half of the screen maintains the view of chartbook 1 (such as ZN) even though I am now on chartbook 2. Essentially, I see the upper half of the screen showing chartbook 2 (correct and expected behaviours) while the lower half of the screen won't change, remaining on chartbook 1 (definitely something wrong). At this point I see the upper half of the screen of chartbook 2 with ZW, while the lower half of the screen showing (still) ZN Then, IF I hover the mouse over the lower half of the screen, the 2 intraday charts belonging to the previous chartbook (such as chartbook 1) simply disappears, leaving a dark space on the screen as shown in the screenshot I sent. Example: I was viewing NQ → I switch to ZC → the upper section correctly updates to ZC, but the bottom two charts remain stuck on NQ.
So in this ZC Chartbook, are there charts in the same position for the ZC Chartbook where you see the charts that are blank? Every single chartbook (Chartbook 1,2,3,4, etc) use the exact same framework with the exact same layout. The only thing that is different across them is the volume-base chart which needs to be adjusted (i.e. 1K vol for NQ, 4K for ZN, etc) based upon the volume exchanged. Other than that they are identical. So the answer to this question is yes, there are 2 charts where I see the blank space in each and every chartbook. Are you using OpenGL?
Yes I do, I find it very beneficial for distributing the load off of the GPU instead of rendering the charts with the CPU. Regarding, post # 11 if we can get the two Chartbooks, NQ and ZC, we will test those. Otherwise, we have no ideas about this.
No problem at all, I attached them for you. However, those 2 chartbooks are just an example. In instance #4 I have 6 different chartbooks and it happens, from time to time, on all of them, so I don't think the issue is these 2 chartbooks but I am no genius here... With all this being said, I also tried to switch Global Setting -> General Setting -> GUI -> Destroy Chart Windows When Hidden -> to Yes and I can tell this behaviour stopped happening. It's just a little sluggish when I switch to load up all the charts but it's just a very minor issue compared to the issue we're trying to figure out :) Let me know if you need something else and I'll provide it for you. Thanks for the huge help here, really appreciate it. Fabio |
