## What is LDViewer?
LDViewer is a Google Web Toolkit (GWT) widget containing a [processingjs][0] sketch for visualizing [LD triangle plots][1].
## How do I use it?
Following steps are required:
```JAVA
LDViewer ldviewer = new LDViewer();
ldviewer.load(new Runnable() {
@Override
public void run() {
GWT.log("LDViewer loaded");
// Interact with sketch
ldviewer.showLDValues();
}
});
```
To display data users have to call the `showLDValues(int[] positions,float[][] r2Values, int start, int end)` function with following parameters:
- `positions`: Array of integer
- `r2Values`: multi-dimensional array of floats in a [triangular matrix][2] form.
- `start`: start position (should be the first position of the position array)
- `end`: end position (should be the last position of the position array)
An [example of this data][3] can be found in the sample application and one could load it this way:
```JAVA
final String jsonData = GET_FROM_CLIENTBUNDLE OR AJAX CALL
LDData data = JsonUtils.safeEval(jsonData);
```
## How do I install it?
If you're using Maven, you can add the following to your ``
section:
```xml
com.github.timeu.gwtlibs.ldviewer
ldviewer
1.0.0
```
LDViewer uses [GWT 2.8's][4] new [JSInterop feature][5] and thus it has to be enabled in the GWT compiler args.
For maven:
```xml
-generateJsInteropExports
```
or passing it to the compiler via `-generateJsInteropExports`
You can also download the [jar][1] directly or check out the source using git
from and build it yourself. Once
you've installed LDViewer, be sure to inherit the module in your .gwt.xml
file like this:
```xml
```
## Where can I learn more?
* Check out the [sample app][6] ([Source Code][7]) for a full example of using LDViewer.
