Do you mean the **description** which is in the bottom right corner (default) of the `Chart`?

If so, simply call:

`chart.getDescription().setEnabled(false);`

Or did you mean the **textual description** inside the pie-slices?

`pieChart.setDrawSliceText(false);`

Or did you mean the actual **slice values** inside the pie-slices?

`pieData.setDrawValues(false);`

Or are you talking about the [Legend](https://weeklycoding.com/mpandroidchart-documentation/legend/) (shows all `DataSet` labels and colors outside of the chart)?

`chart.getLegend().setEnabled(false);`

This answer is based on [release v3.0.0+](https://github.com/PhilJay/MPAndroidChart/releases), for more information check out the [**documentation**](https://weeklycoding.com/mpandroidchart-documentation).


In the new version you can do it like this:

    Description des = Chart.getDescription();
    des.setEnabled(false);

If you want to remove the legend:

    Legend leg = Chart.getLegend();
    leg.setEnabled(false);



# you can remove it by simply passing null into it. 

pieChart.setDescription(null);

in kotlin use 

```
chart.description.isEnabled = false
```

Let&#39;s say I have 3 inputs: rate, sendAmount, and receiveAmount. I put that 3 inputs on useEffect diffing params. The rules are:

 - If sendAmount changed, I calculate `receiveAmount = sendAmount * rate`
 - If receiveAmount changed, I calculate `sendAmount = receiveAmount / rate`
 - If rate changed, I calculate `receiveAmount = sendAmount * rate` when `sendAmount &gt; 0` or I calculate `sendAmount = receiveAmount / rate` when `receiveAmount &gt; 0`

Here is the codesandbox https://codesandbox.io/s/pkl6vn7x6j to demonstrate the problem.

Is there a way to compare the `oldValues` and `newValues` like on `componentDidUpdate` instead of making 3 handlers for this case?

Thanks

Here is my final solution with `usePrevious`
https://codesandbox.io/s/30n01w2r06

In this case, I cannot use multiple `useEffect` because each change is leading to the same network call. That&#39;s why I also use `changeCount` to track the change too. This `changeCount` also helpful to track changes from local only, so I can prevent unnecessary network call because of changes from the server.

I have an app where I capture a video using the camera. I can get the video&#39;s file path, but I need it as a Uri.

The file path I&#39;m getting:

    /storage/emulated/0/DCIM/Camera/20141219_133139.mp4

What I need is like this:

    content//media/external/video/media/18576.

This is my code.


    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	        // if the result is capturing Image
	       
	         if (requestCode == CAMERA_CAPTURE_VIDEO_REQUEST_CODE) {
	            if (resultCode == RESULT_OK) {
	                // video successfully recorded
	                // preview the recorded video
	            	// selectedImageUri = data.getData();
	            	// Uri selectedImage = data.getData();
	                previewVideo();
	              
	                tv1.setText(String.valueOf((fileUri.getPath())));
	                String bedroom=String.valueOf((fileUri.getPath()));
	                Intent i = new Intent();
	                i.putExtra(bhk1.BEDROOM2, bedroom);
	                setResult(RESULT_OK,i); 
	                btnRecordVideo.setText(&quot;ReTake Video&quot;);
	              
	            } else if (resultCode == RESULT_CANCELED) {
	                // user cancelled recording
	                Toast.makeText(getApplicationContext(),
	                        &quot;User cancelled video recording&quot;, Toast.LENGTH_SHORT)
	                        .show();
	            } else {
	                // failed to record video
	                Toast.makeText(getApplicationContext(),
	                        &quot;Sorry! Failed to record video&quot;, Toast.LENGTH_SHORT)
