Increase resolution of graphic displays?

[coolhandLV7]

I am using an intensity chart to plot XYZ data where (Z) is a color ramp, all seems to work fine however the display of each line is really pixelated.  The LabVIEW software is built to control a sensors setup and output but display similarly to the vendor (Keyence LJ-V) interface, the vendor interface is much higher resolution and is able to display the data with higher detail. 

Is there a way to turn up the juice on the LabVIEW displays in terms of resolution so that features are sharp and more visible?

Hi coolhand,

yes.

Search for Christian Altenbachs threads on 2d interpolation. He has posted very nice examples on how to increase "resolution" of (2D data in) intensity graphs.

Charts are a bit different, because data is continuously appended. Is the "pixelation" in the t or y direction or both? Maybe a logarithmic z mapping would work better? Hard to give advice without a picture.

i've attached a sample picture.

I also tried the bilinear and 2D interpolated methods, i cant get either to work for this data set.  Anyway my work around is just to display more data by increasing the window size...really a band-aid though.

Well, the image is just data and if a value is <90, you'll get a black pixel. What does the data represent? What is the size of the data in each dimension? How do you want it to look like instead?

Is this really a chart or is it a graph? (hard to tell from the x axis)

Can you attach a simple example that contains the data currently displayed?

There dozens of ways to make it work and there are billions of ways for it to fail. If you say you "can't get it to work", you are not really narrowing down the problem. What did you try and what happened (error, wrong result, broken wire, computer crash).

Also have a look at the examples listed here.
