ZedGraph scrolling left truncates data - scroll

I am using a ZedGraphControl in a WindowsForms project in C#. The ZedGraphControl is V5.1.5.
The data in the control is static and I add it all before the form is shown. The X axis of the data consists of numbers indicating seconds offset from the beginning. in other words from 0 to some number of seconds.
I want to initially show the last 5 seconds, but provide a horizontal scrollbar so the user can scroll back and forth. I set the "graphPane.XAxis.Scale.Max = maxX;" where maxX is the largest X value in my data. I set the "graphPane.XAxis.Scale.Min = maxX - 5;".
The data starts off displaying the way I want it, but when the user scrolls the horizontal bar, bizzar behavior occurs.
As you drag the thumb of the scrollbar to the left, the beginning of the data shown in the grid moves to the lower values as expected, and the thumb of the scrollbar moves to the left, but the right edge of the thumb stays at the right of the scrollbar and you cannot move back to the right. It is as if the data to the right of the viewing range gets truncated as you scroll left.
I cannot find any reason for this nor any way to control it. Does anyone have any ideas about this behavior?

Ok, found it myself.
I found a fine article that describes scrolling:
Add a ScrollBar
In it the author specifically says "the scrolling will be wacky because the scrollable range has not been set".
I used the sample "Manually Setting the Scroll Range" and the part that I was missing is setting the zedGraphControl1.ScrollMinX and zedGraphControl1.ScrollMaxX properties. Once I defined these values everything started working as expected. I also found that in my case, the value of zedGraphControl1.IsAutoScrollRange had no effect, but I left it set to false to be consistent with the example. This would probably have an effect if the dataset is dynamic.

Oracle Reports-How To Add Field Object To Repeating Frame

I want to add field object to an existing repeating frame.But when I drag the field, new frame is generated.
See Image below.
I want to do is put the field F_PO_NUMBER under R_INVOICE frame.
Doble-click on the Paper Layout node.
Touch R_INVOICE repeating frame on the Object Navigator.
Change Fill colour of R_INVOICE by selecting a different than that already has ( colour palette pointers are located on the left side of the Paper Layout ).
Let's choose gray as fill colour, and then there will appear a great gray box on the Paper Layout.
Just drag F_PO_NUMBER to the inside of that gray box. If some frames or objects slides as you drag F_PO_NUMBER, apply immediately an undo by pressing Ctrl+Z, and play with Flex On/Off or Confine On/Off buttons up to your object is able to be removed into that gray box.
I'd suggest you to
create a backup copy of that RDF file - you might need to restore the report if something goes wrong
go to paper layout editor
turn flex OFF (so that frames wouldn't stretch)
select any field in the R_INVOICE frame (for example, F_INVOICE_NUMBER)
copy/paste it (Ctrl+C / Ctrl+V)
a new item (named F_INVOICE_NUMBER1) will be created slightly right & below from the original item)
move it to a new position
if necessary, switch flex ON (and, possibly, confine ON/OFF), but be very careful because you might spoil current layout, and - if you do that - it might be difficult to revert changes. Undo works only 1 level back
change its name & source so that they are appropriate (i.e. F_PO_NUMBER)
save & run the report. Hopefully, it'll be OK.
P.S. As you already have the R_1 frame (which is useless), I'd suggest you to remove (in paper layout editor) it, as well as current F_PO_NUMBER field (visible on your screenshot).

how to show a field in oracle reports at the bottom of the last page which is placed outside the border

how to show a field in oracle reports at the bottom of the last page which is placed outside the border
A trivial answer is: place it outside the border.
I presume you already did that and encountered problems. It would really help if you specified which one(s).
The most usual error is that you're referencing a column at a wrong frequency, i.e. you can't just "move" it outside of its parent frame. (I guess that the frame is what you call a "border".) If that's so, well, you can't do that.
One way out is to create a new column (in the Data Model layout editor) (be it a formula or a placeholder column) which doesn't belong to any group, but is independent. Then you can place it anywhere you want.
If, on the other hand, you do have a formula (or placeholder, or summary) column and "border" you mentioned is the margin, then - while in Paper Layout editor - click the "Margin" icon in the toolbar to switch to ... well, margin layout editor. Now place that field anywhere you want.
Or, did you try to move the field but frames were resized and other fields moved along with the movement of the field you're moving? Pay attention to "Flex" and "Confine" ON/OFF buttons in the toolbar as they make the difference.
If none of above, what is your situation, then?

How to grab the scrolling amount in one window?

