Relate mouse click position to points on graphs

I am working with labview 7, on windows XP. I am trying to relate between a mouse click on a waveform chart to a point on the chart. All I managed to do so far is relate with a cursor, but the cursor has to be dragged and I want the user just to click on the graph. Is that possible?

Hello
Attached is a labview example lv 7.0 about how to map cursor coordinates to graph units.
Perhaps Chilly Charly can post his vis en 7.0
Greetings

How to get the mouse clicked positions on a movie

I am doing a project on Objects tracking
I am capturing the video data using webcamera and playing it using processor in JMF
my problem is , if i click on the movie that is being played currently, i have to display the co-ordinates of the mouse clicked position.
can anyone help me?
Thanks in advance

u can click on the image and get the mouse co-ordinates
i have also got the pixel values of the current frame at which u had clicked the mark button..do some manipulation on the pixels to get ur stuff work

Determine mouse click position on jps page

hi ........ i'm developing registration web application using Jsp and want to determine the user mouse click position on frame.......... how can i do it using jps

I used to have a lengthy JSP page, which has lot of list boxes. When I click one list box, the other list box value is depend on the previous one. so, I post the form and when I come back it used to scroll at the top. I used to below code to resolve it. I called scrollingPos() fn in list boxes onchange event.
     function scrollingPos(){
          //store the scrolling position in the hidden (whichpos)
          var mypos = 0;
          mypos = document.body.scrollTop;
          document.forms[0].whichpos.value = mypos;
     function gohere() {
          //while loading form, get the 'whichpos' value from the server and pass to scrollTo
          var thispos = '<%= scrollpos %>';
          window.scrollTo(0,thispos);
          thispos = 0;
<html:hidden name="mainForm" property="whichpos"/>

Mouse click position on Glass Pane

Hi,
I'm working on a program following this example about Glass Panes:
http://java.sun.com/docs/books/tutorial/uiswing/components/rootpane.html
I'm having a problem whith code to detect the component I click on:
Point glassPanePoint = e.getPoint();
Container container = contentPane;
Point containerPoint = SwingUtilities.convertPoint(
                                glassPane,
                                glassPanePoint,
                                contentPane);
if (containerPoint.y < 0) { //we're not in the content pane
    //Could have special code to handle mouse events over
    //the menu bar or non-system window decorations, such as
    //the ones provided by the Java look and feel.
} else {
    //The mouse event is probably over the content pane.
    //Find out exactly which component it's over.
    Component component =
        SwingUtilities.getDeepestComponentAt(
                                container,
                                containerPoint.x,
                                containerPoint.y);
}I don't know if is e.getPoint(), SwingUtilities.convertPoint or SwingUtilities.getDeepestComponentAt, but
getDeepestComponentAt doesn't return the component I click on. It returns the component which is a little bit down
on screen.
Anyone has the same problem and knows how to avoit it?
Thanks

The problem was frame borders. With this adjustments works properly:
final Window window = SwingUtilities.getWindowAncestor(this);
final Container container = getRootPane().getContentPane();
final Point pWindow = window.getLocationOnScreen();
final Point pContainer = container.getLocationOnScreen();
final int iAdjustmentX = (int)pContainer.getX() - (int)pWindow.getX();
final int iAdjustmentY = (int)pContainer.getY() - (int)pWindow.getY();
final MouseEvent mouseEvent = (MouseEvent)event;
final Point pMouse = mouseEvent.getPoint();
final Point glassPanePoint = new Point((int)pMouse.getX() - iAdjustmentX, (int)pMouse.getY() - iAdjustmentY);

Mplayer seek to mouse click position

Can any one tell me what to put in the mplayer config file so that i click on the video anywhere and the video should continue from there.
Just like ffplay has this option.
I have seen the seek option but its either relative of absoulte. But does not consider the positon of the mouse

WorMzy wrote:^ Does the community package have that? I've just discovered that the -git package has it, and rushed here to inform OP. You don't even need to modify any config files, it's enabled by default.
Are you talking about mpv GUI "overlay"? Yes, I'm using the one from [community].

Xy graph in GUI. Show string data related to a X,Y point

It is possible to show string data, while hovering the mouse or clicking a cursor, attached/related to a X,Y point in a XY graph??
Kind regards

I assume you want to let the x-y-value pair hover over the graph at mouse position.Perhaps this will help you:
http://forums.ni.com/t5/LabVIEW/Text-overlay-annotation-onto-an-intensity-graph/m-p/883438/highlight...
Another option might be just to use the cursor functionalities of XY graphs, although they don't hover at mouse position.
Other than that I had a similar request on Image Displays with IMAQ (Vision Development Module) where it turned out that using a simple string control from the classic palette that you move around according to mouse position is an efficient way to let information hover wherever you want. Check it out:

