Limit on how fine graph with autoscale

Hello all,
I am working
on a temperature controller, and I currently have a graph set up to show the
temperature over time. The autoscale feature works great, however, if I let the
temperature sit for too long, the y-axis autoscale becomes so fine that it
appears that the temperature is fluctuating massively and looks pretty ugly. It gets
in a range of +/- 0.2°C.
Is
there some way that I can limit how fine the autoscale can go? For example, create
the following restriction on the y-axis scale:
Ymax –
Ymin >= 2°C
Thanks
for any help!

Just turn off autoscaling and set the scale min and max using property nodes at appropriate times.
Now you have full programmatic control of the scaling.

Is it possible to add some offset on the Y-Scale of a graph when autoscale mode is enabled.

Hi All,
I am plotting on a waveform graph with autoscale mode enabled. I want to have some offset on the upper and lower side of the Y-Scale. Is there any way of implementing this.
Thanks in advance,
Cooldude

The only way that came to my mind is to do the autoscale by your own:
-Find the min and max (ready vi for that)
-Add a percentage of the range to min and max
-Optional coerce the new min,max accordingly to a round number (depending on log(range) )
-Set Scale with properties
Another way:
Add a plot with same data (or only the min and max point) with tranparent colour and multiply that data with 1.xx (xx percentage additional range)

Thanks for your post in our Discussion Forum,
is it necessary to export the picture in the .emf Format?
Otherwise I can provide two possibilities:
The easiest way to make a screenshot of a certain area of the frontpanel is to
create a SubVI with all the elements you want to take a screenshot from and
then take a screenshot from the whole frontpanel of the SubVI.
This works fine although the frontpanel is not visible while the picture is taken.
The screenshot can be taken with a method-node as seen in the example attached to this post.
Another possibility is to crop a screenshot of a whole frontpanel to the region which you are interested in.
How this works is described here: http://forums.ni.com/t5/LabVIEW/take-screenshot-of-part-of-front-panel/td-p/1613750
The downside is that you have to manually set the region which might change due to scrolling or changes on the panel.
Best regards,
Peter

How to get graphs with steps greater than 10

is this the limit in numbers for graphing y vs x axis data?
I finally figured out how to make 2d line graphs for basic analysis and graphing, (such as temperature vs volume). when I go to edit my data in the chart editor, i can only make steps as much as 10. so if i have 400 degrees, that means my graph will be every 40 on one of the axis... is there a way to increase the steps so that I can have smaller intervals than 1/10th?

I just wanted to check because the workaround for Y axis requires a bit of work and patience.
I built four charts from
column A + column B ( of course you may also select the values to chart)
column A + column C (no X-axis, no labels on X-axis, lines = none, points = none )
column A + column D (no X-axis, no labels on X-axis, lines = none, points = none )
column A + column E (no X-axis, no labels on X-axis, lines = none, points = none )
Define the min and max values to get ten equal intervals in the four charts.
Define the background to none
Superpose the charts with the one built from column A & B at top.
Insert a white rectangle between the upper chart (here Graphique 1) and the three others to hide the extraneous horizontal lines (-30, -20, -10).
This way we have more steps.

How to create ONE graph with a growth trend ($ and %)?

I would like to create a graph with a growth trend.
The graph should have figures on one side reflecting $ values and on the other % growth.
I cannot make a trend on the same graph and usually spend ages adding another graph to show the trend. I end up making 2 graphs instead of one.
Please refer to the following really basic graph that will give you an idea.
ex : http://www.tellurideareahomes.com/images/graph1.jpg
Can anyone show how to do that?

What you want requires a bit of trickery.
Chart the bar graph
Chart the trend
then move the trend one above the bar one after setting its background to none.
If this workaround is not OK for you,
_Go to "Provide Numbers Feedback" in the "Numbers" menu_, describe what you wish.
Then, cross your fingers, and wait _at least_ for iWork'09 (possibly for iWork '99)

Here's a quick example I threw together that generates a sort-of-bell-curve shaped data distribution, then performs the binning and plotting.

How do I create a graph with two different y-axis variables with the same x-axis (therefor having two curves)?, How do I create a graph with two different y-axis variables with the same x-axis (therefor having two curves)?

Hi Libby,
Select all three columns of data. All three must be 'regular' columns, not Header columns, and the X values must be in the leftmost column.
Click the Charts button and choose the Scatter chart.
The resulting chart will initially show only the first and second columns of data, and the selection will have been reduced to show this.
Click the gear icon at the top left of the selection and choose Share X Values.
You should see a result similar to this:
Notes:
The values on my sample table contain a random element, so they have changed from thhe first image to the second.
The chart is as created by Numbers, with two edits:
Data points have been connected with curves, using the Chart nspector.
The curves were selected and their stroke increased to 2pts, using the stroke formating button in the format bar.

How can i control graph with two inputs?

Hi,
i would like to ask you about the graph with two inputs
Normally, if i just give one input, they generate the graph with this input(y) vs time(x).
But now i would like to get the graph with my two inputs in x axis and y axis .
i want to control both of two axis. How could i do for it ?
i attached the file that i try to use "Build XY graph" to control both x and y axis with random number .
It can run but i don't know how come the graph show nothing. .
Actually , it have to show something like wavefrom continuously. am i right?
Could you tell me a way to solve it ?
>>>
what i want to get is ..
in Graph,
for x axis , ditance (always increases)
for y axis , vibration (vary)
>>>
Thank you so much for your time . I am looking forward your kindly reply.
With Respect,
Su

Autoscale XY Graph with 2 plots

I have a graph with 2 different plots on the same Y axis. If I turn off the "visible" property on one of these plots (so I have only one plot visible), the autoscale Y continue to take both plots into account, thus creating a very too large scale for the visible plot. Is there a way to autoscale only one plot while another is hidden but associated with the same scale?

