Graph scale value change

This seems like a silly thing, but I have a VI with 2 graphs on the front, and when I go to change the scale on the Y axis (X is auto-scaled), I can't just type in the number and hit enter. I can type in the number and hit ctrl-enter, and I can type in the number and click off the graph and it works, but I can't type it in and just press enter.
Anybody know how to fix this?
Thanks!

Hello,
Since you cannot reproduce the issue, it sounds like you may have some corruption in your VI. I would suggest replacing the graphs or copying the VI into a new document. Please post back if you have further questions or this does not work for you.
Was the "old" VI written in LabVIEW 8.0 as well?

Programatically edit graph scale

Hi,
I kow that I can edit graph scale values simply mouse clicking on them, and typing new values.
Now I want to reproduce this behaviour programatically, but the problem is that I can't use the mouse in my application (only keyboard is available )
So, is there a way to programatically get focus to scale boundaries (x_min, x_max, y_min, y_max)?
I hope so...
I need to programatically setting them.

I'd have suggested this too - but you may be limited. Imagine you have set your control to increment by 0.01 (for precision reasons) - how long may it take if you want to set a value of 50?
By the way - building a num pad is not that complicated. Of course it takes time to accomplish, but I think you are most flexible.

Change the Business Graphic Y-axis from decimal scale value to integer

Hi,
I am trying to get rid of the decimal points of the Y axis scale to integer.
The scale value is currently showing like below:
13.86
10.395
6.93
3.465
(This actual data set is currently fall between 3.xxxx to 12.xxxx)
I want the scale label to display in integer, like this:
15
12
9
6
3
or
13
10
6
3
This is determined dynamically as I have made the below settings.I am mapping the seriesSource of the Percentage BusinessGraphic to a node of attributes type of decimal.
In the Chart Designer, I am setting the Y Value Axis configuration as below:
Minimum value: 0
Minumum calculation: Automatic
Maximum value: 100
Maximum Calculation: Automatic
Can you advise me how I can control the graph Y axis scale label to display in integer while I am mapping to a node of decimal data (for percentage values)?
Thanks,
KC

Hi, Poojith.
After making the below change:
1. The "Scaling Type" in the "Value Axis" of the Chart Designer is Linear.
2. I converted the type of the attribute bound to the SimpleSeries to new Decimal(double)
I am still not able to achieve what I want. I am checking the value of the Value Axis --> Line --> Format.
Based on the field description ("Specifies the format of the label output"), it seems like it is the value I should change. It is currently BLANK.
Let me try it out. Please advise if you have any information on the Format string pattern I should use.
Thanks,
Kent

In chart (graph), How to set scale value dynamically(user input scale val.)

Hi ,
I am using Crystal Reports XI R2.
I have specified scale value but user is asking he can decide scale value while running the chart like Y-axis major interval (inclement by) 10, 7, 4, .5, .25 etc.
How to achieve this please give me suggestions.
Thanks and regards,
Manjunath N. Jogin

I do not think this can be done dynamically, You could build several sections, each with it's own graph,
set the scales in each graph, in its section, and then supress sections based on parameter.
So, you could have one section that is 5,10,15,20 etc.
and another that is 8, 12, 16, 20
depending on what they want.

LV7: how to catch 'Value change' event for cursor position in XY graph?

I try to catch an event when the cursor position of a graph's cursor
changes. I created a reference for the cursor array and registered a dynamic
event 'Value change' for it. The event does not fire when the cursor changes
(either by dragging it with the mouse or by direct entry of a new value in
the cursor's X or Y fields. In contrast, when I register e.g. the 'Mouse Up'
event for the cursor array, the event IS detected.
-Franz

So this is the same behaviour as that of a regular control which also does
not fire a 'Value changed' event when it gets updated by e.g. writing to a
local.
At least the cursor's behavior is consistent then...
But unfortunately also the direct user interaction with the cursor's numeric
field does not fire the event, which is NOT consistent.
I was trying to catch cursor changes in my event loop and had used a 'Mouse
Up' event of the graph indicator to look for cursor changes (whose last
position I had kept in a local or shift reg). In order not to miss a direct
user interaction in the numeric field I added the dynamic event 'Value
change' to the same event case, but with no success, it missed the direct
entry ...
according to what you say this seems to b
e a bug then...

How can I add custom captions to a waveform graph scale?

I have an application that displays one or more signals in a WvfmGraph. The X Axis is set by a hardware encoder giving signals vs. distance (measured length). I would like to change the caption of the XScale according to the values of one of the signals. Its similar to an XY graph, but differs in that I want to see the data unrolled.
The problem is that the X Axis scale markers are fixed. I would like to ask the graph what is range property of the X Axis scale. Then use that information and a derived position signal to replace the marker values with values from a derived signal that includes relative motion.
For example, measuring a unit 100 feet long results in measurements of 200 feet worth of data (out and back). The customer would like to see this data unwrapped 0, 50, 100, 50, 0.
One alternative is to use an XY Graph, but the data on top of itself. Not necessarily a bad thing, but not the same as what they have always had.
I found a similar post to display the scale at a rotation (CW or CCW) and was able to get it to work for my specific case. The problem is that my picture marker values are not aligning nicely with the corresponding gridlines.