Looking up the values in a waveform graph with a mouse click

Hi,
Does anyone know how to look up the values in a waveform graph with a mouse
click but... without the cursor legend on, if i press in the waveform graph
nothing happens, i must search my cursors and only then i can see the values
of my signal data?! Isn't there any other way?
Best regards,
Thijs Boerée

Dear Chad,
I know of the function "bring cursor to center". I also figured out that
when i use a property node of the cursor array of clusters, that i can see
that some values change when i move the cursor (i can see the X and Y scale
value change of the graph and also the values of the mouse pointer (in
points due to screen resolution)) But in this cluster i can't set the mouse
position. I allready made a VI where i can see the bounds of my
waveformgraph and I have the Xscale (min and max) and the Yscale (min and
max), with a linear fit i can translate my mouse position to X an Y scale
values and when i click on my waveform graph the cursor go's to that
position (property node of the cursor position), only disadvantage is that i
only have the bounds of my plot area and not the position, i do have the
position of my waveform graph but the plot area isn't allways in the center,
if i could extract the position of the plot area i may find a solution to
solve this problem.
And to file a product question:
I would like to see the function that with a mouse click a little menu
appears and that there are options to for example set a marker on that data
and when you right click on it, that there are options to remove it or to
add comment, a 2D array could make a list of the different channels with
it's markers (time stamps and comments).
Best regards,
And thank you for your help.

Buggy mouse cursor position (Jumps around to random spot on mouse click)

I've only noticed this annoying quirk in photoshop CS4. This only happens when using the tools in photoshop, and not in any other programs.
When using the tools in photoshop, every so often, some times more often then others, the tools will jump to a random place on (and many times FARE off) screen on mouse click. As in the tool is no longer where my mouse is, but is registering elsewheer.
A few examples. Working with the pen tool to line something, click a control point to set it, go to click to set another one and that point is now being dragged around well off my screen even though the mouse pointer is on screen.
Using the brush tool to color something in and click and the brush is coloring fare above my curser.
Select something and the selection is jumping here and there each time, go to crop? Click and drag and the grabed part jumps off screen.
It is random as to when it wants to jump, and where it wants to jump. Some times it happens all the time, others every so often, or times not at all,.
No settings are ever changed reguarding the mouse, it's just random and ONLY in photoshop with using it's tools. My mouse it's self is not jumping, just where the tool is drawing/putting down whatever is.
This jumping also seems to be a rather common thing, as I stream my drawing live at times and when it starts doing this I've had many people comment and remark that their copy also does the same thing. Posting a journal entry about it also resaulted in a lot of replies with people facing the same thing.
Is this a bug in CS4? People have told me to check my mouse settings under the control panel but that shouldn't have anything to do with it when every other program I use does not do this yet photoshop does. Flash don't, dreamweaver don't, illustrator don't. Painter, bryce, max, etc etc none of them do it. Only photoshop and only when I am using a tool. It's effects are still random.

Hi,
I have the same problem as well. I don't think it's related to the mouse hardware at all- on mine the mouse curser stays in the same position but Photoshop registeres is elsewhere! If I let go (of holding the mouse button), the mouse is still where I left it. I've had this problem since Photoshop CS4 x64 but the problem still happens on Photoshop CS5 x64 (it was fine at first but after about a month of use now CS5 has started having the same problem).
I've had the problem for a while (almost a year now) and is really annoying! I dont have any tablets, and I've changed my mouse a few times. I am using a laptop with Windows Ultimate x64. It only happens in photoshop, it's fine in Adobe InDesign.
Hopefully someone might come up with a solution!
Thanks to anyone who can help me/us

How do I Get the value from a mouse click - on a waveform graph?

If I have made a plot into a Waveform Graph and later want to do a zoom of my data
(Not zoom into the Waveform Graph, but regenerate the data). How do I read the mouse
coordinate if I click on the graph window. I know how to put up the horiz and vert
cursors but don't know how to just read the mouse click. I would really like to
follow the windows standard that identifys a rectangle by clicking and draging and then
be able to read the corners of the rectangle. Thanks, Rick
PS: Using Labview 6i

I would recommend to 'translate' your graph in a picture and dislay it in a picture control (see picture examples in LV6).
Once you did it, pictures have an extremely useful property called Mouse that returns the mouse coordinates and click events when you place the cursor on the picture.
By this you can re-arrange the graph on picture appearance.
There are also other methods such as using a Window's API that returns the mouse position referred to the whole screen window, but I believe this would be much more difficult to implement.
Let me know if this was clear and if you need an example vi.
Good luck,
Alberto

WAD 7.0: Mouse click events on graphs?

I'm using BEx Web Application Designer 7.0 and was wondering what type of options are available in terms of event handling for the graphs themselves (line graphs in my case) within a Web Template?
What I'm getting at is, I notice when I click on a point on one of my line graphs after execution it takes me to the top of the page. Does this mean these graphs are interactive with mouse events? Would I be able to setup a function that when a point on a line on the graph is clicked, instead of it jumping me to the top of the page I could set my drilldown item to automatically set a filter for the "0CUSTOMER" characteristic that line represents, so my graph then only displays that line and not the other 4? My first assumption is this might be possible using javascript?
If more information or explanation is needed please let me know. Or if you have links to references explaining this that'd be great as well. Thanks for the help!

