White, red, and green lines are some levels, according to a criterion, and blue line is measured spectrum, in upper picture.
Now, I want to attach the names of the lines, corresponding to levels, on the right end of lines.
The below picture is what I expect.
I couldn't find any plot property for these work.
Could anyone help me?
Thanks in advance.
You can use the Annotation List property to set annotations at specific points in the graph and I believe also link them to plots.
I have no practical experience with it, so I'm not familiar with all it can do. It might also give you the ability to manipulate specific annotations, etc. Play with it and see.
Here is the solution for the problem: https://lavag.org/topic/17756-xy-graph-programmatically-add-point-labels/
It uses Annotation List property as Yair told already.

I am trying to match the "teletext holidays" in the image below (with the white bits connecting all the letters:
I have achieved the following by going to the layers section, right-clicking the text layer, and select “Blending Options.” Then marking the checkbox next to “Stroke.”
Any hints or tips to point me in the correct direction would be appreciated. I appreciate moving the letters within the font closer together will help so will work on that now.
Any help appreciated.
Update:
Made the letters appear closer together. However, using stroke is making the black letters "shrink" in size so think a different solution is required. Thoughts?
With regard to that final image and the black letters appearing smaller. When applying the stroke, tick to indicate that it should be outside and not center or inside
And with helping to ensure that the white parts do meet.... Hmm... Well. Difficult to do the horiztonal stroke without it also applying vertically.
I would agree with others that Illustrator would be better but in Photoshop I might try to duplicate the text, make it all white, put it on the layer behind your main text and manually create a horizontal white pattern.
^ I really hope somebody has a better idea for that last bit though.
Alan,
I would like to help you with this issue. First of all your reference design is designed in adobe illustrator not in photoshop because there is some limitation in photoshop for the stroke feature.
So I would like to suggest you design it in adobe illustrator and not waste your valuable time in photoshop for your desired output.
If you need more help regarding it feel free to contact me at niravmistrydata#gmail.com.
Thank you,

Im not sure how else I should approach it, but if I was to (in my mac application) have a grid of NSViews, which the user can change the colour of each, is it possible to then translate this, so now I have been given a colour for each pixel by the user, make this into an exportable image?
I honestly can't think of how else to do this. I don't want to go ahead an realise I have taken a rather foolish path.
The idea is I will have a grid of squares which the user can paint, a colour in each square, a square representing a pixel in the final image. So they paint with like a paint bucket filling each one, then export it into an actual image file.
Any help much appreciated, thanks.
A grid of NSViews sounds really heavy for what you're doing. Why not write one single custom view that checks the mouse position and modifies the data appropriately? Then you'd write a custom drawing method to fill the custom view, and you could use the same exact draw method to write to an NSImage which you could export.
You'll need to do a bit o' math. For each "pixel", call -set on the appropriate NSColor, then use NSBezierPath's -fillRect method. It may help you to get out a pencil & paper to figure out the math for the rect origins & sizes.
Check http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CocoaDrawingGuide/Introduction/Introduction.html for help if you've never done custom drawing before. It's really not that bad, just takes a little reading. :)
I need to paint the line which links two points.
I am doing it, in Java. I receive two points as parameters and I have to calculate if the straight line between them, is inside the black figure.
I developed my own solution using the straight line equation, but my results are different than using the "professional" programs (such as GIMP or even MS Paint).
Here is a example of what I want:

But my algorithm does this:

*The green point is out of the figure and this is not possible.
Any ideas? Anyone know which code is been using for this, in "professional" apps?
Thanks!
Daniel.
EDIT: Images
It looks like you are truncating instead of rounding to the nearest pixel. Difficult to see on those small black ink splotches. Could you post the code?
"Professional" programs most likely use Bresenham's line algorithm.
Look at Bresenham's line drawing algorithm
Straignt lines are drawn using Bresenham's algorithm usually. I didn't get your point about green point being out of the figure - there's clipping to not waste time drawing outside the visible area.
I'm completely new to ArcGIS and ArcMap, but someone suggested this program to me for a project I'm working on.
I would like to animate individual entities on a map, and was wondering if it is possible to do so in ArcMap. I asked this earlier here and a member directed me to a tutorial on animating in ArcGIS. The animation in the guide was over a map spread (ie. each pixel on the map displays, say, a different color to indicate population data in the area). However I realized that if I zoom in a lot, eventually the image will degenerate into pixels, which is why I need an actual object to mark a certain point. I checked some online tutorials and it seems like we can place markers on the map. Can someone tell me if it is possible to animate these markers (for example via a for-loop)? And if so, could you point me in a direction where to start?
Thanks in advance!
You can animate layers in ArcMap is the short answer. Its not as simple as using the timeline feature in Google Earth for example though. But then ArcMap is much more than just a visualization tool.
This help page on the ESRI web help looks like a good place to start.
I'm not 100% sure what you mean by the image degenerates into pixels. Are you saying that the markers were single points in the layer. Unlike Google Earth you are not confined to simply plotting points on the map. You can draw completely arbitrary shapes in ArcMap, which can be defined to cover actual areas of the map, so when you zoom-in the shape gets larger.
The way you need to load data into ArcMap to produce an animation isn't too simple. There might be other ways to do this, but the way I know of is to generate a NetCDF file. This file contains a 3D matrix of layer data, where each layer is separated through time. Because you generate a matrix, you are effectively placing a raster image over the map. Thus if you want to cover a large area, each matrix becomes large, and you multiply that by the number of time slices you wish to animate over.
Once you have a NetCDF file with your data in however, getting ArcMap to animate it and produce say a .avi file is pretty simple.
You could try just loading some of the example NetCDF datasets into ArcMap to see how/if they will work to get you started.
Hope that helps.
The upcoming v10 will have better time-aware capabilities, which will allow for animation.
I'm playing around and try to make a Coloring book for my children and I have a lots of black and white line drawings that I use as backgrounds so they they can paint on them.
Now, I want to add a FILL-function so they can point and click somewhere where its white in the drawing and then let the function fill the whole region within its bounds with a color.
It would be nice to have a function that by sending in X, Y and a color defined for the boundary and get a region out of it. Then its just about to do e.Graphics.FillRegion (brush,region) to fill it with the color.
But I can't find any function that allowes me doing that, and I think its too much job to trace the boundarys myself.
Have I missed some function in the system.drawing class that does this or do you have any other ideas?
Any other ideas for the coloring book-program are also interesting. (Im making the program safe so you can leave the kid in front of the computer without being afraid of the kid accessing any other things on the computer and have different funny sounds when selecting colors and so on)
If the "boundary" is defined by differently-colored pixels and not a mathematical formula or a Path data structure, you will have to test and fill individual pixels. There is an article on how to flood fill in .Net at Code Project.
Look into flood fill methods. Wikipedia has plenty of information on the subject here.