Stephen,
Thanks for replying to my post. XScale.Range does not handle this situation. In "rigorous" terms, LV does the right thing with X axis scale markers and put them where you want. I tried to set custom Marker values as: {0, 50, 100, 50, 0} and only saw the first three values. My guess is that under the hood, the spacing is set to 'Arbitrary' and my custom values are overwritten. Not what I intended, but I admit my task is not the normal use case.
Today I am prototyping the entire application with each WvfmGraph replaced with XYGraph's. Good thing I used a modular design and passed Refnums around to all my subVI's. Depending on a review of this prototype, I might skip this graph scale formatting.
FYI, the original graph issue wanted to rotate the marker labels CCW. They hid the graphs XScale and used a custom picture to display the new scale. There is a VI that formats an axis with custom labels, where the font, text, etc. can be customized. I have a working example of that custom scale on a Wvfm graph. I stopped refinement when I tried to consider use cases for how the user would zoom on the data, how the graph's label's would appear if the DAQ signal indicated that the part reversed on itself. All the data is better visualized on an XY Graph.
p.s. are you one of the Waterloo Labs engineers? Great stuff!

How do you define graph scales live?

Hello,
I am having an issue with a simple VI I am trying to create that displays test data.
A little background on the setup:
I have an Agilent 34970A data logger recording thermocouple data every 30 seconds which gets appended to a .csv file. My VI opens the data log; reads the contents; manipulates the data; and displays the data on a mixed signal graph. I have one main loop that reads in the data every 30 seconds and another loop inside the main loop that completes approximatly every second to allow changes made to scale controls to take effect so the user doesn't have to wait too long. Because the data logs are allowed to become very long (logs are stopped and re-started daily) it is necessary to allow the user to define, at minimum, the X scale as it is usually the case that the user only cares about what is happening in the last hour or so. The snippet below shows the portion of my block diagram for displaying the data and the user control of the scales.
The problem occurs when the user defines custom scales using the controls shown below. The graph updates as desired however every time the inner loop completes the graph gets refreshed with the default auto scale values before getting set again to the custom scale values causing the graph to "Blip" once a second which is distracting and silly.
Does anyone have any suggestions for me?
Thank You,
Ken

Are the axes set to autoscale? In this case they will autoscale whenever data is written to the terminal.

Graph scale updates on tabs

We have a program with several tabs, each of which has different graphs and displays. On one of the tabs is a histogram style bar graph. We've added annotations to each bar to label each bar with a particular identifier. The graphs are set to autoscaling, so first we write the data to the graph with a "Value" property node, then read back the graph's YMax value and use that to help calculate where to put each annotation. (We typically put the annotation above the bar, but have to limit it to less than the YMax value so it stays on the graph.) Works fine, as long as the graph's tab is displayed.
   So now you're displaying a different tab and put new data into the system. Then click to the aforementioned tab. The new data is displayed, and the graph is properly auto-scaled, but the annotations are out of place. The YMax that was used to calculate their maximum y position was the graph's YMax from the last time it was displayed.
   What appears to be going on is that the graph's display isn't completely updated when LabVIEW knows that the graph isn't visible. When you later make the graph visible, LabVIEW appears to have instantly autoscaled it correctly, but the YMax value that was available when the annotations were being created isn't the YMax that would be expected from the new data.
   Our work-around is to use the maximum Y value of the data. For autoscaled graphs, this is usually pretty similar to the YMax of the axis, but not exactly the same.
   Does anyone have any insights or other ideas? (Synchronous display didn't seem to help. And we couldn't find any other property nodes that might be relevant.)

DaveT,
This may be a complete hack/abomination, but if you are prevented from manipulating your graph if the tab is not visible, you could use an Event Structure and handle the tab's Value Change event. Update your graph within that event.

Reciprocal Graph Scales

I'm trying to plot an XY Graph with one of the scales (x-axis) set to the reciprocal of a variable. I can plot this by calculating the values within an array, however the scales (as would be expected) now show the reciprocated value (ie. 1/value). I would like to plot the reciprocal values whilst still displaying the actual values, similarly to how mapping in log mode would show the value before taking it's logarithm. Essentially I'm wondering if a reciprocal mapping mode can be generated, since the scale varies non-linearly. I'm using LAbview V8.0. Thanks.