Filtering by right-clicking on a series on the line graph and picking either "Keep Filter Value" or "Keep Filter Value on Axis" seems to produce unwanted results. Often the graph will dissappear and a placeholder where the graph should be will display "No data available". Or, it will display just the single series I selected but erases the legend, so there is no way to tell which Customer Region was chosen to be displayed if anyone but the interacting user were to look at it. The only way to get proper results is to right click on a series and choose "Select Filter Value" and go through a Variable Selection screen, which is actually the step I am trying to shortcut.
I'm thinking the other options, "Keep Filter Value" and "Keep Filter Value on Axis" aren't working quite right due to the hierarchies that are being used so I may just need to play around with it for a while. But like I said above, my main goal of all this is to be able to skip the process of having to go through the Variable Selection screen, and simply left or right-click on a series or line and be able to select and display just that line, which is where I think I may need to turn to JavaScript?
But as always, I appreciate the help!

Mouse click point is not accurate

Has anyone ever had an issue with the mouse click coordinates not being accurate? For example, when I click on my canvas with the Rectangular Selection Tool, the point being clicked is actually 10 pixels below where the mouse is pointing! It causes much unnecessary headache...
Thanks for reading!

How about giving some relevant information (see link)?

If you work on CS4 you could rotate through the Screen Modes (hit F three times) to correct the issue, which occurs when opening or creating a file in Full Screen Mode.

Mouse click on graph without event handling

Is there a way to detect mouse click on a graph without the event handling? My base version of LabVIEW does not have event handling features.
Thanks,
Ryan
Solved!
Go to Solution.

Leaving out the Event Structure seems like cruel and unusual punishment. My scorn is divided about 80/20 between NI for selling it and whoever tried to save a few bucks by buying it and then sticking it to you to workaround. Perhaps you are a student in which case you are free labor and it is all good.
Maybe your boss is a purist and dislikes Event Structures because they break the dataflow paradigm. The alternative is of course polling, and in this case you have plenty of data flowing! Unfortunately 99.9% of it is worthless. Here is a little example in LV8.2 (don't know your version) that uses polling to check on the mouse button. I only added a simple check for the button being pressed, if you want to know click (down/up) you can add a shift register and look for transitions in the button. I do check that the front panel is up front, otherwise it will still register clicks even though you may be surfing the web.
Hopefully everything is in the base package.

How to make mouse change position on click?

So, I'm trying to make a gun aim at the crosshair, so it follows the mouse all the time. I want it to go up on recoil, so the mouse crosshair goes up and the gun follows up.
I tried something like mouseY - 10; but with no luck, it didn't do anything. Thanks.

you can't control the users mouse. you can 'hide' the users mouse and use a crosshair movieclip to indicate where the mouse is positioned and that movieclip you can control.

Tool changes to pointer on mouse click

Help! All of a sudden when I use a tool in Photoshop CS4 the brush size or selection tool changes to the arrow on mouse click. I see the brush tip or eraser tip, but when I hold the mouse down it changes to an arrow.

I had this happening too under CS4 with Snow Leopard.
I went to preferences / cursors, and changed the cursors options, then changed them back, and it fixed it.

Mouse clicks retina

Since upgrading to the latest 10.8.2 update, left mouse clicks via the track pad or usb mouse and the mouses position on screen are not recognized. to remedy the issue, I often have to open and close the laptop's display multiple times before the computer recogized position or left clicks. Right clicks are always recognized.
I do many presentations using my machine - this is super frustrating!
In addition, sometimes the mouse click will get stuck in the down position - regardless of mouse device plugged in.
So I unable to release objects that are being drag'n dropped. Browser windows especially.

I'm assuming you have already rebooted the unit at some point and tested. If you have then I would also look at resetting the SMC and testing again. If there is still a problem then I would test in a new user on the Mac and see if the issue ocurrs there also.
If it does then boot to your Recovery Partition and test it there. If none of this makes any difference then you may have to look at reinstalling the OS to see if that makes a change. It sounds HW based right now but it could quite conceivably be SW related as the issue only started after an update.
If you do end up reinstalling the OS then test it right away in 10.8 and make sure everything is fine. If it is then you could go online and manually download 10.8.1 and make sure it's fine there also. If it is again then I would possible avoid 10.8.2 as it would appear at that point that it was the cause of the issue.
If you do all of the above and even after the reinstall there is a problem then you would need to try erasing the HD and reinstalling. If after that there is still an issue then it is a HW problem and you will need to take the Mac into an Apple Store or Service Provider to get it serviced.
