javascript - Chartjs, How to make x tick space be different on line chart -

-



i want use line chart , make such each x value maps it's respective y value based upon index. example know can this:

labels: [1,2,10,20]

and have data be:

data: [1,2,3,20]

which produce this: graph

as can see space between 2 , 10 same x axis labels. want insert labels/data using same format (data:[1,2...]) want x axis realize spacing between each value should scaled depending on x value given still mapped y value.

i know can insert data this: 

data: [{          x: -10,          y: 0         }]

but there way without having change format , have index based instead?

python - Read npy file directly from S3 StreamingBody -

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
