google app engine - Upload binary file to GAE Python Blobstore -


i can upload text files (.csv, .json) code, can't upload excel file (.xls or .xlsx).

class createteam(blobstore_handlers.blobstoreuploadhandler, basehandler):     def get(self):         upload_url = blobstore.create_upload_url('/create_team')         context = {'upload_url': upload_url}         self.render('create_team.html', **context)      def post(self):         blob_info = self.get_uploads('file')[0]         blob_key = blob_info.key()         blob_reader = blobstore.blobreader(blob_key)         file_data = blob_reader.read()  # line stalls out         blobstore.delete(blob_key())         self.redirect('/')

when try one-line .xls file, blob_reader.read() line locks on mac. in browser (chrome), tab icon seems spin forever , gae launcher freezes up. have quit , start over.

my html looks this:

<form method="post" action={{ upload_url }} enctype="multipart/form-data">     <div>         <p>upload file</p>         <input type="file" name="file">     </div> </form>

do binary files handled differently uploads? form above over-simplified. have other form elements posted @ same time.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
