Create contour plot

Hi,
I'm trying to create a contour plot from data stored in a measurement file (lvm).
The data file consists of time (x), size (y) and a concentration corresponding to each xy.
I want to show the concentration in colour intensities and not as numbers.
I've started with the "read from measurement file", but I don't know how to convert the data that is read to a x, y and z-vector, to be able to plot it afterwards .
What graph can I use best to plot the x, y, z vector? A 3d surface Active X container?
Thank you in advance!

2d contour plot with variable x,y spacing

Hi
How do I create a 2d contour plot with the the x-y values spaced at irregular intervals? Intensity plots appear to require equally spaced data.
Any ideas
Thanks
Willem

Hi Willem,
You are correct in saying that intensity plots require regularly spaced data.
The easiest way to get round this is by padding out your data so that it is regular.
Does your data have a common multiple, if so you can simpley scale it by that factor to make your data regular.

How can I prevent a memory flow error from occuring when using 3D contour plots?

After displaying a single contour plot a number of times, LabVIEW crashes and reports a memory overflow error. I only load a single 2D array, never storing previouls ones. I always index the data for contour plot 0, and don't explicitly store multiple 2D arrays in any buffer, such as appending data to a shift register. There appears to be some sort of memory leak in LV when using this feature. Is there a programatic way to flush the stored data in a contour plot prior to displaying the next 2D array of data?

Hello MicTomReiSr,
Is this in the LabVIEW development environment? Are you making changes to the code and then running the VI? Does the plot contain default data? Is the indicator cleared when the program stops? The Plot Clean Data method may be what you're looking for.
Remember that the development environment maintains an undo history of the changes you've made, and copies both the block diagram and FP contents each time. If you have a lot of data displayed on the front panel you end up copying it multiple times. This isn't a problem unless you're actively editing the VI in question.
If you do need to edit and run the VI at the same time (perfectly reasonable, although you might want to consider a 64-bit installation or more RAM if you commonly work with resource-intensive data types like 3D plots) try reducing the Undo history length (Tools>>Options), although be aware that you won't be able to back up as many steps.

You draw them manually. There is no built-in functionality. AI simply sucks for any kind of diagrams.

Hello aveo,
how about using the "IMAQ 3D View". Please see the attached code saved for LV2010.
Does this suit your application?

Contour Plotting

Can any one suggest me a good site for contour plotting or any jar file exits which help me in plotting contour plot graphs.

There's a huge, comprehensive and open-source GIS package called "GRASS", admittedly written quite a while back in C. It's very modular, with a class or two for each of dozens of commands, so it's quite a good source of example code for stuff like that.
(Grass is originally a US military project).

How do you create stacked plots?

Okay, I have tried for quite some time today to create a stacked plot, but without any success. I want to be able to put in a max and min range for the x-axis on the front panel. This x-axis will be used for three different y-axis. Each y-axis will have a different scale than the other ones. Also, each y-axis will have up to 6 different plots. I have attached an example of what I hope the final chart/graph/plot will look like. I have tried combining the x-axis values with the different y-axis values in an array (2D) and then plotting them but nothing seems to work right.

Never had much success getting what I consider "publication quality" graphs out of LV, but that is not what it was built for. It has a great looking GUI and the flexibility to get your data into a program to suit your needs. Doesn't mean that there aren't some features we'd like to see added, especially when it comes to axes and labelling. My advice to you is the following:
1. take a deep breath and decide if this is something you really want to do.
2. perhaps try an in-between solution like stripping down the plots and stacking three XY graphs on top of each other. You can programatically control the scales. You won't have overlap of the plots like you show, and all of the labels will be on the left.
3. Try a standard XY graph and fudge the labels using Ben's very elegant trick. Ben is the go-to-guy (IMO) for picture control questions
4. Explore the Picture VIs to generate plots piece-by-piece. You are in for a lot of work, but it is the only LV-only solution I know to get the results you are looking for. (Perhaps there are new and exciting features in LV2009 that someone will enlighten us with).
5. Do what I do. I use a MathLink connection to Mathematica when I need plots that I can't get easily in LV. You can retrieve the graphics object and display it in a container or a picture control. I use a picture control because the container seems to unload the image when I stop the VI. If you don't have Mathematica, or similar program, sorry.

Need to know how to create 'contours' around artwork for printing?