This is the first step to scroll two windows simulteneously, the second step is to find a way to apply that amount to the other program. But I really don't know where to start, all I see in from Google is about modifying the behavior of the scroll of the mouse, not the scrolling amount in one window. Advantages of using this instead of listening to the keys:
Scrolling will be seamless since the other program are scrolled in the background
Clicking on the scrollbar works
Different scrolling speeds don't affect the comparison
Moving lines in text editors won't scroll pages in PDF viewers
I can tell you what I would do, but it's not going to be fun...
Assuming the text is roughly evenly distributed (which it might not be between two languages like that, and two windows with different text sizes and widths, really consider this carefully before you do the work), then the goal is to force both scroll bars to be at the same percent relative to their whole. So what you need to do is write a function to determine what percent each scroll bar is at. I would screen capture both windows and crop out the important parts of the scroll bar like this:
Specifically the up and down buttons, the top of the scroll handle, the bottom of the scroll handle. Save them in their own files. Do it for both windows in case they draw their scroll bars a little differently.
Now the tricky part. Write a function that does the following: imagesearch for the top button within rightmost 25 pixels or of the specified window. Same for the bottom button. Same for the top of the handle. Same for the bottom of the handle. Use this to determine where your window is.
SetTitleMatchMode, 2 ; so it matches the end of the title
WinGetPos , X, Y, Width, Height, LibreOffice Writer ;exact substring of window name required
Use something like this to find the scroll bar parts.
CoordMode, Pixel , Screen ;so image search searches entire screen
barwidth = 25 ; make sure it's more than the bar is wide.
ImageSearch, TopButtonX, TopButtonY, X+Width-barwidth , Y, X+Width, Y+Height, TopButton.bmp ; no jpg, fuzzy edges make searches fail
Then do some math, something like:
TopButtonY := TopButtonY+TopButtonImageHeight ; because we only care about the position of the bottom of the button.
BottomHandleY := BottomHandleY+BottomHandleImageHeight ; because we only care about where the bottom of the handle is.
HandleHeight := TopHandleY - BottomHandleY ; how tall the scroll handle is
TotalHeight := TopButtonY - BottomButtonY - HandleHeight ;how tall the scroll field is
HandleOffset := TopHandleY - TopButtonY ;how far it is from the top
HandlePercent := HandleOffset / TotalHeight ; the part we care about. return this value
With a function like that, you can know how scrolled each window is. All that's left is to send the scroll commands. There's a few choices.
; ControlSend , Control, Keys, LibreOffice Writer
ControlSend , Control, {Pgdown}, LibreOffice Writer ; or {Pgup}
ControlSend , Control, {WheelUp}, LibreOffice Writer ; or {wheeldown}
ControlSend , Control, {Up}, LibreOffice Writer ; or {down}
If it lets you move the caret with up/down arrows while the window is inactive, that is probably the most precise option, even if it takes a bit longer. The fastest most precise way is to simulate a click drag also using control send. To use ControlSend you need to figure out which control you're working on. WindowSpy can help you with that.
So first: Find the scroll positions of both windows. Second determine which window is active. Third, nudge the inactive window in the correct direction. Repeat until they're within a certain tolerance range (otherwise it will bounce up and down endlessly).
I can't emphasize this enough, but please make sure that getting the scroll bars in approximately the same positions is sufficiently close before even attempting this. If it isn't, you will have wasted a lot of time fiddling with it. Keep in mind it will be less and less accurate the longer the text is.
If it is an option, I would definitely consider copying the contents of both windows into a program that gives you more access to the controls (or better one that is specialized for this purpose). If you had more access, you could use the paragraph breaks to line up the texts with far more precision.
If you really just want to see both texts side by side (and the paragraphs do line up), you could find a text editor that tells you information like this:
If autohotkey will let you read the text of that information, you can copy the PDF into autohotkey's memory (separated by line) and use autohotkey to show only the corresponding paragraph of the PDF as you move around in the editable document.
Hope something I said helps, good luck.

IcCube - Treefilter without scrollbar and with only limited number of elements

We try to use the treefilter in IcCube to show categories with subcategories. Now we discovered two problems, we don't know, how to fix:
We have 15 categories on level 1, but only the first 11 of them show. There is some space underneath, so it doesn't seem to be cut due to rendering:
We are not able to activate a vertical scrollbar, so when we unfold the tree, there are parts we cannot see anymore. The hotizontal scrollbar is there, but once the tree is too big (image 2) it can't be used anymore as well.
Did we do something wrong and there are options we didn't see, or are our problems due to some bugs in this widget?
Point 1)
Try to increase Max Member Count property on the Query Wizard tab of the widget (this number is for all the members to be managed, not only level 1 items)
Point 2)
Try adding {"cssStyle":"overflow:auto"} in the Content CSS property of the Box tab of the widget.

What to do about this long error: This application is trying to draw a very large combo box

I cannot find any reference to this on SO.. The full message is:
"This application is trying to draw a very large combo box, 32 points
tall. Vertically resizable combo boxes are not supported, but it
happens that 10.4 and previous drew something that looked kind of sort
of okay. The art in 10.5 does not break up in a way that supports
that drawing. To avoid breaking existing apps, NSComboBox in 10.5
will use the 10.4 art for large combo boxes, but it won't exactly
match the rest of the system. This application should be revised to
stop using large combo boxes. This warning will appear once per app
launch."
Any ideas what to do about it?
I made the box in IB, and don't think I did anything special to create it.
I had this same issue. The combo box was in a cell in a table. I changed the row height setting of the table to automatic. But, this gave me an error for not being a valid setting for a cell based table. However, when I reset the table's row height to fixed, the message went away.
More Google searches seem to indicate that this has something to do with the height of the combo box. In my case, the row height of the table increased when I reset it from "Automatic". Perhaps this will give you something to go on.
I had the same error. When I dragged comboboxes out of a Stack View, Xcode messed up their heights. To correct the problem, I added height constraints of 22 to each of them. That caused the warning. When I deleted all the height constraints, the warning went away. The comboboxes didn't revert to the crazy heights they had when I dragged them out.
I've had this forever, but ignored it because I had no idea why it was happening.
From reading the other answers here...
From the storyboard I edited the Combo Box Cell inside the combo box. I changed the Cell Size from Regular to Small and back to Regular.
The problem went away.
