swift3 - iOS Charts, wavy lines -

-



let's straight point: started use ios charts daniel gindi, can't reproduce wavy lines in line chart enter image description here

(and please notice image picked form repository of ios charts!)

all this, simple straight lines no curves enter image description here

and code in viewdidload used showing that:

    let ys1 = array(1..<10).map { x in return sin(double(x) / 2.0 / 3.141 * 1.5) }     let ys2 = array(1..<10).map { x in return cos(double(x) / 2.0 / 3.141) }      let yse1 = ys1.enumerated().map { x, y in return chartdataentry(x: double(x), y: y) }     let yse2 = ys2.enumerated().map { x, y in return chartdataentry(x: double(x), y: y) }      let data = linechartdata()     let ds1 = linechartdataset(values: yse1, label: "hello")     ds1.colors = [nsuicolor.red]     ds1.drawcirclesenabled = false     ds1.drawvaluesenabled = false     data.adddataset(ds1)      let ds2 = linechartdataset(values: yse2, label: "world")     ds2.colors = [nsuicolor.blue]     ds2.drawcirclesenabled = false     ds2.drawvaluesenabled = false     data.adddataset(ds2)     self.viewchart.data = data      self.viewchart.gridbackgroundcolor = nsuicolor.white      self.viewchart.chartdescription?.text = "linechart demo"

can me? thank you!

please check :

let ds1 = linechartdataset(values: yse1, label: "hello") ds1.colors = [nsuicolor.red] ds1.drawcirclesenabled = false ds1.drawvaluesenabled = false ds1.mode = .cubicbezier // add line data.adddataset(ds1)  let ds2 = linechartdataset(values: yse2, label: "world") ds2.colors = [nsuicolor.blue] ds2.drawcirclesenabled = false ds2.drawvaluesenabled = false ds2.mode = .cubicbezier // add line data.adddataset(ds2)

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