Hello Friends,
First, let it be known that I am new to InDesign.
Actually, this will be the first time I will be using it!
I created a logo in Photoshop, for a friend to take to the printers which would be transferred to a plastic sticker.
The person at the printers told my friend that he would need to have contours in the artwork. When asked how could that be accomplished, the printer guy said that it could be done through InDesign...
I have access to InDesign CS5, but am at a loss as to how to figure out how exactly to accomplish this.
I have searched both Google and here, to no avail.
Any help would be highly appreciated.
Warm Regards,
Isa.

Thank you for your reply. I am creating a new OA Framework form to display Oracle project and tasks under the project. I was able to create a tree for one task and its subtasks, but I want to make the project as the top most node, and have all the top level tasks as the project's children. I created a view to make the project like a parent task for all top level tasks, and created a VO based on this view. But my tree structure messes up. Do you know where I can find sample code or tutorials on OAF tree structure? I greatly appreciate your help.

How to create Forest plots (odds ration plots) in Keynote '09?

Hello,
I am trying to convert to Keynote from PowerPoint and I was wondering how to create odds ratio plots without drawing them out. These are plots of an odds ratio and its 95% confidence interval.
In PowerPoint, one creates a line chart, removes the lines leaving the data points, and then adds high-low bars for each data point. Easy.
How do I do this in iWork/Keynote?
Thanks for any help.
Sunil

A line chart is a "Category" chart.
One axis, usually the 'x' axis, is a Category axis. The category axis does not show numerical values (even if the values are numbers, they are simply text that names each category). Categories are evenly spaced along this axis. Labels for the categories must be placed into a Header Column.
Values shown on the Value axis (usually the 'y' axis) are numerical.
Here are two examples of the same data, presented first as a scatter chart with the data points connected by line segnments, then as a line graph.
Note the differences in organization of the table, and the differences in spacing along the x axis.
Scatter chart:
All data in 'body' cells. Series labels in Header row. Note the shape of the line for Data series B (Green) and C (Yellow).
Line Chart:
Category labels in a Header column (Column A), Data series labels in a Header Row (Row 1). The 'numbers ' in column A are seen as text, and a regularly spaced along the x axis.
Data series in regular cells (B2:D8) Only the data cells are selected when making the chart.
Note the shapes of the lines for data series B (Green) and C (Yellow).
For your setup, you would need to place the 'x' values into a Header column. The Y values in columns Y, Z and AA could stay in those columns.
You would select only columns Y, Z and AA, then make the Line chart, as I've done in the example below after inserting some new columns to the left of that data.

Barry

Creating contour lines within text

I am trying to create artwork for use in a laser machine. I have some directions on how to create it in Corel, but I'm Illustrator based and I can't seem to convert the terminology over to Illustrator. I'm trying to create text that is filled with contour lines so that when it's sent to the laser it will vector engrave the fill instead of doing a solid fill with the raster etching. Attached is a picture that might help explain what I need to accomplish. Thanks in advance for the help.

oldmountaincrafts,
Basically, you can work with Object>Path>Offset Path with a negative value equalling the distance between lines.
There may/will be some adaptations when the shapes switch from following the whole shapes to partial shapes.
You may:
1) Create the live Type;
2) Type>Create Outlines, then switch from fill to a suitable stroke;
3) Object>Path>Offset Path as many times as needed, possibly switching to partial shapes for the last bits, possibly using Object>Compound Path>Release.
Below is the result up to the final adaptation for a 72pt Helvetica with a Stroke weight of 0.5pt and an offset of -1pt. The innermost bits of the B, a, and b, form Compound Paths which must be released so you can work on with each bit individually. You may also delete and replace parts and use simpler paths, such as curved paths in B, curved and curved/straight paths in a, and curved and straight paths in b.

Programmatically Create/Hide Plots

All,
I would like to programmatically set the visibility of plots and tab control pages. The solution I came up with was to place visibility property nodes in a case structure and based on the value of the control, that many plots would be made visible. However, placing all of those property nodes is tedious and I don't think this solution is scalable -- ultimately, I will have many more plots than what I included in the example VI.
What is the most efficient and elegant method for controlling the visibility of a large number of plots?
Regards,
Andrew

Create an array of references for all your graphs. Now you can programmatically feed them into a For Loop with autoindexing into a Visible Property node.