Wiebe@CARYA wrote:
Create a property node of the graph, select the Y Scale, and select the property Marker Values[]. With this property, you can set the markers any way you like it (the values are sorted automatically). Use the Flipped property to reverse the scale.
I am pretty sure if this will not work because "stel" wants labels that don't correspond to the underlying plotted data. For example, he wants to show a 10 where the value is actually 0.1, etc.
The proper solution would be to make your own graph in a picture indicator. Have a look at the example "XY Multi Plot.vi" as a starting point.
Unlike the scales of sliders, graph scales unfortunately don't support text labels (Now here's something that could be useful! ). Of course you could cheat, hide the graph axis and substitute a slider with only the axis shown. Now assign label/value pairs of e.g. "10"/0.1, "2"/0.5, etc.. as desired.
Align everything perfectly and make sure to disable "autoadjust scales" on the graph so things don't move around. See how far you get.

Set scale values when zoom out

Hi!
I have a XY Graph and I want it to have three different scale ranges depending on a case structure. So, for example, if it's case 1, I have the xy graph X.minimum = 1,234 and xy graph X.maximum = 10,789 and so on.
I want to be able to zoom the graph but then when I zoom out to see all the points, I want it to have the same range I defined. I have the autoscale turned off and when I do the zoom out, it shows me different minumum and maximum values....
Any help?

Hello Zephirus,
When you ask a zoom out, write the scale value that you define, using a property node. To get it, right click on the XY graphe terminal, in the diagram, then select Create >> Property node >> X (or Y) Scale >> Range then All elements, or just the elements you need to coerce.
Let me know you progression,

Line Item Value change in MIRO Transaction

I have one requirement i.e as follows.
<b>Line Item Value change in MIRO Transaction</b>
After getting the items in table control of the miro screen of a particular order.
I have to clicked on edit own condition of selected item.
then it will show another screen ( create invoice document item - conditions)which have the all condtions details like
Fra1 , frb1 , sd% , Penalty % , gross price , frieght charges etc.
In this screen first time it is showing line item as
in the miro intial screen i.e. if u click po item
10 it will show 10 only.
after updating fra1 value , i came back to the main screen at that time it is asking that select the any one of three.
after selecting manual selection its fra1 was changed.
once again if i go to the same line item by clicking
the edit own condition(13 column if u select all information in textbox whixh is above tablecontrol right corner) it is showing line item as 1 in screen ( create invoice document item - conditions) which should be line item as 10. ( here i took line item as 10)
Please clarify this, why it is showing
first time as a original line item and
after updating it is showing like
for line item 10 -
1
               20 -
2
              100 -
10
              110 -
11.

"...it does not work..." is probably the worst description of a problem you can imagine. As an application developer you should know that. Do you use firebug to see what happens once it "does not work"? Any better hints?

I want the g_item_no (repeating group) to have a page break each time LOCATION changes.

You can declare two variables, to hold the previous and current LOCATION values and break the page when it differs.
Or just before your end-for-each, have this code.
<?if:position()!=1 and position()!=last() and LOCATION!=following::LOCATION[1]?><xsl:attribute name="break-before">page</xsl:attribute><?end if?>
Ensure that its placed in a form field.
This will have a page break when LOCATION changes.

Multicolumn listbox value change and mouse up event in one case of event structure

Hello All,
Am facing two problems:
1. I have two multicolumn events, one is value change for deleting the rows of Multicolumn listbox and another one is mouse up for sorting the columns. But I can't combine both the events in one case. And if I create two separate cases then each time the event of mouse up executes and sorting takes place irrespective of selection of delete event.
2. I have a selection VI in which user selects which parameter he wants to show it in a multicolumn listbox. I want this parameters to be retain or stored when next time I run the VI after closing it.
Am using LabVIEW 11. Pls reply soon.
Thanks & Regards,
Manisha

Double value change event if cursor is set busy (LV2009)

Hello everybody,
I just migrated from LV 8.0 to LV 2009 (on linux) and now got problems with a value change event. I want to send a command if a button is pressed and send another one if the button is released. After sending the command I need to wait for an acknowledge from the receiver and to avoid user interaction in between I lock the cursor with "set busy" VI until the acknowledge is received. To see, when the button is pressed or released, I use a value change event. Inside the event structure the cursor is set busy.
This worked reliable in LV 8.0 but not any more in LV 2009. The button's mechanical action is set to "switch until released" and if I press the button and keep it pressed it is reset to false automatically. The value change event is fired twice instead of only once (see attached vi) and "new value" is one time true and one time false. This doesn't happen if the mechanical action is set to "switch when pressed".
Does anybody have an explanation or a workaround for this behaviour? Am I doing something wrong or is this a bug in LV? For now I'll just keep the cursor unlocked.
Thanks for your help.

It should work if your code was executing correctly. The image you posted...
may be the reason.
If you watch the code in execution highlighting it may help you figure what is happening.
1) There is no guarentee that "initialize" will be written to the local "State" before the loop starts running. Use a shift register to track your state from iteration to iteration.
Do you get any errors?