You have several possibilities, for example:
* instead of setting the property to invisible, temporarily replace one graph with empty data. (see attached sample code).
* Don't use autoscale, but use ArrayMinMax on the visible y values, the set the yrange.minimum and yrange.maximum accordingly.
*switch the second plot to a second y scale while invisible and back to scale 1 when visible again.
* any other variation of the above.

How do I make a continuous X-Y graph with an array as input?

I want to create an X-Y graph with a reference time (double) as one variable and the other is a double data type. How can I create a continuous graph on an X-Y graph with these variables? I have only been using Labview for 2 months so if you have any suggestions please go easy on the technical terms.
TIA,
Kevin

LabVIEW what several options for displaying data. A waveform chart is great if you receive one point at a time and want to plot the data in series. A waveform graph is good for plotting arrays in a time series fashion. An xy plot is good for connecting points that do not occur in a series. This plot offers the most flexibility in graphing points with different x values.
It is often hard to keep what structure goes two what display option. As a cheat, I right click on the chart in the block diagram and slide the mouse to create >> (either a constant or control). This way you can get a model for the data you want to input.
You may also want to look at the shipping examples that come with LabVIEW. In LabVIEW 6.1, goto help >> find examples >> fundamen

I have a lion server set up to host storage for time machine backups. Is there a limit to how many different computers can back up to the single server to back up. I am only backing up the users folders . The backup drive is an external Drobo with 6 TB.

I have a lion server set up to host storage for time machine backups. Is there a limit to how many different computers can back up to the single server to back up. I am only backing up the users folders . The backup drive is an external Drobo with 6 TB. Right now it seems to back up my users all day long. I set their time machine interval to every 5 hours but it still runs all day long and is very slow. Server is on a new Mac Server mini.

AFAIK, there is no user limit.. it is simply a question of the network load. AFP is a fairly clean protocol.. but TM is not.. it does a lot of testing of the backup.. infact your setting of 5hour gap could well make it worse.
I would sort out the clients that are doing 100GB backups to a different backup location.. no matter how fast your network.. 100GB takes time to backup.. and over wireless forever.. it will never end.
I guess some of these clients are on wireless?? I would separate the TM of wireless to those that are wired. No more than 4 or 5 wireless clients to a target device. Otherwise you are saturating your network with backup data. And use 5ghz.. so close by.. it is much faster than 2.4ghz and you will get much better transfer rates.

How to evolve a graph with only one loop

1. how to continue to add new nodes to a graph with only one loop
would like to use graph traversal like my previous post to traversal a binary tree, but this time, it can
loop forever, i mean it traverse all nodes in whole graph in the meanwhile it add new nodes too
assume maximum number of joint is 2 or 3
computing nightmare

I just realised that you weren't talking about cyclic graphs (in the case of 1 cycle) here, but meant a single pass traverse and mutate.
What you don't specify is how the new nodes are being supplied. If they are supplied up front, then the loop will of course terminate once all the inputs are addressed, rather than going on forever. If they are being supplied from time-to-time,
then you need to have some sort of event-wait on input. The traversal could have a move-next something like this
If at end of tree with no new nodes, wait for input
If at end of tree, with input, reset to start
If at insertion point for new node at top of input queue, insert that
Move to next node in tree
This seems the sort of thing that would naturally be coded in a functional language as a tail recursion rather than an iteration.

How to make a compass graph with Numbers?

Hi, I did a search for compass graphs and there are a few excel examples, do you know if there are any Numbers, versions, and user friendly ones at that. As I am not a mathematician. Basically I am plotting the frequency of doorway directions to compass points, e.g. N, NNW,NW,W, on a bar chart, but the paper I am comparing it to, has used a compass graph, with the freqency as longer lines eminating from the compass point depending on the number of doorways.
The directions could be input as degrees if required. Any help appreciated

Hi Nanouk,
A compass graph would certainly be appropriate for this data, but that chart type is not available in Numbers.
You can fake it with a little work, though.
Arrange the data in pairs as shown. Note that the values in column C are expressed as negatives.
Create four Stacked Bar charts, one from each data pair. You will need to click the three bar icon that appears at the upper left of the selection to change it from horizontal to vertical. That makes Numbers consider the pair as parts of the same series, and stack the two bars.
Open the Chart Inspector and for each chart, remove everything except the actual bar, and for now, the Label on the X axis (if this helps identify which graph shows each pair). Set the Y Max to the maximum expected value, Steps to 1 and Y Min to the negative of the Max value. Use the Pen and Fill controls in the Toolbar to set the Fill colour to None and the Line to None.
Switch to the Metrics Inspector (ruler icon) and set the size of each chart to the same values (I used 0.5 wide and 4.88 high (with Max Y set to 10).
Drag (or use the arrow keys, with or without the shift key) the four charts into place.
Add as many circles (from the Shape button—be sure to set Fill to None) as you want and drage them into position.
I left the bars in the default colours to assist in lining them up correctly. Those colours can be changed by clicking on the individual bar, then using the Fill well.
Too fiddley? You could just dump the data into NeoOffice and use that to create a Compass chart.
Here's one produced from the same data set.
Graph from NeoOffice (same data, in single column, all positive values).

Barry
